It works by removing all multiples of 2, 3, 5, 7 and so on. The Sieve is a simple algorithm which works to identify all of the prime numbers up to a certain integer and is very accurate up to about 10 million. Once again, although Eratosthenes’ writings on prime numbers have not survived, we know of what is called the Sieve of Eratosthenes through the writings of Nicomachus. However, in the history of mathematics, Eratosthenes’ greatest contribution is probably his work with prime numbers. Nonetheless, his mechanical solution effectively solved the cube problem. It may have been more impressive had he managed to square the circle, since we still struggle getting that peg into that hole. We also know from the writings of Theon of Smyrna and Eutocius that Eratosthenes solved the problem of duplicating a cube, one of the three major problems in Greek mathematics (squaring a circle, doubling a cube and trisecting an angle). This work studied the basic definitions of arithmetic and geometry and discussed a wide range of topics which even included music, which we know to be the most mathematical of art forms. He wrote a criticism of the mathematics which formed the basis of Plato’s philosophy, which we know about from the writings of Theon of Smyrna. This earned him the nickname “Beta,” because he was thought to be second best at everything. Although exceptional in a wide range of fields, he was never considered to be the best in any one field. He was known primarily as a mathematician working with number theory, geometry and arithmetic.
Regardless, we have been able to glean something of his accomplishments. Most of what remains is in the form of authors’ references to the works of Eratosthenes. Many of Eratosthenes’ works have been lost to history, destroyed with the Library of Alexandria, whether the result of Julius Caesar’s clumsiness or the intolerance of Christians or Muslims. When threatened with total blindness, he starved himself to death in 194 BCE. He was invited back to Alexandria by Ptolemy III Euergetes to tutor his son, and Ptolemy also made Eratosthenes the third chief librarian at the Library of Alexandria. He became a mathematician and scholar, since he was Greek, and I believe philosopher was the only other occupation available. He then moved to Athens to study philosophy under Arcesilaus and Ariston. He studied grammar under Callimachus in Alexandria.
