Note 173 — BOOK III
Evelyn S. (Evelyn Shirley) Shuckburgh translation
This division of the world into three parts was an advance upon the ancient geographers, who divided it into two, combining Egypt with Asia, and Africa with Europe. See Sall. Jug. 17; Lucan, Phars. 9, 411; Varro de L. L. 5, § 31. And note on 12, 25.
