Thyne Oldest Known Tech Manual

Posted by timothy on from the better-than-many-current-ones dept.

johnshirley writes "How old is the oldest known technical manual? About 613 years, it seems. Written in 1391 by Geoffrey Chaucer for his ten year old son Lewis (Lowys), the manual explains in great detail but very rough spelling and grammar, the intricate workings of the Astrolabe--the predecessor to the sextant. Read Chaucer's 'A Treatise on the Astrolabe here."

    There was no standardized spelling in Middle English. Different spellings of the same word in the same text are actually very common in writings of this era. Part of it has to do with spacing - a word would be spelled differently so that it would fit into a line better. Pronunciation and vocabulary were not fully standardized in this era either, causing a lot of problems.
