Description More Information
Lasky pens this colorfully illustrated biography of the Greek philosopher and scientist Eratosthenes, who compiled the first geography book and accurately measured the globe's circumference - in the second century B.C.!!  His measurements proved to have an error of less than 1% - an amazing feat for someone with no computers, no modern equipment, just his knowledge of the sun's movements and local geography.
