TITAN was the Titan god of the calendar.
He was probably identified with Helios, who is often simply called Titan, or else with the Titan Atlas, who was often credited with the invention of astronomy and the astral calendar.
|HYPERION ? (Titan is called the brother of Helios) (Pausanias 2.11.5)
Pausanias, Description of Greece 2. 11. 5 (trans. Jones) (Greek travelogue C2nd A.D.) :
"Having crossed the Asopos River again [near Titane, 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)."
