He has good reason to love those high mountains, which rise many thousands of feet above the plain, for even in the hottest weather, when the heat in Shushan would otherwise be unbearable, he can always enjoy the cooling breezes which come from the everlasting snow-fields on the top of that mountain range, and which blow refreshingly over the sultry plain beneath.
The City of Lilies is a very ancient place.

It was probably built long before the time of Abraham.

We read in Gen.xiv.of a certain Chedorlaomer, King of Elam, who gathered together a number of neighbouring kings, and by means of their assistance invaded Palestine, and took Lot prisoner.

This Chedorlaomer probably lived by these very rivers, the Choaspes and the Ulai, and Shushan was the capital city of the old kingdom of Elam over which he ruled.
Later on the City of Lilies was taken by the Babylonians.

They had their own capital city, the mighty Babylon, on the Euphrates.
