} ...Lady NicMaoilan writes about eyeglasses in the SCA, and that she has

} never seen an attempt at period eyeglasses. Ah, but I have!

}

} A gentle in our area, Mistress Margaret of Shaftesbury, owns a pair, which

} her dear lord, Master Einar, made for her.... in a period manner. The

} frames are of wood, round in shape and quite thick, and nestled within are

} round lenses. The glasses rest on the bridge of her nose, and are held on

} by two loops of ribbon that hook totally around her ears....

 

Are wooden frames "more period" -- or more common in period -- than

metal ones?

 

(Here's some material I recently found on eyeglasses in Phil Morrison's

*The Ring of Truth* I haven't got the source here, so I'm relying on

memory for the indicated details.)

 

The earliest picture of someone wearing spectacles that I know about is

a painting on the wall of a monastery in Italy (Treviso, I think) --

near Venice, of course, and the legendary Venetian glassworkers.

 

The portrait clearly shows a scholarly-looking fellow (the Abbot?) with

a pair of small round-lensed spectacles, with what certainly appear to

be wire frames.  They are perched on his nose, and hooked round his ears

in the modern way.  The date of the painting is, I believe, c. 1340 (but

I may have that a century too early).

 

(By the way, our earliest evidence for eyeglasses at all is the record

of sermon given in 1305, which says, essentially, "It is not quite 20

years since the invention of those spectacles which enable those elderly

with weakened eyesight to continue reading and writing.")

 

I can dig up more, if anyone wants.  Personally, I'd like to know if

anyone on the Rialto has studied or worked on period lens grinding.

      Eyeglasses are indeed period.  Even I belive pre SCA period in ASIA,

appearing in Europe in the late part of our period.  There is a nice pamplet

of Complete Anachronist that includes How-to for period eyeglasses.

      In an Art History course I took this summer, I saw a painting dated

around 1435 (? I hope I am recalling correctly!) a Maddona and child with an

attendant Cardinal holding a book and some dark rimmed (horn? metal?)

pince-nez type eyeglasses. That would be a primary resource right ???

I've just been reading "The Autobiography of Henry VIII" and the

author has Henry tell us that he's been forced to wear "40-year

spectacles" to read documents and he laments that he'll have to wear

50-yr and 60-yr glasses if he lives so long.

 

Obviously, this is a work of fiction, but the author did a _lot_ of

research; an excellent bibliography is included.  I've got her book on

Mary, Queen of Scots, too and it's also excellent--a pity that Mary

was such a _foolish_ woman.

      I was just reading my assignment for last Monday and came across an

interesting comment that I thought might apply to your conversation.  I haven't

been paying too much attention to this thread, but I think the earliest date I

heard mentioned was early 16th c., so:

 

From Petrarch's "Letter to Posterity" (trans. and ed. by Mark Musa in The_

Italian_Renaissance_Reader),

      "I had ... for many years sharp vision, which, however, unexpectedly

deserted me when I passed my sixtieth birthday, and forced me, reluctantly, to

resort to the use of glasses."

 

      I unfortunately don't know when he wrote the later, but he turned 60 in

1364 and died in 1374.  I don't know Italian so I can't say anything about the

translation (Although it's in the second paragraph if anyone cares to check.),

but if it is right that dates glasses back to the 14th c.

      Just as another thought, he might be referring to a monocule or

lognette (sp?) as well, but at least some kind of corrective lens was available.

 

      In Service,

      Geoffrey Scrymger

About tolerating eyeglasses...

 

'course, eyeglasses are period.  However, IMSC, they were of the type

to correct far-sightedness, what we might call reading glasses.  IME,

SCAdians tend to be nearsighted, rather than farsighted, so from a

strict standpoint, most of our glasses wouldn't even be period, even

if the frames were.

 

(I had a "pseudo-set" of period glasses...one of my earpieces broke.

Remembering an illustration of what Elizabethan glasses looked like, I

tried to follow it with dismal success...fortunately it was only a

month before I could get new glasses)

 

Sunglasses are period.  Sort of.  Anyway, that's what I've read.  What

you do is take regular glasses, paint linseed oil on them, and

bake'em. The linseed oil turns black; if you did everything

correctly, you'll still be able to see through the glasses after

you're done.

 

Unfortunately, Medievaloid is "in" in the fashion-world.  This means

that you can get medieval-looking eyeglass frames, but they're

designer frames and cost accordingly (i.e., between 10 and 100 times

what they're actually worth).  I know; I tried to get a pair but it

would have cost me over $100.

 

If there are opticians in the SCA, I'm sure there would be many people

_very_ interested in getting a medieval set of glasses.

RE>Glasses....

 

   Hi Stefan,

 

   Van Eyks "Annunciation" is a painting that shows a Cardinal I think who

   is holding a pair of glasses. Van Eyk is reknown for his realist details

   (early to mid 1400's) so the inclusion of glasses as well as the absence

   of temples is signifigant. Quite a detailed painting too. I do like the

   northern renn artwork so much more than the Italian as it is *much*

   more secular in nature and hence valuable for my purposes! :-) I think

   the date for the piece is 1430, but could easily be off by a decade or

   so.

Umberto Eco, who I have found reliable in his fiction for

everything but windows and functional herbology, maintains

(in the NOVEL <underlined> Name of the Rose) that pince-nez

metal glasses, (as opposed to the ones on Henry VIII's

grotesque helm and featured in Complete Anachronist I) were

becoming available in the mid 1300s.

 

BUT: a problem - the glasses were reading glasses for the

far-sighted. Several people in society maintain that glasses

for the nearsighted were a later development. Then again, no

one is likely to check whether your lenses are double-convex

or plano- or double-concave. (I don't buy that for one

reason. The general method of grinding a convex lense leaves

you with a concave lense - look at any manual on telescope

making for further details on how to grind your own)

Umberto Eco's Pince-nez ("pinched nose") glasses are quite similar

to Henry VIII's helm (although I haven't seen the spectacles in the

CA I).

 

Essentially, we are talking about a pair of round lenses on a

hinged section.  This hinged bit may be a small arc, or a longish

handle. A 14th C. pair, similar in appearance to those used in the

movie "Name of the Rose", but made from bone were excavated from

the Trig Lane excavations in London.  [there are at least 2

articles on this topic by Michael Rhodes, one in _London

Archaeologist_ 4 (1980), 23-5; and the other in _Antiquaries

Journal_ 62 (1982), 57-73.  Both are discussed in Arthur McGregor's

_Bone, Antler, Ivory and Horn_]

 

In my brand new copy of _Ancient Inventions_ by Peter James and

Nick Thorpe there is a discussion on Spectacles (pp.289-295) [using

as IT's major source, E. Rosen., "Invention of Eyeglasses,"

_Journal of the History of Medicine_ 11 (Jan 1956), pp.13-46;

(April 1956), pp 183-218), which I have not, as yet, seen].

It describes (as well as shows) a fresco by Tommaso di Modena,

painted in 1352 showing a pair of spectacles with the curved

hinge/nose-piece. There is also a mention of a sermon by a

Dominican Friar Giordano da Rivalto deleivered in 1305, reporting

that 20 years before, a man the good friar had actually met, had

invented the spectacles.  Unfortunately, this is an area wherein a

lot of hoaxes have been perpetrated (and to be honest, since this

is, at best, a fourth-hand source, I will take it as merely an

interesting hypothesis until I can backtrack the documentation).

 

However, as the current version of my persona is convinced that

this is 1115, such an invention in 1285 seems a trifle "high tech".

 

>BUT: a problem - the glasses were reading glasses for the

>far-sighted. Several people in society maintain that glasses

OTOH, This same nifty new tome has a section on Magnifying lenses

(pp.157-161), in which it repeats the old from Pliny about Nero's

_smaragdus_, which is reputed to be "Concave in shape, so that it

concentrates the vision".  Ie., a lens for us myopics.

 

>The killer comes for photophobes like me - I've yet to find

I can relate to that.  However, should Nero's smaragdus actually

have been an emerald...

 

Personally, however, I try to stick with a broad brimmed hat

whenever I can, and keeping my eyes closed a lot.

I beg to differ.  Brother William's Spectacles are described as

   "...It was a forked pin, so constructed that it could stay on

a man's nose ... as a rider remains astride his horse or as a bird

clings to its perch.  And, one on either side of the fork, there

were two ovals of metal, which held two almonds of glass, thick as

the bottom of a tumbler. ..." (p.74 of the 1983 Harcourt Brace and

Jovanovich edition)

 

The twin ovals of metal, one on either side of a fork sound to me

to be very like the versions used in the movie, and that I have

heretofore described.

 

>>...concentrates the vision".  Ie., a lens for us myopics.

>Thank You For the Cite!

 

My pleasure.  Please let me know if you find that it is in error.

It just so happens...

 

Actually, not.  The best I can do is suggest a source for false

amber made from *real* amber blended with some sort of plastic.

I've never used it myself, but I'm told that it can be worked as

easily as real amber, and is significantly cheaper.  The company

makes similar faux gemstone plastics from real gems.   If you are

interested, I'll get the address...

It seems that the 1285 date for spectacles is likely to be the earliest date.  

Regulations from the Venetian Glassmakers' Guild which refers to spectacle

lenses dates from about 1300 and would seem to confirm the date.  However, a

number of rock-crytal lenses have been found around the Mediterranean,

including Turkey and Crete, and seem to date from various periods befor the

second century AD.  Although there seems to be no evidence for them having

been fitted into spectacles, there is no evidence that says that they were

not.

 

A reference in a Chinese work, previously thought to date from about 1240 AD,

is now believed to date from sometime after 1410.  It referred to a gift of

spectacles to the Emperor of China from the King of Malacca, on the Malaysian

peninsula, and this is also referred to in some court records which have been

positively dated to 1410.

 

OTOH, Aleksandr, your sunglasses may actually be available earlier, if you can

establish Chinese connection through trade.  There is a refernce to Judges

wearimg dark glasses made of smoky quartz, not as aprotection against the sun

but to disguise their reactions to evidence read out to them in court.

 

As an alternative the Inuit developed carved ivory or wooden snow goggles to

reduce snow blindness about two thousand years ago.  These had two wide,

narrow, horizontal slits which allowed good horizontal vision but reduced

direct and reflected sunlight.  If the slits alone don't rduce the light

enough, you might be able to conceal some lenses from modern sunglasses

beneath them.

Age of Glasses:

R/A: Umberto Eco...maintains (in the NOVEL...Name of the Rose) that

   pince-nez metal glasses, (as opposed to the ones on Henry

   VIII's grotesque helm and featured in Complete Anachronist I)

   were becoming available in the mid 1300s.

IM: Umberto Eco's Pince-nez ("pinched nose") glasses are quite

   similar to Henry VIII's helm (although I haven't seen the

   spectacles in the CA I).  Essentially, we are talking about a

   pair of round lenses on a hinged section. This hinged bit may

   be a small arc, or a longish handle.  A 14th C. pair, similar

   in appearance to those used in the movie "Name of the Rose",

   but made from bone were excavated from the Trig Lane

   excavations in London.  [there are at least 2 articles on this

   topic by Michael Rhodes, one in London Archaeologist 4 (1980),

   23-5; and the other in Antiquaries Journal 62 (1982), 57-73.

   Both are discussed in Arthur McGregor's Bone, Antler, Ivory

   and Horn]

R/A: No, we aren't. King Harry's glasses and the kinds outlined in

   CA 1 are metallic Eco's are "almonds" of glass "mounted in a

   metal fork."

IM: I beg to differ. Brother William's Spectacles are described as

   "...It was a forked pin, so constructed that it could stay on

   a man's nose ... as a rider remains astride his horse or as a

   bird clings to its perch. And, one on either side of the fork,

   there were two ovals of metal, which held two almonds of

   glass, thick as the bottom of a tumbler. ..." (p.74 of the

   1983 Harcourt Brace and Jovanovich edition)

   The twin ovals of metal, one on either side of a fork sound to

   me to be very like the versions used in the movie, and that I

   have heretofore described.

IM Unfortunately, while Henry VIII is technically "period", he is

   not period for me. The earliest I can shove the documentation

   for spectacles to is c1285, and that's based on a reference in

   a sermon in 1305 that they've been around for 20 years. At

   best, it's still 160 years later than I need for my current

   persona.

   In my brand new copy of Ancient Inventions by Peter James and

   Nick Thorpe there is a discussion on Spectacles (pp.289-295)

   [using as IT's major source, E. Rosen., "Invention of

   Eyeglasses," Journal of the History of Medicine 11 (Jan 1956),

   pp.13-46; (April 1956), pp 183-218), which I have not, as yet,

   seen].

   It describes (as well as shows) a fresco by Tommaso di Modena,

   painted in 1352 showing a pair of spectacles with the curved

   hinge/nose-piece. There is also a mention of a sermon by a

   Dominican Friar Giordano da Rivalto deleivered in 1305,

   reporting that 20 years before, a man the good friar had

   actually met, had invented the spectacles. Unfortunately, this

   is an area wherein a lot of hoaxes have been perpetrated (and

   to be honest, since this is, at best, a fourth-hand source, I

   will take it as merely an interesting hypothesis until I can

   backtrack the documentation).

 

   Respected friend, would India in the 900's be any use to you?

   One of my costume books has a miniature of a hindu scholar

   wearing some very eyglass-like corrective lenses... Then

   again, they're almost certainly either rock crystal or smoky

   topaz, thus not "Glasses" atall, atall...

 

lescoxwell at delphi.com (Les Coxwell):

   It seems that the 1285 date for spectacles is likely to be the

   earliest date. Regulations from the Venetian Glassmakers'

   Guild which refers to spectacle lenses dates from about 1300

   and would seem to confirm the date. However, a number of

   rock-crytal lenses have been found around the Mediterranean,

   including Turkey and Crete, and seem to date from various

   periods befor the second century AD. Although there seems to

   be no evidence for them having been fitted into spectacles,

   there is no evidence that says that they were not.

   A reference in a Chinese work, previously thought to date from

   about    1240 AD, is now believed to date from sometime after

   1410. It referred to a gift of spectacles to the Emperor of

   China from the King of Malacca, on the Malaysian peninsula,

   and this is also referred to in some court records which have

   been positively dated to 1410.

 

Shape of Lenses:

D/A BUT: a problem - the glasses were reading glasses for the

   far-sighted. Several people in society maintain that glasses

   for the nearsighted were a later development....[deletia]....

IM OTOH, This same nifty new tome (Ancient Inventions by Peter

   James and Nick Thorpe) as a section on Magnifying lenses

   (pp.157-161), in which it repeats the old from Pliny about

   Nero's "smaragdus", which is reputed to be "Concave in shape,

   so that it concentrates the vision". Ie., a lens for us

   myopics.

 

Sunglasses:

   Baking Linseed Oil on glass:

   Stained Glass:

lescoxwell at delphi.com (Les Coxwell):

   OTOH, Aleksandr, your sunglasses may actually be available

   earlier, if you can establish Chinese connection through

   trade. There is a refernce to Judges wearimg dark glasses made

   of smoky quartz, not as a protection against the sun but to

   disguise their reactions to evidence read out to them in

   court.

   As an alternative the Inuit developed carved ivory or wooden

   snow goggles to reduce snow blindness about two thousand years

   ago. These had two wide, narrow, horizontal slits which

   allowed good horizontal vision but reduced direct and

   reflected sunlight. If the slits alone don't rduce the light

   enough, you might be able to conceal some lenses from modern

   sunglasses beneath them.

  

   Sunglasses are period. Sort of. Anyway, that's what I've read. What

   you do is take regular glasses, paint linseed oil on them, and

   bake'em. The linseed oil turns black; if you did everything correctly,

   you'll still be able to see through the glasses after you're done.

 

IMC:

   I can relate to that. However, should Nero's smaragdus actually

   have been an emerald...

D/A:

   >Anyone with a source of cheap, 3" diameter, optically excellent

   >Emeralds, please contact.....

IMC:   

   The best I can do is suggest a source for false amber

   made from *real* amber blended with some sort of plastic. I've never

   used it myself, but I'm told that it can be worked as easily as real

   amber, and is significantly cheaper. The company makes similar faux

   gemstone plastics from real gems. If you are interested, I'll get the

   address...

Question: were glasses available in your persona's time/place? I haven't

finished the research yet, but citing Umberto Eco (who seems to usually

know what he's talking about in his fiction) metal-framed pince nez's

were available but rare in Europe by the latter part of the 14th

century. (admittedly poor documentation - the reason I haven't made a

pair yet) And the Islamic world was far more advanced in the field of

optics in period.

 

We know that by Henry VIII's day that glasses were available to at least

English royalty, or the brass (substitutiong for bone) frame shown on

the face of his grotesque armor would not be there.

Tamar the Gypsy adds: shortly after _Scientiae Draconis_ in the Middle

Kingdom published articles on period eyewear, Andrew MacRobb got his

optician to make and give him lenses made to fit the wooden frames Andrew

had made.  In fact, tortoise-shell (read: variegated brown plastic) and

metal were used, so wire-rims are okay too.  The earliest glasses (circa

13th century I believe) were the pince-nez-style (actually, had a pivot

screw that held two single-lens-with-handle shapes together), but it

wasn't too long (15th century?) before string loops were added that went

around the ears.  In China, but not in the West, there were strings with

weights on the end that draped over the ears and helped hold the glasses

up. The earliest glasses in the west supposedly were made of smoky

quartz, and therefore grey sunglasses would be allowable.  All the

examples I've seen pictured had round lenses - the classic owl-eyes

look. Also, they tend to be small, so your medieval specs wouldn't be

likely to impress the boss mundanely; they spread among the older

scholars who wanted them to read with.

While browsing through the bargain book section at a local bookstore, I

came upon a book filled with eyewear from all sorts of times in history. I

assume it was published for fashion students, as there was one from the

same company just next to it with hats of all sorts.  

 

In this book, there were photos of glasses from as early as the 14th

Century. These were the actual glasses, not portraits of people wearing

glasses. There were only a handful of photos for "our period," but a lot

of 17th and 18th century  specs.

 

I don't recall the name of the book, but it was something very simple like

Eyeglasses or Eyewear. And, the rims sold by Jas. Townsend & Sons match

the early glasses shown in that book.

   >Also having to deal with eyewear, I did some research, and the

Encyclopedia Britannica has the following:

 

Roger Bacon in 1268 recorded the earliest comment on the optical use of

lenses, but magnifying glasses inserted in frames were used by the Chinese

for reading as early as the 10th century.  Marco Polo noted this custom also

in the court of Kuvlai Khan (1270).  Eyeglasses made their first European

appearance in Italy, their introduction being attributed to Alessandro di

Spina of Florence.  The first portrait to show eyeglasses is that of Hugh of

Provence by Tommaso da Modena, done at Treviso in 1352.  Domenico

Hhirlandajo in 1480 painted St. Jerome at a desk from which dangled

wywglasses, and from this detail St. Jerome became the patron saint of the

spectacle makers' guild.  At first only concave lenses were used for the aid

of presbyopia (old-sight) and hyperopie (old-sight in young people).  A

concave lens for myopia is first evident in the portrait of Pope Leo X,

painted by Raphael in 1517.

 

It also states that transparent quartz and beryl were the first materials

used for lenses, but that the level of demand led to the adoption of optical

glass sometime before 1590, when it was used to make the first Microscope.

(Telescopes weren't invented till 1608, so the spyglass is not period!)

 

Of course, it was still another 100+ years before Ben Franklin invented

bifocals, so I guess my next pair should be the kind with no lines....

I'm in the middle of reading William Harrison's "The Description of

England", published in 1587. In the chapter on metals he mentions

glasses with tin or silver frames. I presume modern steel would be a

reasonable substitute.

 

He also mentions "spectacles set in leather" for use when working with

saffron. The context suggests these are some sort of goggles. Maybe a

set of the soft plastic "sport glasses" covered with cabretta leather?

 

The first option you could presumably do when you buy your next

set--just opt for more period-looking frames. The second option

assumes you have the discretionary funds to have a set of

just-for-fighting glasses made, which I'll grant is unlikely for the

average SCAer. <G>

_Ancient Inventions_ pg. 295: Eskimo snow goggles carved from ivory

between AD 100 and AD 800.  One pair had (small) round holes, the other

had single wide horizontal slits (trapezoidal, wider at the outside).

Quite possibly others had multiple slits.

 

However, as has been posted by others, gray rock crystal (aka smoky

quartz) was used for some early spectacle lenses, and Nero looked at the

gladiators through an emerald lens.  In China, in the early twelfth

century (same source book), smoky quartz glasses were used by judges to

disguise their reactions to evidence being read out in court.

This is an important point- so many people wear them today that even if

ou DO notice them, it's eally easy to tune them out.  No one would

suggest a person not take his medications at a public feast because

they're not period... it's the same with glasses.

This is very admirable, BUT making glasses is much more complicated than

sticking a pair of lens' into anything that will hold them up.  Angle,

focal point and focal length are all important factors- and, most people

are NOT able to calculate these and accurately engineer the glasses to

the specifications.  If your prescription is weak, it may not make a big

difference.. but, with a prescription as strong as mine (or that worn by

the originator of ths thread) it makes a big difference.  It would be

just as bad for my eyes to wear my lens' improperly as it would be not

to wear them at all.

We can do better than that: The Britannica On-line says that magnifying

lenses for reading were used in Europe by the 13th century and probably

before. They would certainly have been luxury items, but they existed.

Greetings to the gentles of the Merryrose,

 

In my search for information on birds in period, I came across a

painting that I also think  has a gentleman wearing spectacles. I need a

second opinion.

 

Anyone with access to a book with the painting of _The Marriage at Cana_

by Paolo Veronese, 1563, Musee du Louvre, Paris, please take a look. On

the extreme right are two pillars and in between the pillars is a

gentleman's head with a receing heairline, beard and no headcovering. Is

this man earing spectacles? In front of him is a servant with a red cap

with white beads.

 

I am looking at the painting in a book called _Great Paintings of the

Western World_ by Gallup, Gruitrooy and Weisburg, Barnes and Noble

Please reply or flame privately.  Thank you.

I ran across a couple of refs to myself in the floralegium on

eyeglasses.

 

One is quite out of date (the one where I, under my former name spelling

of "Nicmaolain" say I've never seen period eyeglasses. Since I am the

"lady in _ shire" with the weighted glasses quoted about in the last

letter, [Wed, 05 Feb 1997 - Stefan] this becomes a nonsequiter of sorts.

 

I would like to somewhat rebut the last letter, BTW, as I did, indeed,

take into account things like focal point and length in making mine. In

fact, the Creative Anachronist issue #1 that inspired me makes quite a

point of what is involved in setting up the lenses properly.

 

If a person feels their prescription is too complex for home experiment,

then by all means they should talk to a professional. But for many of

us, all we'll get out of a failed experimant is a slight headache and a

lot of new learning. After all, if your new "old" glasses don't fit, no

one can force you to wear them!  :-) And, as CA #1 says, with some input

on both sides, you can make your own frames and get your optometrist to

make lenses for them, in which case all s\he has to do is clearly mark

how to install them, so you won't get them "wrong side to" or upside

down.

The spectacles sold by Jason Townsend are modeled on the pair

from about the middle of the 15th C. found in Trig Lane, London

in the 1974-5 excavations, the deposits ended about 1440. I bought

the original magazine this winter in a batch from England.

 

London Archaeologist Magazine: ISSN 00245984

      Published Quarterly by the London Archaeologist Association,

      7 Coalcroft Road, S.W. 15, London. (At least then.)

Winter 1980, Vol. 4, No. 1

**A Pair of Late Medieval Spectacles from the Trig Lane Site

      by Michael Rhodes pp. 23-5 including three illustrations:

        the original pair, a detailed measured view, and a suggested

      wearing position on a face. Discusses the manufacture methods.

century and came originally from Venice. By the 1400's they

were being imported into England. By the 1500's they were being

imported in large numbers. Most of the importing ships were

Dutch. The first spectacle maker recorded in England was Paul

van (de) Bessen of 'S_uthwark' (no O) in 1459-9.

The Worhipful Company of Spectacle Makers of London dates to

1629, and was modelled on the Dutch companies.

 

The Trig Lane spectacles are said to be the earliest securely

dated spectacles in Europe (at least at the time of publication).

 

The only other earlier sets stated found are from the Convent

of Wienhausen in Germany where they found 11 pairs, two of

which match the London example. All were of wood. These I

have no pictures of.

 

The frames are identical and the only bone large enough in

medieval times was the Metacarpal bone of a bull.

Each side is 2.5mm thick and held a lens of about 30mm.

The circular parts were cut using a specially adapted pair

of dividers. They had an iron rivet with a metal washer on

either side. The literal split (not cut) enabling the lens

to be inserted has three teeth protruding on each side and

is secured by fine copper wires running around the teeth.

The lenses fit in incised V grooves in the frames.

...........

I too have the Compleat Anachronist I on Spectacles.

...........

I also have _A Spectacle of Spectacles_, Carl-Zeiss-Stiftung Jena,

which is the 1988-89 exhibition catalog from the National

Museum of Scotland in Edinburgh. Hardback, Edition Leipzig.

178 pp., 108 illustrated examples from western and eastern

cultures 1400-1900, ISBN 3361002508.

 

Only about a dozen pictures illustrate pre-1600 period glasses.

 

The first is an iron rivetted folding pair from about 1400 AD

which has no spit seams at all for admitting the lenses.

They are a simple wide circle each side with a straight

metal strip running to a slightly larger circle centered where

it rivets both identical sides, provenance unstated. Three

pieces total, two identical sides, one rivet, no lenses.

There appears to be a groove for holding the lens.

I wonder if perhaps they heated the rims to expand and contract

back on the lenses' edges.

 

The next pairs illustrated are made of leather, bone, and

bone, then horn, then brass, all 16th century. The Trig

Lane set is not even mentioned.

 

The actual invention of eyeglasses is attributed to an

unnamed glass worker of Pisa about 1286. Earliest lenses

were convex until about the mid fifteenth century when

concave lenses were invented. Earliest regulations on the

manufacture of lenses is 1300 in Venice.

 

I bought my copy a year or so ago. Probably from either

Edward R. Hamilton Bookseller or Scholars Bookshelf, or

Hacker Art Books, all of which are on the web. I think it

was about twenty dollars. Probably still selling them.

............

Somewhere I also have what I remember to be a Smithsonian

article on spectacles. I had thought it was carefully

placed in either a book or an assembly of costume articles.

Today it just isn't jumping out of my stacks at me.

............

And I know that in my art books are probably dozens

of pictures of late period spectacles. With the large

amount of those I have I don't have time to delve further

today. And one of these days I may get around to shifting

the numerous articles, pictures, and copies into more

usable form. Right now that stack would be about eight

feet high, not counting the thirty drawer chests I use

and the fifty + binders.

 

Hope this helps someone.

You can buy a bone set from 1440 from http://www.Jastown.com/

It simulates the Trig Lane pair. They are the only ones I

know of being made.

 

Or you can ILL or buy the book or article I cited / or get the

Compleat Anachronist #1 mentioned from the www.sca.org stock clerk,

find a metalsmith and have a pair made up.

 

The earliest pair I have a picture of had frames that looked

about 5/16" wide around the circular glass in iron, and probably

3/16" thick. They were joined at the center by a rivet in two

matching round ends pivoting over the nose. Imagine two really

wide iron pan frames with wide handles and wider round handle

ends, with a groove to hold the circular lenses. There was no

split in this pair to allow for lens insertion and it did not

appear that there was a rabbet/rebate on the back side to allow

for lens insertion and gluing/puttying in place, only a shallow

vee groove.

 

Not a whole lot more I can do from this end. Being disabled

I rarely see a copier and I'm not breaking copyright laws

posting it on the net. Look at religious art for ideas.

Lots of the clerics wear glasses in the pictures.

 

Generally, I've found if I want something bad enough I can do it

slowly myself and end up with a superior product to what I

can often buy.

 

It shouldn't be too hard to get some material at a scrapyard,

they have brass and bronze here as well at them, or some bones

from a pet store as I do, and use a metal blade in a coping

saw / jeweller's saw frame, to saw a pair of frames out.

 

I'd take a file or appropriately hard metal piece and grind

the edge of it to use as a scraper to cut the inside Vee in

the lense frames with a tooth appropriately ground/shaped

and a shoulder on the file edge for it to ride on the outside

face of the metal as you scrape the groove.

__________________

   old file end   \ with appropriate tooth scraper ground.

          _  _____|

_________| \/ |

shoulder |    |<=== inside of frame being scraped.

with smooth edges

 

A flat/round sided file should clean up the rest of the frame.

Then rivet it. Of course you would need a pair of dividers /

compass to do the basic layout. So only a handful of tools at most.

 

The theory was the bone frame circles were cut with a toothed

cutter on some dividers or similar rotating tools with center

pivots and cutting edges. This could be a double ended flat

piece of metal with centers and cutters at different distances

for the inside/outside of the lens frame. Something harder

than the material you want to cut, which is the universal rule

for cutting/abrading anything.

 

You'd be surprised at what you can do if you try hard enough.

 

Besides, difficult materials give you lots of time to work

with them and minimize mistakes/make adjustments. Cut to

the outside of your line, file/sand carefully to the line.

 

I do engraving and carving in bone and many other materials

with hand tools. Before becoming disabled permanently I was

a modelmaker, did machining, furniture, cabinets, woodwork

and plastic work of all descriptions, and now muck about with

jewellery, enamelling and bonework when my muscle knots allow.

I have advanced FMS. I could do industrial models to half a

thousandth's of an inch by hand. This is not an exageration.

 

Like most things one does, it's all how you approach the material,

the least successful do the least mental preparation to the craft.

Consider carefully, and plan ahead as you do it.

I could cut a whole set of different cabinets out at once with

a little forethought.

 

I imagine though that you might have to use a good

optical worker to shape your outside vee on some old glass

lenses. I may do the same thing myself at some point.

My problem is I like earlier periods, and can't wear contacts

due to a viral infection/injury that left both eyes too dry.

Hi, Lucia. I just came back from a research trip. I was looking in oldcopiesof Post-Medieval Archaeology, and I found the finds listing from theFreeGrammar School at the Whitefriars, Coventry, dated 1545-1557/8. There isaset of frames for spectacles in the finds. It is of a copper alloy(probablybrass), and consists of a u shaped channel bent into two circles, with adecorative bridge and two couplers attached at the gap in the u-channeltoclose the ring with a rivet. The lenses are not there, sadly, but thedrawingshows an approximately 11/4 in lense size. The lenses are, of course,round.Do you have any jewelry making friends who might know a good jewelryfindssupplier (There are a few in Phila., I use Hagstoz)? They could find theu-channel and tubing, and probably file up the bridge. You could alsolook onthe web, there are a few optometrists that cater to the reenactmentcommunity, and will make round lenses. It is one of my giant list ofthingsto do for myself, but since I can wear contacts, I haven't worked toohard :)

However, someone making such a range of period spectacles is bound

to be of note. Previously all I've heard of is the Trig Lane spectacle

reproduction frames (circa 1440) being sold by http://www.jastown.com/ .

As it's a new direction for him and for non-optometrical reenactors

in general, it's simply worth making a note of.

 

Just think, you can finally look authentic in that nifty late period

Elizabethan overmess on a hundred and five degree F. Pennsic day -

melted or not. ;)

 

I'm an earlier perioder myself. Unfortunately glasses date to around

1275 in Venice. Vikings only had burning or jewelry fine-detail lenses.

For that article you'd have to have been an earlier subscriber to

Viking Heritage Magazine from Sweden (Gotland actually). Same general

folks the Viking Beads CD comes from.  http://frojel.hgo.se/

What I've done, and will continue to do, it use my last pair of lenses,

which are usually nearly OK for normal use - a bit scratched, and only a

little, or not at all, off my current prescription. I then get the optical

people to reshape them for my reenactment lenses - last time it cost me

under AUS$20 (about the cost of a main meal at an average restaurant here).

The frames are leather, hand-made by my husband, held on by cord, so it was

a fairly cheap exercise. Next time I get new lenses (which has to be before

the end of this year), I'll do the same, and upgrade to a pair of pewter

frames held by cord, as we've started doing pewterwork at home.

 

A couple of friends of mine have chosen their frames carefully - brushed

silver metal frames with round lenses, for their everyday glasses, so they

can wear them at reenactment events without looking odd, and not need two

pairs.

Lets examine this a little closer ...

 

Robert Grosseteste (1175-1253) was Roger Bacon's mentor;

first chancellor of Oxford; knew the earth was round;

declared that the sphericity of the earth, as of all

stars and planets was proved by natural reason and

astronomical experience; he believed it was impossible

to understand the physical world without mathematics; he

believed that light was the first corporal form ... that

the characteristic property of light was its ability to

propagate itself instantaneously in straight lines in

all directions without loss of substance and that is this

way light had generated the universe ... on these grounds,

Grosseteste believed that the study of optics was the key

to understanding the physical world.

 

The study of optics led Grosseteste to suggest the use of

lenses for the purpose of magnification:

 

For this branch of Perspective thoroughly known shows us

how to make things very far off seem very close at hand ...

and how to make distant objects appear as large as we

choose, so that it is possible for us to read the smallest

letters at an incredible distance or to count sand, or

grain, or grass, or any other minute objects.  [14]

 

[14] quoted in L. Thorndike, "A History of Magic and Science"

 

>> Correcting lens eye wear came into use a few decades

>> after Roger Bacon (1214-1292) did work on optics --

>> especially ray tracing based on a dissected cow eye.

 

Jean Gimpel; "Medieval Machine"

 

My reference doesn't say when Grosseteste made his comments

about seeing small letters, counting sand, etc. -- it does

indicate that Grosseteste's reasoning on optics preceded

Roger Bacon's work -- but not when.

 

Even though the lives of your persona and Grosseteste do

overlap, his work may not be early enough for your use.

... But we should check for that date -- I wonder where?

 

I am still in awe of what you are doing to create your

persona.

Subject: [Bryn-gwlad] reading stones

 

Reading stones--hemispherical pieces of of beryl, glass, or quartz that, when laid upon the page, magnify text and images--were in popular use in Western Europe beginning some time between 1000 and 1250 C.E. and at least until spectacles became widely available.  They were especially useful for near-sighted readers and for people who spent long hours pouring over tiny script, and were often found in a scribe's tool box.  You can see three photos of reading stones on the Antique Spectacles and Other Vision Aids site.  One is of a reproduction in the collection of the Zeiss Optical Museum <http://www.antiquespectacles.com/history/reading_stone.htm>;.  The source of the others <http://www.antiquespectacles.com/statements/1600.htm>; isn't specified.

 

I'm mentioning this because Half Price Books <http://www.halfpricebooks.com/>; currently has acrylic dome magnifiers <http://www.domemagnifier.com/>; for sale for $5 each (not counting the 20% discount available through Monday, September 1st because of their Labor Day sale).  I suspect they're bigger than medieval reading stones (though I haven't been able to find any information on the dimensions of those); they're roughly two inches in diameter, and almost an inch and a half tall.  And they're not strictly hemispherical, but rather squat cylinders with hemispherical tops.  But they do resemble reading stones, and are certainly less obtrusive than many magnifying options.  If you find yourself using books at events and want something "perioid" to use when you need to get a better look at something, it's an option.  They offer 4X magnification.

 

Dome magnifiers are, of course, available elsewhere.  I've seen them at book stores and embroidery stores, as well as online.  But they're usually more than twice what Half Price is charging, and I thought someone in the Barony might benefit from the sale.

Mistress Elspet made me a set of magnifying glasses: round glass balls that when filled with water can be used separately or together to magnify an object. Supposedly they can also be used together to form a sort of early period telescope, but I haven't had a LOT of success with that (my own eyes seem to do a better job, smile). Folks seem to love playing with them & they were a big hit with the kids at our last Boy Scout demo.

Does anyone have or know a resource for renaissance eyeglasses? My Walmart specials clash with my doublet and muffin top hat. Thank you.

Maybe a bit early for you, ca1490.

I hadn't seen those. The ones I've seen have been scissor or spring style. My persona is 1520s-40s, clothing styles overlapped so I think those would work.

Yeah, thread loop specs are on my list of wants, would keep them in place during combat. My optician has offered to make me up a set if I cross his palm with much silver. Not having nose pads would be the biggest problem I think.

I wonder if taking the legs off a round frame and replacing them with string will work, at least for the interim.

Good idea, tho' I think the thin elastic hat cord would work better than string.

And if you are looking for completed glasses or frames instead of sources from which to make your own, there are a number of makers selling them on Etsy, and at least one has sized them so that stock lenses (in your prescription) from a certain online glasses dealer will fit. A search for 'medieval eyeglasses' should turn them up.

I like this article: http://www.antiquespectacles.com/history/ages/through_the_ages.htm

 

I think catches the bull by the horns:

 

"But it was definitely the city of Florence that by the middle of the fifteenth century led in innovation, production, sale, and spread of spectacles within and outside Italy as attested by documents already or soon to be published. In particular, Published evidence in the form of letters of the dukes of Milan, Francesco and Galeazzo Maria Sforza, dated 1462 and 1466 respectively, reveal the first detailed information about spectacles since their invention; namely, 1. Florence was producing in large quantities not only convex lenses for presbyopes, but also concave (diverging) lenses for myopes (i. e., about a half century before the latter were thought to have been developed); 2. Florence had become the leading manufacturer of readily available and affordable good-quality spectacles; 3. Florentine spectacle makers were well aware of the fact that visual acuity declines gradually after the age of thirty, and were constructing lenses progressively graded in five-year strengths for hyperopes or presbyopes and in two strengths for myopes, practically prescription lenses; 4. The dukes of Milan were ordering prestigious Florentine glasses by the hundreds to give them away as gifts to their courtiers, the first record of such a phenomenon in the literature. The massive documentation available only in Florence for this early period has revealed the name of fifty-two spectacle makers between 1413 and 1562 and the location of their shops. The large numbers of spectacles circulating in northwest Europe (especially London) from the 14th century were being mass produced in the Low Countries. They were then manufactured in England beginning in the 15th century. Other centers of production like Germany, France, and Netherlands began to appear more frequently in the sources only by the sixteenth century but they never produced anything near the quantity of the Florentine documentation until well into the seventeenth century. The documents from Florence and other places will be discussed along with archeological evidence recently discovered in various digs in Europe in the forthcoming book, "Renaissance Vision from Spectacles to Telescopes," by Vincent Ilardi". (Translations of the two key 1460's letters)

 

I wrote:

<< I have never documented my findings on magnifying glasses for the farsighted but my gut feeling from my investigations during the 15th century is that they were available. I think they were available from the times of la Celestina and have asked my colleagues what info they might have. Actually it is perfectly logical that lenses were available from the 8th century in Cordoba when the crystal factory was founded to provide crystal wine glasses to the court thanks to Ziryab's contributions to refined living in Andalusia. >>

424 BCE?  That will be a a burning glass mentioned in Aristophanes "The Cloud." That makes it a bi-convex lens, probably of glass but possibly of rock crystal.  The earliest known lens in the Layard lens, Assyrian rock crystal from roughly 1000 BCE.

 

A source that I really would like to see on this subject is Vincent Ilardi, Renaissance Vision from Spectacles to Telescopes from the American Philosophical Society.

Try

for the Layard or Nimrud lens.  Most of the other lenses are simply

descriptions in various texts until the 15th Century paintings.

To the first question, it's why I want to read the book by Ilardi.  It's an American Philosophical Society monograph and they are usually very complete.

 

Once you have high quality glass (which the Venetians were doing in the 15th Century), the problem is not carving the lenses, it's making them conform, however roughly, to the problems of the eye.  Magnifying glasses are fairly simple to make (which is why reading glasses are cheap and OTC) reasonably accurate corrective lenses aren't.  I would think this would have been a trial and error process with a lot of rules of thumb, but it's worth noting Newton describes the optical properties of lenses in the 17th Century.

This is the first I've heard of concave lenses within our period, at all.

Like Urtatim, this comes as a surprise to me. Interesting, but I think I'll hold it with a bit of skepticism until I see some more supporting evidence. Bear? Seen or heard of these letters?

 

I don't see that it is that more difficult to carve concave lenses if you can do convex ones. You mainly need the idea and reason to do so. Getting the clear, consistent glass is the biggest problem.

Pardon, I have been reminded that Newton's Opticks is about the properties of light in lenses, mirrors and prisms.  The seminal work of optical geometry is the Kitab al Manazir, Book of Optics, by Abu Ali al-Hasan ibn al-Hasan ibn al-Haytham (AKA Alhazen) in the early 11th Century.  A Latin translation was published in Italy in the 16th Century.  Now back to my reading about peppers.

<<< One final concern I have over boffer tournaments is eye safety.

 

Generally, it would be difficult for kids to cause permanent injury with a boffer weapons, but I see the eyes as a weak point.

 

I'd be happier if we required safety glasses for kids involved in boffer combat. I know it's a step away from authenticity, but we're talking about eyes (I can certainly envisage combination leather /perforated steel goggle that would also do the trick, but clear safety glasses are cheap).

Regarding eye safety, if we painted black or gold rims around them, I think we're good.

 

Here is a page of glasses stuff - there are a lot more period eyeglasses than people think.

I've also been playing with safety glasses and PET bottles for German single dagger work, as furniture smashing into wrist bones isnt my idea of

a good time.
