The major competing tradition regarding Athena's parentage involves some of her more mysterious epithets: Pallas. A distant archaic separate entity named Pallas is invoked as Athena's father, sister, foster sister, companion, or opponent in battle. Pallas is often a nymph, a daughter of Triton (a sea god), and a childhood friend of Athena.
In every case, Athena kills Pallas, accidentally, and thereby gains the name for herself. In one telling, they practice the arts of war together until one day they have a falling out. As Pallas is about to strike Athena, Zeus intervenes. With Pallas stunned by a blow from Zeus, Athena takes advantage and kills her. Distraught over what she has done, Athena takes the name Pallas for herself.
When Pallas is Athena's father the events, including her birth, are located near a body of water named Triton or Tritonis. When Pallas is Athena's sister or foster-sister, Athena's father or foster-father is Triton, the son and herald of Poseidon. But Athena may be called the daughter of Poseidon and a nymph named Tritonis, without involving Pallas. Likewise, Pallas may be Athena's father or opponent, without involving Triton. On this topic, Walter Burkert says "she is the Pallas of Athens, Pallas Athenaie, just as Hera of Argos is Here Argeie. For the Athenians, Burkert notes, Athena was simply "the Goddess", hç theós, certainly an ancient title.
