Measuring the Earth: Eratosthenes and His Celestial Geometry
This biography introduces Eratosthenes whose mathematical approach opened new ways to describe and understand the world. Using mathematics to study the earth, Eratosthenes broke new ground. In his monumental three-volume Geographica, he took a global view of the world. With its title, he coined a new word, geography. His work in chronology, theater criticism, and as director of the Alexandrian library were among the Greeks' valuable contributions to Western learning.

Recommended for gr. 6-9. Good basic history of Eratosthenes and his times (third century BC). The reader will discover what was known about geography during this time and how things like the circumference of the earth were calculated very accurately over two thousand years ago. Eratosthenes was not only a mathematician and geographer, he was also a poet and a librarian at the great library of Alexandria. The book includes a table of contents, index, glossary, further reading and Internet references, timeline and several related activities.
