Asteria

Asteria was the daughter of the Titans Coeüs (Coeus) and Phoebe. She was the sister of Leto. Asteria married Perses and became mother of Hecate.

Not long after her brother was imprisoned in Tartarus, Zeus fell in love with her. Zeus chased Phoebe, but she escaped him when she threw herself off a cliff and was turned into a quail.

Some say that she was transformed into the island of Delos, which was originally named after her, Asteria or Ortygia (ortyx means "quail"). When her sister became pregnant by Zeus, Leto was persecuted by Hera. Asteria offered her sister a safe haven to give birth to the twins, Apollo and Artemis.
