Bede : The sons of Ham: Cush, and Mizraim, and Phut and Canaan. Cush is today called Ethiopia by the Hebrews, Mizraim is Egypt, Phut is Libya, from whom even to this day a river in Mauretania is called Phut, and the whole region around it is called Phutensis. Moreover, Canaan possessed the land which the Jews subsequently took over by expelling the Canaanites. — Commentary on Genesis (Hexaemeron) Cosmas Indicopleustes : The river Phison separates all the countries of India [lying along its course] from the country of the Huns. In scripture the Indian region is called Euilat (Havilah). For it is thus written in Genesis: Now the river goeth out from Eden to water Paradise. And from there it was parted and became four heads. The name of the first is Phison (Pishon); that is it which compasseth the whole land of Euilat, where there is gold; and the gold of that land is good; there is the carbuncle and the jasper stone; where the writer clearly calls the country Euilat. This Euilat, moreover, is of the race of Ham. For thus again it is written: The sons of Ham, Cush and Misraim, Phut and Caraan the sons of Cush, Sabâ and Euilat; that is the Homerites and Indians, for Sabâ is situated in the Homerite country, and Euilat is in India. For the Persian Gulf divides those two countries. And that country has gold according to sacred scripture. It has also the pezerôs which Scripture calls anthrax (carbuncle) and the jasper stone, by which it designates the leek-green stone. Clearly therefore does divine scripture, as being really divine, relate these things, even as the whole of our treatise goes to show. — The Christian Topography, Book 11 Jerome : (Verse 6) The sons of Ham: Cush, Egypt, Put, and Canaan. Cush, even to this day, is called Ethiopia by the Hebrews; Egypt is called Mizraim, and Put is called Libya. From Put, the river of Mauritania is called as such, and the entire region surrounding it is known as the Putian region. Many Greek and Latin writers attest to this. However, it is not the place or time to discuss why the ancient name of Libya has remained only in a certain part of the region, and the rest of the land is called Africa. Furthermore, Canaan obtained the land, which the Jews subsequently possessed, after driving out the Canaanites. — Hebrew Questions on Genesis
