He marched over the country doing this until he had crossed over from Asia (continent)Asia to Europe (continent)Europe and defeated the Scythians and Thracians. Thus far and no farther, I think, the Egyptian army went; for the pillars can be seen standing in their country, but in none beyond it.
From there, he turned around and went back home; and when he came to the Phasis river, that King, Sesostris, may have detached some part of his army and left it there to live in the country (for I cannot speak with exact knowledge), or it may be that some of his soldiers grew weary of his wanderings, and stayed by the +Poti [41.683,42.183] (inhabited place), regions under republican jurisdiction, Georgia, Asia Phasis.
For it is plain to see that the Colchians are Egyptians; and what I say, I myself noted before I heard it from others. When it occurred to me, I inquired of both peoples; and the Colchians remembered the Egyptians better than the Egyptians remembered the Colchians;
the Egyptians said that they considered the Colchians part of Sesostris' army. I myself guessed it, partly because they are dark-skinned and woolly-haired; though that indeed counts for nothing, since other peoples are, too; but my better proof was that the Colchians and Egyptians and Ethiopians are the only nations that have from the first practised circumcision.
The Phoenicians and the Syrians of +Palestine [35.333,31.916] (region (general)), Asia Palestine acknowledge that they learned the custom from the Egyptians, and the Syrians of the valleys of the Thermodon and the Parthenius, as well as their neighbors the Macrones, say that they learned it lately from the Colchians. These are the only nations that circumcise, and it is seen that they do just as the Egyptians.
