Eos (Greek Ἠώς, or Ἕως “dawn”) is, in Greek mythology, the Titan goddess[1] of the dawn, who rose from her home at the edge of Oceanus, the Ocean that surrounds the world, to herald her brother Helios, the sun.
The Greek worship of the dawn as a goddess is believed to be inherited from Indo-European times. The name Eos is cognate to Latin Aurora, to Vedic Ushas.
