Óláfr's time in the Isles is confirmed by several Icelandic sources—the sagas of Hrafn Sveinbjarnarson (an Icelandic chieftain) and Guðmundr Arason (an Icelandic ecclesiast)—which recount how, in 1202, Guðmundr attempted to sail from Iceland to Norway to become consecrated as the Bishop of Hólar. For example, the thirteenth-century "Hrafns saga Sveinbjarnarsonar" relates that the wayfaring Icelanders encountered a severe storm and were blown far off course before being forced to make landfall in the Hebrides. The saga identifies the island they landed upon as "", which may well refer to Sanday, a tiny tidal island linked to its larger neighbour Canna, the westernmost island of the Small Isles. The sandy flat that joins the islands together forms one of the best natural harbours in the Hebrides.
