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 ???

Eyeglasses to correct farsightedness are period.  Nicholas of Cusa is

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

(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".

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.

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.

In the latest Jas. Townsend & Son catalog, they are offering reproduction
"15th Century Spectacle Frames" in the style described.  The price is $60
(you'll have to take it to your optometrist and get lenses made as well)

Their address is Jas. Townsend & Son, Inc.
133 North First Street
P.O. Box 415
Pierceton, IN 46562

They also have a web page at http://www.jastown.com/townsend/

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.

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

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

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.

Subject: Re: [authenticity] Dates for spectacles

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

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

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.

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 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).

Corin >>>

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.
