Aeetes’ price for the fleece is the motif entire: he promised it “if single-handed he would yoke the brazen-footed bulls” [The Library (Bibliotheca), BOOK I, ch. IX]. The animals are catalogued like armament — “of enormous size, a gift of Hephaestus”; “they had brazen feet and puffed fire from their mouths” [ibid.]. Made by the smith-god, they are met with chemistry: Medea’s drug, with which anointed “he could for a single day be harmed neither by fire nor by iron” — the two hazards the bulls embody, named in order [ibid.]. So “though they charged him with a flame of fire, he yoked them”, and Jason ploughed and sowed the dragon’s teeth [ibid.]. Frazer’s note on the passage sends the reader to Pindar and Apollonius for the same beasts [ibid., editor’s note]; Thompson’s single row is that note. The fire-breathing bull here is a task-monster, not a terror at large — it exists to make one field impossible to plough, and its defeat is not slaughter but harness. The served chapter holds every element — maker, metal, fire, drug, yoke — on one continuous page, which is more than most addresses on this shelf can claim.
