Isidore of Seville in his "Etymologiae" (c. 600) mentions the number of 72; however, his list of names from the Bible drops the sons of Joktan and substitutes the sons of Abraham and Lot, resulting in only about 56 names total; he then appends a list of some of the nations known in his own day, such as the Longobards and the Franks. This listing was to prove quite influential on later accounts that made the Lombards and Franks themselves into descendants of eponymous grandsons of Japheth, e.g. the "Historia Brittonum" (c. 833), "The Meadows of Gold" by al Masudi (c. 947) and "Book of Roads and Kingdoms" by al-Bakri (1068), the 11th-century "Lebor Gabála Érenn", and the midrashic compilations "Yosippon" (c. 950), "Chronicles of Jerahmeel", and "Sefer haYashar".
