What happened
Euclid, who taught at Alexandria in Egypt and about whom almost nothing else biographical is known, compiled the Elements around 300 BCE, a work of 13 books that organizes existing Greek and Near Eastern mathematical knowledge into a single logical structure. Books 1 through 6 cover plane geometry, Books 7 through 9 cover number theory, Book 10 covers irrational numbers, and Books 11 through 13 cover three-dimensional geometry. The entire structure rests on five postulates, including that a straight line can be drawn between any two points and that all right angles are equal, plus a short list of common notions, and every subsequent proposition is derived from these through strict deductive proof rather than asserted from authority or measurement. A manuscript of the complete work, copied by Stephen the Clerk for Arethas of Patras in Constantinople in 888 CE, survives today in Oxford's Bodleian Library.
Why it matters
The Elements influenced the development of Western mathematics for more than 2,000 years and is considered one of the most translated, published, and studied books ever produced, remaining in active use as a geometry textbook into the 20th century. Its method, building an entire field from a small set of explicit assumptions through pure logical deduction, became the model that later thinkers in unrelated fields, from Newton's Principia to legal and philosophical systems, deliberately imitated.
How we know
The Elements survives in numerous ancient and medieval manuscript copies, the earliest complete one being the 888 CE Bodleian manuscript, and centuries of continuous transmission, translation into Arabic and Latin, and use as a standard teaching text give historians an unusually well-documented publication history for an ancient work.
