After Athena was born fully armed from Zeus' forehead, Triton, acting as a foster parent to the goddess, raised her alongside his daughter, Pallas. The sea god taught both girls the arts of war. Pallas and Athena were childhood friends, but Athena accidentally killed her during a friendly sparring match. Distraught over what she had done, Athena took the name Pallas for herself as a sign of grief. She became the virgin goddess of wisdom, practical skills, and prudent warfare. Roman counterpart: Minerva.
