Thompson's row holds two pointers, and both resolve on our shelf — one thin, one thick. The wired page is a genealogical crumb with a promissory note: Melpomene "had by Achelous the Sirens, of whom we shall speak in treating of Ulysses" [The Library (Bibliotheca), BOOK I, ch. III]. The promise is kept in the served Epitome, where the row's second pointer lands: "the Sirens were Pisinoé, Aglaope, and Thelxiepia" — lyre, voice, and flute — who by music "persuade passing mariners to linger" [The Library (Bibliotheca), APOLLODORI BIBLIOTHECA, ch. 33]. There the body-plan arrives, and it contradicts the label. Thompson writes "Bird with woman's head"; the served text builds the creature the other way up: "from the thighs they had the forms of birds" — woman above, bird below [ibid.]. Frazer's note assembles the ancients on the text's side: Aelian's poets and painters made them "winged maidens with the feet of birds", and Hyginus "describes the Sirens as women above and fowls below" [ibid., editor's note]. The reader should know the head-allocation is Thompson's, not any served line's. Wax, mast, and the bound listener stand in the same Epitome paragraph: the anatomy and the deception share one page.
