In the latter decades of the ninth century during the Late Anglo-Saxon period, Scandinavian settlers arrived in Britain, bringing with them their own, kindred pre-Christian beliefs. No cultic sites used by Scandinavian pagans have been archaeologically identified, although place names suggest some possible examples. For instance, Roseberry Topping in North Yorkshire was known as Othensberg in the twelfth century, a name which derived from the Old Norse Óðinsberg, or 'Hill of Óðin'. A number of place-names also contain Old Norse references to mythological entities, such as alfr, skratii, and troll. A number of pendants representing Mjolnir, the hammer of the god Thor, have also been found in England, reflecting the probability that he was worshipped among the Anglo-Scandinavian population. Jesch argued that, given that there was only evidence for the worship of Odin and Thor in Anglo-Scandinavian England, these might have been the only deities to have been actively venerated by the Scandinavian settlers, even if they were aware of the mythological stories surrounding other Norse gods and goddesses. North however argued that one passage in the Old English rune poem, written in the eighth or ninth century, may reflect knowledge of the Scandinavian god Týr.
