The Librarian Who Measured the Earth
Wonderfully illustrated story of Eratosthenes who was born more than two thousand years ago. He was full of wonder and questions. Wherever he went and whatever he did, his curiosity and questions sent him from one discovery to the next.
His measurement of the circumference of the Earth was only two hundred miles different from our own calculations today. Great story about a man who always let his curiosity lead the way.
