The Greek natural philosopher Democritus (ca. 494-ca. 404 B.C.) promulgated the atomic theory, which asserted that the universe is composed of two elements: the atoms and the void in which they exist and move. Democritus was born in Abdera, the leading Greek city on the northern coast of the Aegean Sea. Although the ancient accounts of Democritus's career differ widely, they all agree that he lived to a ripe old age, 90 being the lowest figure.
