One place to start would be the History of Navigation section of _The

American Practical Navigator_ by Nathaniel Bowditch.  The edition I

have is the 1967, but the work has been kept in print by the US Navy

since 1867 (the book--in it's original form--actually goes back to

1803).

If you are talking about Sextants (as in navigation), there are plenty of

books on sailing, navigation, and such.

If you are interested for SCA purposes, keep in mind that sextants are a

little too late, even by the 1650 limit.  The immediate ancestor of the

sextant is the Backstaff, which looks somewhat similar but is much larger

and works in a slightly different way.  I just saw a bunch of them in the

UK while reseraching astrolabes, quadrants, sundials and such. They were

all made by instrument makers, who upgraded their wares with new

technology, much as we are switching to GPS.

 

Have fun

For *period* navigational gear, get ahold of "Chaucer [yes,the Goeffrey

Chaucer] on the Astrolabe with Original Illustrations" available in

Middle English or a 1931 Modern English edition published by Oxford

University Press or the revised edition (1977) self-published by Norman

Greene (Box 7657/ Berkeley, Ca. 94707 or (415) 524-1109)) He may (if in

a good mood) offer to sell you some of his reconstructions which, though

accurate, are expensive.

 

If you happen to find an original Middle English first edition printed

by Caxton, I'll be only too glad to trade it for a modern translation

<sick grin>

 

Seriously, the ME may be available on the Web either through The Chaucer

Project or Project Gutenberg as the copyright has long expired.

 

Also I *think* the Gies's Cathedral, Forge and Waterwheel makes mention

of early navigational instruments, as do several episodes of James

Glenk's Connections broadcast every month or so on The Learning Channel.

Both of the above are purely secondary sources, but hey...

Of course, the sextant was not used intil very late if at all in period. Aleksandr has given the best advice in looking up Chaucer on the astrolabe, which was the chief method of determining latitude in later period. Another instrument of navigation which is quite easy to recreate is the "Jacob's ladder" which consisted of a marked stick with a sliding crosspiece which was used for making sightings.  And, of course, longitude simply could not be determined in period and was not accurately determined until the refinement of an accurate chronometer.

Given that the SCA's period stretches from the end of the Roman

_classes_ to the Great Armada, the question of navigation isn't

an easy one to answer. My own research has mostly concentrated on

the Age of Exploration, and even more specifically on the voyages

and voyagers of the Iberian Peninsula, more on Portugal than on

Aragon or Castile.

 

A fair introductory work to the entire sweep of mediaeval

seafaring was written by the late Archibald Lewis. IMO, his

European Naval and Maritime History belongs in every college

library, and mine, too, if I can find a way to get it cheaply.

 

If you wish to look into my half-acre of maritime history, you're

more than welcome! Start with Hale's Renaissance Exploration, and

Parry's Age of Reconnaisance, and Brown's Story of Maps. Samuel

Eliot Morison's Admiral of the Ocean Sea, while focussing on

Cristobal Colon, is also a worthy work to keep near at hand, for

Morison was a yachtsman, and sailed many of the same seas that

Colon did.

There is a fairly recent book called "Latitude Hooks and Azmuth Rings" which

discussed how to build working replicas of early navigation instruments. There

are a few primitive tools, but most are 1500 and later. I don't have the

author or ISBN of the book handy, but can supply it if necessary.
