Archimedes of Siracuse

Archimedes of Syracuse (287 BC-212 BC) was a Greek mathematician, inventor and astronomer. He is famous for using the method of exhaustion to compute the area of a shape by filling the circle with a polygon of a greater and greater number of sides. He was killed during the second Punic war by a roman soldier which didn't known who he was. Cicero wrote about his visit to Archimedes' tomb, which was surmounted by a sphere inscribed within a cylinder.
