The Librarian Who Measured the Earth

“More than two thousand years ago, a very smart baby was born. His name was Eratosthenes.”

Eratosthenes was full of curiosity, questions, and eagerness to learn, which gave him all kinds of opportunities and led him to exciting places such as the famous library of Alexandria. Here it was that Eratosthenes tackled one of his biggest questions- “How big around is the earth?” Was it even possible to know? Eratosthenes didn’t give up until he found a way.

Based on what we know of the life of Eratosthenes, Katherine Lasky gives us a fascinating picture of the life of the ‘Librarian who measured the earth’.
