Unknown, Poetic Edda — Reginsmál (1907)
“ Sigurd went to Hialprek's stud and chose himself a horse, which was afterwards named Grani. Regin, Hreidmar's son, was then come to Hialprek; he was the most skilful of men, and a dwarf in stature; he was wise, cruel, and versed in magic. Regin undertook the rearing and instruction of Sigurd, and bore him great affection. He informed Sigurd of his parentage, and how it befell that Odin, and Honir, and Loki came to Andvarafors. In the fall there was an abundance of fish. ”
