(3) We find that the region about Babylon itself was called Kar-dunishi—­which easily recalls Kar or Gan-Eden.  We also find the name (Tintira) applied, indicating a “grove” or “fountain” of life; in the locality where the direct legends most abound.

(4) We find from ancient authors that the district was one of rich verdure—­a land of gardens and irrigation.

(5) We find that some way above Babylon about Accad, the level of the river bed Euphrates is so much higher than the valley of the Tigris eastward, that numerous streams flow off from it, which would serve admirably to irrigate a garden situated between the two, eastward of the Euphrates.

(6) We find that the Persian Gulf once extended more than one hundred miles farther inland than it does now.  That there was no joint outflow of Tigris and Euphrates, but, though they did join their streams above, they parted again and had still separate mouths—­of the Tigris branch one, of the Euphrates several.

(7) Lastly, Professor Delitzsch finds two channels which answer to Pison and Gihon.

(8) He proves these two to be the right ones by considering the countries which they “compass:”  and actually finds the one that he supposes to be the “Gaihun,” called, in the cuneiform clay tablets, “Kahan or Gaghan-de.”

It is really only in (7) and (8) that there is any room for doubt and for further inquiry.

At any rate, the credibility of the narrative, and a belief in its purpose, as a topographically exact statement of fact, not an allegory or legend, is established.
