Alcyoneus (son of Diomos)

In Greek mythology, Alcyoneus (; Ancient Greek: Ἀλκυονεύς, romanized: Alkuoneús, lit. 'kingfisher') is a young and handsome man from Crissa (an ancient Greek city near Delphi), the only son of Diomus and Meganeira. He features in a short myth where he is chosen to be the sacrificial victim for a beast called Sybaris that terrorised Delphi and the surrounding area, a prototypical example of the hero slays a monster and saves a princess tale.
