In Greek mythology, Cedalion or Kedalion ( Classical Greek Κηδαλίων) was a servant of Hephaestus in Lemnos. According to one tradition, he was Hephaestus's tutor, with whom Hera fostered her son on Naxos to teach him smithcraft. Kerenyi compares him to the Cabeiri, to Chiron, and to Prometheus.
The more common story of Cedalion tells of his part in the healing of Orion, who came to Lemnos after he was blinded by Oenopion. Orion took up Cedalion and set the youth upon his shoulders for a guide to the East. There the rays of Helios restored Orion's sight.
Sophocles wrote a satyr play Cedalion, of which a few words survive. Its plot is uncertain, whether the blinding of Orion by Oenopion and the satyrs on Chios, probably with Cedalion offstage and prophesied, or the recovery of Orion's sight on Lemnos. It has also been suggested that the subject may be Hephaestus's fostering; or the instructions given to the blinded Orion by satyrs in Cedalion's service. One of the surviving lines suggests extreme drunkenness; Burkert reads this fragment as from a chorus of Cabeiri.
One traditional etymology is from kēdeuein "to take charge, to care for", and early nineteenth century scholars agreed. Scholars since Wilamowitz, however, support the other traditional interpretation, as "phallos", from a different sense of the same verb: "to marry" (said of the groom).
Wilamowitz speculates that Cedalion is the dwarf in the Louvre relief showing Dionysius in Hephaestus' workplace.
