Hyria (mythology)

In Greek mythology, Hyria (Ancient Greek: Ὑρίη) or Hyrie, also called Thyria or Thyrie (Θυρίη) was the Aetolian daughter of Amphinomus and mother, by Apollo, of Cycnus.

Mythology
Hyrie grieved much for her son's death, not knowing he had been transformed into a swan; so she melted away in tears or, as others say, threw herself into a lake (Hyria) and was herself turned into a swan.
