Phoebe was one of the Titans, daughter of Uranus and Gaea. She was married to her brother Coeus, with whom she had Asteria (the starry one) and Leto. The Olympians Apollo and Artemis, twin siblings, were the children of Leto; thus, they were often referred to as Phoebus and Phoebe respectively, taking their alternative names from their grandmother. Phoebe was associated with the moon and the Oracle of Delphi, and was considered to be the goddess of prophecy.
Phoebe is also called Phoibe.
