Justus van Ghent's depiction of Euclid. No likeness or description of Euclid's physical appearance made during his lifetime survives.

Euclid was a Greek mathematician who lived 325-365 B.C. in Hellenistic Alexandria. He was the father of geometry and wrote the Elements which is considered to be one of the most successful mathematics textbooks ever. Euclid's Elements focuses mainly on geometry but also has a small amount of number theory dealing with prime numbers and even perfect numbers.

Other Works

Euclid wrote other works but not all are extant. Other extant works include Euclid's Optics and Data.

In poetry

The poet Edna St. Vincent Millay wrote a sonnet, "Euclid alone has looked on Beauty bare," an appreciation of the intrinsic beauty of mathematics. ^[1]

Vachel Lindsay's poem, Euclid, views him in a less reverential way:

Old Euclid drew a circle
On a sand-beach long ago.
He bounded and enclosed it
With angles thus and so.
His set of solemn greybeards
Nodded and argued much
Of arc and of circumference,
Diameter and such.
A silent child stood by them
From morning until noon
Because they drew such charming
Round pictures of the moon.^[2]
