Cephalus (son of Deione/Deioneus)

Sumptuous sacrifices for Cephalus and for Procris are required in the inscribed sacred calendar of Thorikos in southern Attica, dating perhaps to the 430s BCE and published from the stone in 1983.

[8] Athenians localised the myth by asserting that Cephalus was married to Procris, a daughter of Erechtheus, an ancient founding-figure of Athens.

Bribed by a golden crown, his wife admitted Pteleon to her bed, and being detected by Cephalus she fled to Minos.

Procris later on came back to Athens, and once reunited with her after an interval of eight years, Cephalus tested her by returning from the hunt in disguise, and managing to seduce her.

[12] In returning and reconciling, Procris brought two magical gifts, an inerrant javelin that never missed its mark, and a hunting hound, Laelaps that always caught its prey.

Procris then conceived doubts about her husband, who left his bride at the bridal chamber[13] and climbed to a mountaintop[14] and sang a hymn invoking Nephele, "cloud".

Cephalus, hearing a stirring in the brush and thinking the noise came from an animal, threw the never-erring javelin in the direction of the sound – and Procris was impaled.

34) in the so-called "Mythographus Homericus"; a papyrus (PBerolinensis 13282) representing a parallel text based on the same source confirms the details.

[16] In a separate episode that is simply an aition explaining the name of Cephallenia and reinforcing its cultural connections with Athens,[17] Cephalus helped Amphitryon of Mycenae in a war against the Taphians and Teleboans.
