As to the fourth river (Gihon), Delitzsch identifies it, still more clearly, with a channel known as the "Shatt-en-níl," which branches off from the Euphrates at Babylon itself, and passing the Scriptural city of Erech, rejoins the main river lower down. A clay tablet has actually been discovered, having the Euphrates, Tigris, and this Shatt-en-níl channel _together_: the name of the latter is given as "K[=a]hán de," or "Gughánde," a name which closely resembles Gihon. The channel is, however, identified independently of the name. For the Gihon is particularized in the narrative, by the fact that it "compasses" the land of Cush. This (as already pointed out) is not the Ethiopian Cush. Delitzsch states, that the whole country bounded by this branch was anciently called Kash-shu, which he identifies with the Cush of Genesis ii. The syllable "Kash" appears throughout this locality. In fact Kash-du or Kal-du is the origin of the familiar name Chaldea. In the Hebrew, Kush (Cush) is the name given to the father of Nimrod, who "began" his kingdom about this very site--Erech, and Calneh, and Accad (Gen. x. 8, 10). Hence it is not surprising that relics of the name should be found all round this neighbourhood. Nor does the evidence end here. The district immediately around Babylon was called "Kár-dunish-i," i.e., the "Garden of the god Dunish." Now Kar is the Turanian form of the Semitic G[=a]n, or Gin[=a] (garden); and what is more likely than that, as the true story was lost in the heathen traditions and mythology that grew up, the "garden" was attributed to the god Dunish--whereas the real original had been not "Gàndunish," but "Gan'Eden?" This, though only a conjecture, is the more probable, as one of the inscription-names of Babylon itself was "Tintira," which, though a little obscure, certainly means _either_ the "_grove_," or the _"fountain," of life._
