This lively picture-book biography begins more than two thousand years ago, when a very smart baby was born in ancient Greece. His name was Eratosthenes. From the time he was a baby, Eratosthenes was full of wonder and questions. Wherever he went as he grew up, and whatever he did, his curiosity and questions propelled him from one discovery to the next. More than anything, however, Eratosthenes wanted to find out how to measure the earth. Everyone knew the earth was round, but no one knew how big around it was. Eratosthenes knew he couldn't walk around the world to measure it, but could he stand in one spot and figure it out? How he did, coming up with a measurement that is only two hundred miles different from our own calculations today, is an inspiring story that is a celebration of curiosity and a tribute to the questing mind.
