When did Eratosthenes live and die? Eratosthenes was born in Cyrene, Shahhat, Libya in 276 BC and died in Alexandria, Egypt in 194 BC. He was an astronomer, mathematician, and geographer, who eventually beca â¦ me the chief librarian at the Library of Alexandria.
Eratosthenes observed that the sun shone directly down a well at high noon on the day of the summer solstice in Syene and that it cast a shadow in Alexandria, directly south of where the well was. To calculate the circumference of the Earth, Eratosthenes measured the angle of the shadow to the Earth.
