"Singing stone", "Chanting stone." A verse from the tenth-century skaldic poem Húsdrápa by Úlfr Uggason, and quoted by Snorri Sturluson, mentions Singasteinn as the place where Heimdallr contended with Loki over a precious stone (sea-kidney):
- The famed rain-bow's defender,
- Ready in wisdom, striveth
- At Singasteinn with Loki,
- Fárbauti's sin-sly offspring;
- The son of mothers eight and one,
- Mighty in wrath, possesses
- The Stone ere Loki cometh;
- I make known songs of praise.
Snorri makes this stone or object they fought over the Brísinga-men, the famed necklace of Freyja, and adds that they were in seal form.
