hringlegnum ‘ring-coiled’: Emended here to m. dat. sg., agreeing with lax ‘salmon’ in l. 7, the latter understood as dat. of the possessor of a body part (hjarta ‘heart’). This description does not necessarily refer to the fact that, in the saga prose (Ragn 1906-8, 117), the snake is described as encircling Þóra’s bower; in Hávm 86/4 (NK 30), the phrase ormi hringlegnom ‘coiled snake’, also in the dat. sg., clearly refers to a snake in general terms.
