ABSTRACT
Background information on third-century BCE Greek astronomer, philosopher, librarian, poet, geographer and geometrist Eratosthenes of Cyrene is presented. The author reviews how Eratosthenes is best known for making the first scientific calculation of the circumference of the earth. He also developed the Sieve of Eratosthenes, a theorem for finding prime numbers, and he was the first mathematician to create a map of the ancient world containing lines of latitude and longitude. It was Eratosthenes who coined the term "geography" for the study of the earth. Information on Eratosthenes' birth and early life is reviewed.

    In the process of devising better and better sieves for generation of prime numbers, the efforts gradually lead to the classical Sieve of Eratosthenes. The main theme of Sieve of Eratosthenes is that while deciding primality of a positive integer, it is altogether unnecessary to test composite...
