Thompson's pointer reads "Snorra Edda Gylf. XV." (his apparatus row's words), and on our shelf that chapter is the death of Balder — where the gods' horses do the mourning-work. When Frigg asks who will ride to Hel for Balder, "Odin’s steed, Sleipner, was led forth", and Hermod mounts [The Prose Edda (The Younger Edda), THE FOOLING OF GYLFE. XV]. At Hel's wall "the horse leaped over the gate with so much force that he never touched it" [ibid.]. At the pyre "Heimdal rode his steed Gulltop", and "Balder’s horse, fully caparisoned, was led to his master’s pile" — the mount burns with the master [ibid.]. Even the anti-horse attends: the giantess Hyrrokken "came riding on a wolf, and had twisted serpents for reins" [ibid.]. The candidate lane adds Sleipner's origin two sections earlier: when "a mare suddenly ran out of the woods" to decoy the giant builder's stallion, the mare was Loke, who afterwards bore the gray, eight-footed foal, "the best horse among gods and men" [The Prose Edda (The Younger Edda), THE FOOLING OF GYLFE. XIII]. Three further candidates — two Mahābhārata sections and an Arabian Nights chapter — dissolved on reading: no horses of gods there, only a magician's flying horse with no god astride it.
