Thompson’s pointer (Frazer Apollodorus II 82 n. 2) resolves to a page where the story is famously absent: Apollodorus names Phaethon in a genealogy and walks on, and it is Frazer who supplies the myth — “Apollodorus passes over in silence the famous story” of the chariot, the thunderbolt, the fall into Eridanus, “his sisters mourned for him till they were turned into poplar trees”, “their tears being changed into drops of amber which exuded from the trees” [The Library (Bibliotheca), BOOK III, ch. XIV, editor’s note]. The note aims at Ovid, and Ovid is served. Sister by sister the transformation takes them — Lampetie “was detained by a root suddenly formed”, “bark closes upon their loins”, and their mother, tearing at the branches, finds “drops of blood flow as from a wound”; “The bark came over the last words” [The Metamorphoses of Ovid, Book 2]. Then the aetiology proper: “amber distilling from the new-formed branches, hardens in the sun”, and the clear river sends it “to be worn by the Latian matrons” — grief become jewelry, trade route included [ibid.]. An editor’s note that only pointed turned out, on reading, to point at a served primary text; the wiring should follow.
