In Greek mythology, Atlas (; ) was the primordial Titan who held up the celestial spheres. He is also the titan of astronomy and navigation. Although associated with various places, he became commonly identified with the Atlas Mountains in northwest Africa (Modern-day Morocco, Algeria and Tunisia). Atlas was the son of the Titan Iapetus and the Oceanid Asia or Clymene. In contexts where a Titan and a Titaness are assigned each of the seven planetary powers, Atlas is paired with Phoebe and governs the moon. Hyginus emphasises the primordial nature of Atlas by making him the son of Aether and Gaia. The first part of the term Atlantic Ocean refers to “Sea of Atlas”, the term Atlantis refers to “island of Atlas”.
