Liber Historiae Francorum
The Frankish mythology that has survived in primary sources is comparable to that of the Aeneas myth of in Roman mythology, but altered to suit Germanic tastes. Like many Germanic peoples, the Franks told a founding myth to explain their connection with peoples of classical history. In the case of the Franks, these people were the Sicambri and the Trojans. An anonymous work of 727 called "Liber Historiae Francorum" states that following the fall of Troy, 12,000 Trojans led by their kings Priam and Antenor moved through the Sea of Azov and up the Tanais (Don) river and settled in Pannonia, where they founded a city called "Sicambria". After altercations the Alans and Emperor Valentinian (late 4th century AD), who renamed them Franks, they moved to the Rhine.
