There are several mediaeval historiographic accounts that attempt to make an enumeration of the languages scattered at the Tower of Babel. Because a count of all the descendants of Noah listed by name in chapter 10 of Genesis (LXX) provides 15 names for Japheth's descendants, 30 for Ham's, and 27 for Shem's, these figures became established as the 72 languages resulting from the confusion at Babel—although the exact listing of these languages changed over time. (The LXX Bible has two additional names, Elisa and Cainan, not found in the Masoretic text of this chapter, so early rabbinic traditions, such as the "Mishna", speak instead of "70 languages".) Some of the earliest sources for 72 (sometimes 73) languages are the 2nd-century Christian writers Clement of Alexandria ("Stromata" I, 21) and Hippolytus of Rome ("On the Psalms" 9); it is repeated in the Syriac book "Cave of Treasures" (c. 350 CE), Epiphanius of Salamis' "Panarion" (c. 375) and St. Augustine's "The City of God" 16.6 (c. 410). The chronicles attributed to Hippolytus (c. 234) contain one of the first attempts to list each of the 72 peoples who were believed to have spoken these languages.
