sentences:  Eric's soubriquet "blóðøx", ‘Bloodaxe’ or 'Bloody-axe', is of uncertain origin and context.It is arguable whether its preservation in two "lausavísur" by Egill Skallagrímsson and a contemporary skald genuinely dates to the 10th century or had been inserted at some stage when Eric was becoming the focus of legend.There is no guarantee that it significantly predates the 12th-century narrative tradition, where it is first attached to him in "Ágrip" and in Latin translation as "sanguinea securis" in the "Historia Norwegiæ."
