moluðu mold til matar ‘they were crushing earth into food’: Cf. Grott where the giantesses Fenja and Menja are condemned to grind out gold from a magic mill. Njörður Njarðvík (1991, 88-9) notes that earth does not need grinding (though it may need crushing!), and that this is therefore an unending task. A similar punishment appears in the ‘Vision of the Monk of Wenlock’ (Tangl 1916, 13).
