Born around 570 BCE in Colophon, Ionia, Xenophanes left his city after Persian conquest and spent much of his long life as a traveling poet-philosopher in Greek colonies of Sicily and southern Italy. He recited elegies at symposia, criticizing Homer and Hesiod for attributing theft and adultery to the gods and arguing that if cattle could paint, they would depict gods as cattle.

Xenophanes proposed a single supreme god unlike mortals in body or mind—'all eye, all mind, all ear'—who moves all things by thought alone. This theological critique anticipated later philosophical monotheism and scientific naturalism. He also observed fossilized shells inland and inferred that land once lay under sea, offering an early geological insight.

Though none of his works survive complete, fragments quoted by later authors reveal a thinker who bridged poetry and philosophy. He influenced the Eleatic school, especially Parmenides, and his attacks on divine anthropomorphism resonated through Socrates, Plato, and the Western tradition of rational religion.
