Note 29 — The Ballad of Grimnir

This stanza looks as though it originally had had nothing to do with the two preceding it. Snorri quotes it in his description of the three roots of Yggdrasil, and the three springs beneath them. “The third root of the ash stands in heaven and beneath this root is a spring which is very holy, and is called Urth’s well.” (Cf. Voluspo, 19) “There the gods have their judgment-seat, and thither they ride each day over Bifrost, which is also called the Gods’ Bridge.” Thor has to go on foot in the last days of the destruction, when the bridge is burning. Another interpretation, however, is that when Thor leaves the heavens (i.e., when a thunder-storm is over) the rainbow-bridge becomes hot in the sun. Nothing more is known of the rivers named in this stanza. Lines 3–4 are almost certainly interpolated from stanza 30.
