Crius

Crius, or Kreios, Krios, was one of the Titans in the list given in Hesiod's Theogony, a son of Uranus and Gaia. The least individualized among the Titans, he was overthrown in the Titanomachy.

Consorting with Eurybia, he fathered Astraeus, Perses, and Pallas. The joining of Astraeus with Eos, brought forth Eosphoros, the stars and the Anemoi.

Joined to fill out lists of Titans to form a total that made a match with the twelve Olympians, Crius was inexorably involved in the ten-year-long war between the Olympian gods and Titans, the Titanomachy, though without any specific part to play. When the war was lost, Crius was banished along with the others to the lower level of Hades, called Tartarus. From his chthonic position in the Underworld, no classical association with Aries, the "Ram" of the zodiac, is ordinarily made.

Aries is the first visible constellation in the sky at the spring season, marking the start of the new year in the ancient Greek calendar. This fact may have implied that Crius was the Titan god of constellations, measuring the duration of the year while his brother, Hyperion, measured the days and months.
