In Greek mythology, Pallas was a son of Crius and Eurybia, husband of Styx. He was the father of Zelus, Nike, Cratos, and Bia (and sometimes, Eos or Selene). Pallas was the god of wisdom.
Pallas was also an epithet for Athena, who was sometimes thought of as Pallas' daughter. In one story, Pallas tried to rape her; she killed him and turned his skin into the aegis.
Aeson was the name of his horse.
In another version, Pallas was the playmate of Athena, a daughter of the god Triton. One day, while Pallas and Athena were sparring, Zeus appeared between them with the aegis and Pallas, in her fear, forgot to parry a blow from Athena. She was killed and Athena mourned her by building a statue in her likeness, the Palladium, and adopting her name.
