Apollodorus gives the diver one dry clause: Aesacus, Priam's first son, mourning his dead wife, "was turned into a bird" [The Library (Bibliotheca), BOOK III, ch. XII]. The species is the editor's: the bird "appears to have been a species of diver", with a pointer to Ovid [ibid., editor's note]. Follow the pointer and the shelf supplies the whole etiology, for the Metamorphoses is served too: guilty of the chase that killed the nymph — "The wound was given by the serpent; by me was the occasion given" — Aesacus "hurled himself into the sea" [The Metamorphoses of Ovid, Book 11]. Tethys, pitying, "covered him with feathers as he swam through the sea", refusing him the death he sought; so he dives forever — "again he throws his body in the waves: his feathers break the fall", and "incessantly tries the way of destruction" [ibid.]. Even the anatomy is grief — "Love caused his leanness", the long neck, the far-off head — and the translator's synopsis names the result: he "is transformed into a didapper" [ibid., translator's note]. The diver is a suicide the sea keeps catching; its endless plunging, says our one resolved Thompson row, is where the bird came from.
