The "Prose Edda" relates that when Thor cooks the goats, their flesh provides sustenance for the god, and, after Thor resurrects them with his hammer, Mjölnir, they are brought back to life the next day. According to the same source, Thor once stayed a night at the home of peasant farmers and shared with them his goat meal, yet one of their children, Þjálfi, broke one of the bones to suck out the marrow, resulting in the lameness of one of the goats upon resurrection. As a result, Thor maintains Þjálfi and his sister Röskva as his servants. Scholars have linked the ever-replenishing goats to the nightly-consumed beast Sæhrímnir in Norse mythology and Scandinavian folk beliefs involving herring bones and witchcraft.
