Only fragmentary evidence has survived about the life of Eratosthenes, but it is generally accepted that he was born in the city of Cyrene, in Libya, in about B. His father, Aglaus, encouraged him to study in Alexandria, which at that time was the greatest center of learning in North Africa. He was taught by the great grammar tutor, Callimachus, and began to learn philosophy from the likes of Ariston of the Stoic school and Arcesilaus the Academician.

Having excelled at his studies, his abilities were noticed by King Ptolemy III Eurergetes, who commanded him to continue working in the city, replacing none other than Callimachus as the Chief Librarian at the Great Library. He quickly became known as one of the most learned scholars in Alexandria, producing works on a wide variety of subjects. He effectively invented geography as a scientific discipline, producing a map which showed both parallels and meridians for the first time.

He produced two books of mathematics, although these have been lost since ancient times.
