járnviðju ‘the female from Járnviðr’: This is to be identified as Skaði, as the poem presently explains (cf. Hkr 1893-1901, IV). Vsp 40/2 represents Járnviðr as a forest in the east where a troll-woman gives birth to giants in the form of wolves (cf. Gylf, SnE 2005, 14; Simek 1993, 179). The p. n. means ‘Iron-wood’.
