The Oaths

In the Eddas, Baldr dreams of his own death, and the gods take the dream seriously. Frigg takes an oath from everything that might harm him — fire and water, iron and every metal, stones, earth, trees, sicknesses, beasts, birds, poison, serpents. All of them swear. So the gods invent a game out of it: they stand Baldr up in the assembly and throw things at him, shoot at him, strike at him, and nothing touches him. Snorri's phrasing is that this seemed a great honour to them all. It is one of the few genuinely happy scenes in Norse myth, and it is a scene about a loophole nobody has found yet.
