The surviving fragments of the poems of the classical Greek philosopher Xenophanes of Colophon suggest that he held views very similar to those of modern monotheists. His poems harshly criticize the traditional notion of anthropomorphic gods, commenting that "...if cattle and horses and lions had hands or could paint with their hands and create works such as men do... also would depict the gods' shapes and make their bodies of such a sort as the form they themselves have." Instead, Xenophanes declares that there is "...one god, greatest among gods and humans, like mortals neither in form nor in thought." Xenophanes's theology appears to have been monist, but not truly monotheistic in the strictest sense. Although some later philosophers, such as Antisthenes, believed in doctrines similar to those expounded by Xenophanes, his ideas do not appear to have become widely popular.
