My understanding is that Helios (a Titan) was actually the one who drove the Sun Chariot across the sky every day. But why, then, was Apollo the god of the Sun?
Am I correct in this understanding? Was Apollo (as a son of Zeus) sort of Helios's boss? He could ride the chariot if he wanted to, but he was also free to mate with Daphne, Cyrene and so forth, and otherwise meddle in human affairs, while Helios had to drive the bus every day? Or did it work another way?
