According to the "Chronicle of Mann", Rǫgnvaldr gave Óláfr possession of a certain island called ""Lodhus"". The chronicle disparagingly describes the island as being mountainous and rocky, completely unsuitable for cultivation, and declares that its small population lived mostly by hunting and fishing. In fact, Lewis is the northern part of the Outer Hebridean island of Lewis and Harris. Whilst the southern part—Harris—is somewhat mountainous, the northern part—Lewis—is rather flat and boggy. The chronicle, therefore, seems to have conflated the northern and southern parts of the island. In any case, the chronicle claims that, because of the impoverishment of his lands, Óláfr was unable to support himself and his followers, and that in consequence he led "a sorry life". The chronicle's otherwise perceptible prejudice against Rǫgnvaldr's branch of the Crovan dynasty, and its apparent bias in favour of Mann over the northernmost reaches of the realm, may also account for its denigrating depiction of Óláfr's allotted lands.
