In Greek mythology, Pontus was an ancient, pre-Olympian sea-god, one of the Greek primordial deities. Pontus was Gaia's son and has no father; according to the Greek poet Hesiod, he was born without coupling, though according to Hyginus, Pontus is the son of Aether and Gaia.

In Greek mythology, Aether, Æther, Aither, or Ether is the personification of the bright upper sky. According to Hesiod, he was the son of Erebus (Darkness) and Nyx (Night), and the brother of Hemera (Day). In Orphic cosmogony Aether was the offspring of Chronos (Time), and the brother of Chaos and Erebus.
