[1, 4] Hringi ok Hilditanni ‘Hringr (“Ring”) and Hilditǫnn (“War-tooth”)’: The Danish legendary king Haraldr hilditǫnn Hrœreksson and his son-in-law, the Swedish king Sigurðr hringr Randvésson, known from Saxo (Saxo 2005, I, 8, 1, 1-5, 1, pp. 510-23) and Skjǫldunga saga (ÍF 35, 58-69). See also Notes to RvHbreiðm Hl 39 [All] and 41 [All]. The battle instigated by Óðinn and used as a frame of reference by Snorri here is the epic battle of Brávellir at which Haraldr hilditǫnn fell. According to legend, Óðinn participated in that battle disguised as Brúni, a counsellor of Haraldr’s, but he turned against Haraldr and ultimately killed him.
