Was Eratosthenes a librarian?

 

Eratosthenes was a librarian and a Greek mathematician, geographer, and astronomer. He was born in Cyrene (in present-day Libya) in 276 BC and served as the chief librarian at the Library of Alexandria in Egypt in the third century BC. The Library of Alexandria was one of the most famous libraries in the ancient world, and it played a crucial role in developing Greek and Roman scholarship.

As a chief librarian, Eratosthenes collected, organized, and preserved the library's vast collection of books and documents. He was also a scholar in his own right and made significant contributions to mathematics, geography, and astronomy. Eratosthenes is best known for his measurement of the Earth's circumference, which he accomplished using a method involving the angle of the sun's rays at different locations. He also developed the concept of latitude and longitude and created a world map based on his extensive geography knowledge.

Eratosthenes' work as a librarian and scholar had a lasting impact on science and scholarship, and he is remembered as one of the greatest thinkers of the ancient world.
