Ceyx of Trachis

Not to be confused with Ceyx, another figure in Greek mythology, husband of Alcyone.

In Greek mythology, Ceyx (/ˈsiːɪks/; Ancient Greek: Κήϋξ, translit. Kēüx) was a king of Trachis in Thessaly. He received Heracles,^[1] and Heracles's sons later fled to him.^[2] Some accounts make him Amphitryon's nephew, with Heracles building Trachis for him.^[3] Muller supposes that the marriage of Ceyx and his connection with Heracles were the subjects of ancient poems.^[4]

Ceyx befriended Heracles and offered him protection against King Eurystheus. Ceyx's son Hippasus accompanied Heracles on his campaign against King Eurytus of Oechalia, during which Hippasus was slain in battle.^[5] Ceyx was also called the father of Hylas^[6] and Themistonoe, who married King Cycnus^[7]
