The earliest text which has been claimed to be a description of the Faroe Islands was written by an Irish monk in the Frankish Kingdom named Dicuil, who, around 825, described certain islands in the north in "Liber de Mensura Orbis Terrae", (Measure/description of the sphere of the earth). Dicuil had met a "man worthy of trust" who related to his master, the abbot Sweeney (Suibhne), how he had landed on the Faroe Islands after having navigated "two days and a summer night in a little vessel of two banks of oars" ("in duobus aestivis diebus, et una intercedente nocte, navigans in duorum navicula transtrorum").
