Dios

Dios was an ancient Greek philosopher of uncertain date. Certain Pythagorean writings on aesthetics are ascribed to him. Two fragments found in Stobaeus under the title On Beauty (Περὶ καλλονῆς) are written in an artificial Doric Greek (pseudo-Doric), which was popular among pseudonymous Pythagorean authors. Dios's style is perhaps the most archaizing in the Pythagorean corpus. The fragments in Stobaeus come to some thirty lines of prose. They concern "the physical beauty of young men as a source of ". Philosophically, the excerpt is not noticeably Pythagorean.

A wise saying in a Coptic collection is attributed to a certain Dios, described as a student of the legendary Linos of Thrace. He should probably be identified with the obscure Pythagorean. It states simply, "Diligence (μελετή) is everything."
