3. A Pythagorean philosopher, of whose personal history nothing is known.
Works
βίον Δεράπεια
He wrote a work entitled βίον Δεράπεια, treating of practical ethics, parts of which are still extant, in the form of a selection, entitled γνωμικὰ ὁμοιώματα, from which we may infer that the whole work must have been of the highest order of excellence.
