OCELLUS the LUCANIAN, an ancient Greek philosopher of the school of Pythagoras, who lived before Plato. His work πῦρ τῶν ἡνιχῶν, or the Universe, is the only production of his which has come down entire to us; it was written originally in the Doric dialect, but has been translated by another hand into the Attic. William Christian, and after him Louis Nogarola, translated this work into Latin; and there are several editions of it, both in Greek and in Latin.
