The names for the planets in the Western world are derived from the naming practices of the Romans, which ultimately derive from those of the Greeks and the Babylonians. In ancient Greece, the two great luminaries the Sun and the Moon were called "Helios" and "Selene"; the farthest planet (Saturn) was called "Phainon", the shiner; followed by "Phaethon" (Jupiter), "bright"; the red planet (Mars) was known as "Pyroeis", the "fiery"; the brightest (Venus) was known as "Phosphoros", the light bringer; and the fleeting final planet (Mercury) was called "Stilbon", the gleamer. The Greeks also made each planet sacred to one among their pantheon of gods, the Olympians: Helios and Selene were the names of both planets and gods; Phainon was sacred to Cronus, the Titan who fathered the Olympians; Phaethon was sacred to Zeus, Cronus's son who deposed him as king; Pyroeis was given to Ares, son of Zeus and god of war; Phosphoros was ruled by Aphrodite, the goddess of love; and Hermes, messenger of the gods and god of learning and wit, ruled over Stilbon.
