In ancient cultures, where you find gods with specialized functions, you'll probably find a sun god or goddess. Many are humanoid and ride or drive a vessel of sort across the sky. It may be a boat, a chariot, or a cup. The sun god of the Greeks and Romans rode in a 4-horse (Pyrios, Aeos, Aethon, and Phlegon) chariot.
There may be more than one god of the sun. The Egyptians differentiated among the aspects of the sun, and had several gods associated with it: Khepri for the rising sun, Atum, the setting, and Ra, at noon, who rode across the sky in a solar bark. The Greeks and Romans also had more than one sun god.
You may notice that most sun deities are male and act as counterparts to female moon deities, but don't take this as a given. There are goddesses of the sun just as there are male deities of the moon.
