Celtine
In Greek mythology, Celtine was the daughter of Bretannus, king of the Celts. She is known for having been one of the consorts of Heracles. Her story, recorded by Parthenius of Nicaea, is as follows.
When Heracles was driving the cattle of Geryones to Greece, he stopped at Bretannus' house. Celtine fell in love with her father's guest and tricked him into consorting with her: she hid away the kine and told Heracles that in order to get the herd back, he had to content her. Heracles, both anxious to bring the cattle safe to Eurystheus and overcome by Celtine's beauty, consented. From their union was born a son Celtus, eponym of the Celts.
