Helius
From Tardis Wiki, the free Doctor Who reference
Helius was an Olympian. He was worshipped by the Greeks as the god of the sun; however, when the Fourth Doctor saw Helius and the moon goddess Selene reporting to Zeus about their progress moving stars and planets across the galaxy, the Doctor wondered "But which sun? Whose moon?" Helius used a flying chariot pulled by two mechanical horses. (COMIC: The Life Bringer!)
