TITAN was the younger Titan-god of the calendar of the seasons. He was a brother of the sun-god Helios.
Presumably HYPERION (he was a brother of Helios) (Pausanias 2.11.5)
CLASSICAL LITERATURE QUOTES
Pausanias, Description of Greece 2. 11. 5 (trans. Jones) (Greek travelogue C2nd A.D.) :
"Having crossed the Asopos River again [near Titane in Sikyonia] and reached the summit of the hill, you come to the place where the natives say that Titan first dwelt. They add that he was the brother of Helios (the Sun), and that after him the place got the name Titane. My own view is that he proved clever at observing the seasons of the year and times when the sun increases and ripens seeds and fruits, and for this reason was held to be the brother of Helios (the Sun)."
