Pallas (daughter of Triton)

In Greek mythology, Pallas (/ˈpæl əs/ ) (Greek: Παλλάς) was the daughter of Triton. Acting as a foster parent to Zeus’s daughter Athena, Triton raised her alongside his own daughter. During a friendly fight between the two goddesses, Athena was protected from harm by Zeus but Pallas was mortally wounded. Out of sadness and regret, she created the palladium, a statue in the likeness of Pallas.[1] This story inspired a yearly festival in Libya dedicated to Athena. Girls from the Machlyans and Auseans tribes would fight each other, and those who died were labeled false virgins.[2]
