[4] Hilditanns ‘of Hilditann (“War-tooth”)’: The reference is to Haraldr hilditǫnn Hrœreksson, a Danish king of legendary times (see Note to SnSt Lv 5/1, 4). His family is thus the line of Danish kings. The form is unusual, as the epithet is usually f. hilditǫnn. Masculine -tanns has certain parallels (e.g. Sigurðr sýr ‘Sow’ (f.) could be sýrr (m.) as well); and -tanns rather than ‑tannar is required by the metre.
