* Apollo is the god of the sun, light, music, poetry, prophecy, healing, and more.
* Artemis is the goddess of the moon, hunting, wilderness, childbirth, and protector of young girls.
While they are twins, they represent opposite forces – Apollo the light and warmth of day, and Artemis the cool and dark of night.
Other mythologies have similar twin figures associated with celestial bodies, but Apollo and Artemis are the most well-known.
