Most of Olvir Hnufa's life is covered in three sagas, Egil's saga, Skaldatal and Prose Edda. Egils saga spans the years 850-1000 and covers the saga of the ancestors of Egill Skallagrímsson, including Olvir Hnufa. Skaldatal are poetries from Prose Edda about court poets. Prose Edda is an saga from the 13th century about the norse mythology, which is used to explain poetry from that era.
