(Πρωτογένεια.).

1. A daughter of Deucalion and Pyrrha. (Apollod. 1.7.2.) She was married to Locrus, but had no children ; Zeus, however, who carried her off, became by her, on mount Maenalus in Arcadia, the father of Opus. (Schol. ad Pind. Ol. 9.8.5; Schol. ad Apollon. Rhod. 4.1780.) According to others she was not the mother, but a daughter of Opus. (Schol. ad Pind. l.c.) Endymion also is called a son of Protogeneia. (Conon, Narrat. 14.)
