**Euclid** (ca 300 B.C.) was a Greek mathematician, who
appears to have been educated in Athens by pupils of Plato. Euclid
later founded a school of mathematics in Alexandria.

His major work is the *Elements*, a 13–volume work on
mathematics. Many other books have been attributed to Euclid, but
with some disagreement among historians as to their actual
authorship. These include the *Division of the Scale*, a
discussion of music in mathematical terms, and *Data*, a
presentation of geometric theorems. Euclid’s *Elements*
remained a major text for some 2000 years, and some sections are
still used today for high school teaching of plane geometry. (Can
you imagine writing a textbook that is still in use 2000 years
later?)
