Graecus
In Greek mythology, Graecus was the son of Zeus and Pandora, daughter of Deucalion, and the eponym of the Graecians.
According to the Byzantine author John the Lydian, Hesiod, in his Catalogue of Women, states that Graecus is the son of Zeus and Pandora, daughter of Deucalion and Pyrrha, and says, in addition, that he has a brother, Latinus. The Byzantine author Stephanus of Byzantium states that Graecus was a son of Thessalus.
Graecus was the eponym of the Graecians, a group of Hellenic people who lived westwards of the Hellenes mentioned by Homer. The Hellenic peoples collectively came to be known as Graeci in Latin, after the Graecians.
