The Prologue is the first section of four books of the Prose Edda, and consists of a euhemerized account of the origins of Norse mythology: the Norse gods are described descended from the Trojans.
The genealogy presented by Snorri begins with Priam. Priam's daughter Tróán married king Múnón or Mennón. Their son was Trór, or Thor, who was fostered in Thrace. Thor slew his foster father and married Sibil, identified with Sif. The line of descendants of Thor and Sif is given as follows:
Finally, the son of Fríallaf was "Vóden, whom we call Odin", who came to Germany (Saxland) and established the royal lines there.
In Saxland, Odin's sons Vegdeg, Beldeg (Baldr) and Sigi founded the ruling houses of the Franks, from whom descended the Völsungs. Odin himself moved on to Jutland (Reidgothland), where he established his son Skjöldr, from whom derive the Skjöldungs, the kings of the Danes. After this, Odin went on to Sweden, where there was a king named Gylfi. Gylfi welcomed Odin and his train as "men of Asia, who were called Æsir". In Sweden, Odin founded a city called Sigtún as a Trojan colony. Later, Odin's son Yngvi became king of Sweden, founding the Yngling dynasty. Finally, Odin went on to Norway, where he established his son Sæmingr as king.
The Prologue concludes in a linguistic remark, observing that the Æsir when they came to the north, spread out until their language was the native language over all these lands.
