Ocellus Lucanus in a XIX century depiction

Ocellus Lucanus, a Pythagorean philosopher, born in Lucania in the 6th century BC, was perhaps a pupil of Pythagoras himself.[1] Archytas, in a letter to Plato, mentioned that he had talked with the descendants of Ocellus[2].

Stobaeus (Ecl. Phys. i. 13) has preserved a fragment of his Περὶ νόμου (if he was really the author) in the Doric dialect, but the only one of his alleged works which is extant is a short treatise in four chapters in the Ionic dialect generally known as On the Nature of the Universe. Excerpts from this are given in Stobaeus (i. 20), but in Doric. It maintains the doctrine that the universe is uncreated and eternal:

"Every nature that has a progression possesses three boundaries and two intervals. The three boundaries are generation, height of being, and end of being; the intervals are progression from generation to height of being, and from height of being to the end of being. But the universe shows no indications of such boundaries and intervals, for we do not perceive it rising into existence, or becoming; nor growing better and greater; nor become less and worse. Rather, it always continues to persist in the same manner, and is perpetually equal and similar to itself."[3]

Ocellus also asserts that the three great divisions of the universe correspond the three kinds of beings—gods, men and daemons; and, finally, that the human race with all its institutions (the family, marriage and the like) must be eternal. It advocates an ascetic mode of life, with a view to the perfect reproduction of the race and its training in all that is noble and beautiful.[1]

(1860); see also Eduard Zeller, History of Greek Philosophy, i. (Eng. trans.), and J de Heyden-Zielewicz in Breslauer philologische Abhandlungen, viii. 3 (1901). There is an English translation (1831) by Thomas Taylor, the Platonist.[1]
