The Nuttall Encyclopedia

A son of Tithonus and Aurora, who was sent by his father, king of Egypt and Ethiopia, to the assistance of Troy on the death of Hector, and who slew Antilochus, the son of Nestor, and was himself slain by Achilles, whereupon Aurora, all tears, besought Zeus to immortalise his memory, which, however, did not calm her sorrow, for ever since the earth bears witness to her weeping in the dews of the morning; a statue, presumed to be to his memory, was erected near Thebes, in Egypt, which was fabled to emit a musical sound every time the first ray fell on it from the rosy fingers of Aurora.
