Cyzicos (1)Kyzikos

The son of Aineios and Ainete; ruler of the Doliones who dwelt on a peninsula attached to the Phrygian mainland and jutting into the Propontis (Sea of Marmara).

When Iason (Jason) and the Argonauts chanced to encounter the Doliones, Kyzikos had just celebrated his marriage but left the bridal chamber to greet the illustrious crew of the Argo; after the formalities of hospitality had been observed, the Argonauts continued on their quest for the Golden Fleece and Kyzikos returned to his bride, Kleite (Cleite).

After taking their leave of king Kyzikos, the Argonauts lost their way in the night and contrary winds blew them back to the peninsula; when the Doliones saw the Argo approaching in the night, they mistakenly assumed that they were being invaded by their enemies and attacked the Argonauts in the darkness; Iason (Jason) killed Kyzikos in the heat of battle without realizing who he was fighting.

When the light of day revealed the horrible mistakes both sides had made, the Argonauts and the Doliones mourned the needless death of Kyzikos; Kleite, Kyzikos’ new bride, could not endure the loss of her beloved husband and hanged herself; the nymphs of the grove cried such tears that a fountain formed and was named after Kyzikos’ devoted wife, Kleite.

His name may also be rendered as Kyzikus or Cyzikus.
