[4] eylúðrs ‘of the island-mill-box [SEA = Ægir]’: Krause (1969, 88) translates eylúðr as Inselkasten ‘island-bin’ and compares it to sea-kennings such as eygarðr ‘island-enclosure [SEA]’ in Hharð Gamv 6/6^II (see also Meissner 94-5). The meaning of lúðr is uncertain, however. According to Fritzner: lúðr, the word refers to a Stok, som tjener til Underlag for Kværn, hvorpaa den underste Møllesten hviler, Møllebænk ‘a trunk on which the bottom millstone rests, which serves as a platform for a grinding mill, mill-bench’. LP translates lúðr as kværnkasse (af firkantet form, hvori de runde kværnstene ligger, og som står på 4 ben, söjler) ‘mill-box (square in shape, containing the round millstones, resting on four legs, columns)’. If we take lúðr here as pars pro toto for ‘mill’, it yields a sea-kenning of the same pattern as Grotti skerja ‘Grotti <hand-mill> of the skerries’ (Meissner 1927, 4; Tolley 1994-7, 70). Bugge (1886, 336) calls attention to a similar expression, eymylvir ‘island-grinder’, in ÞSjár Frag 4/4. Eylúðr is otherwise attested once as a name for Óðinn (see Þul Óðins 7/1 and Note there).
