Hengist is briefly mentioned in Prologue, the first book of the Prose Edda, written by Snorri Sturluson in the 13th century. In Prologue, a euhemerized account of the origins of Norse mythology is provided, including that while Odin was in Saxony, Odin put three of his sons in charge of the area. One of these three sons was Veggdegg, a "powerful king" who ruled over eastern Saxony. One of Veggdegg's sons was Vitrgils, the father of Vitta, father of Hengist. Vitta's other son (and Hengist's uncle) was Sigar, father of Svipdagr.
