, is recorded as being in Sveinn's service and very little of his poetry has come down to us. The written sources mentioning Sveinn were all written over 150 years after his death. The Swedish historian Staffan Hellberg in 1972 claimed to be able to show that Sveinn was a fictitious person, and that he had never lived.Hellberg, Staffan (1972). ''Slaget vid Nesjar och "Sven jarl Håkonsson"''. Scripta Islandica, Uppsala 1972, pp. 21–30 (in Swedish). The debate about this formed part of the wider debate about the value of the 12th and 13th century sagas for 11th century history and earlier, and is an example of the saga skepticism, particularly widespread in Swedish academia. Hellberg's conclusions remain speculative.
