Sigvat Thordarson (ca. 995 – ca. 1045) An Icelandic skald, Sigvat served as a court poet to Olaf II Haraldsson of Norway, Magnus I the Good of Norway, and Canute I the Great of Denmark, and served as Olaf’s marshal. With approximately 160 extant verses, more of his work survives than that of any other skald from his era. As a Christian, he is notable for avoiding, for the most part, the allusions to pagan mythology characteristic of earlier skaldic verses. Sigvat is also a significant contributor to the Heimskringla, particularly Olaf’s saga Haraldsson.
