To the information conveyed by Sigefrid's Vita I, that he died and was buried in Växjö, the late-medieval author of Óláfs saga Tryggvasonar en mesta adds an anecdote about Bishop 'Sigurd', set in 'a town called Värend'. This story alleges that the bishop had become slightly forgetful about the niceties of Church discipline before his death in extreme old age. But, while it is doubtless the case that fuller accounts of the life of St Sigfrid were in circulation in the pre-Reformation era than now, a warning has already been given against trusting the reportage of this particular Icelandic author.
