Bede,
"The Lesser Chronicle"(chapters 16–22 of On Times…
“ By six ages of the world are the times distinguished: 3. The first age from Adam to Noah, containing 10 generations. Truly, 1656 years. Then all was lost to flood, just as oblivion is wont to drown infancy. 4. The second from Noah to Abraham, similarly embraced 10 generations, but 292 years. Then language—that is, Hebrew—was invented. For just so a man begins to know to speak from boyhood after infancy, which likewise takes its name from fari, [1] i.e. because he cannot speak. ”
