Named for the Greek philosopher Xenophanes of Colophon (570–475 B.C.). He was in the first place a poet, using poetry to express his reflections about philosophical problems. Although he continued the tradition of Ionic philosophy (e.g., on nature), he spent much of his time attacking the idea of anthropomorphic gods, such as we know them from the work of Homer {see planet  (5700)} and Hesiod. From this the idea of a more abstract god, in combination with ethic principles, has been evolved. Much later, Plato {see planet  (5451)} took up this picture. However, the great achievement of Xenophanes remains his introduction of reflection on knowledge into philosophy. (M 24918) Xenophanes is also honored by a lunar crater. _ _.
