Meaning & History
The meaning of this name as a whole is not entirely certain. The second element is certainly derived from Greek θεος (theos) "god". The first element, however, is where the uncertainty lies. It may have been derived from Greek πείθω (peitho) "to persuade, to convince", but it could also have been derived from Greek πίτυς (pitys) meaning "pine" (also see Pitys). As such, the name Pittheus either means "persuading god" or "pine god". In Greek mythology, Pittheus was a son of Pelops and the grandfather of Theseus.
