The two chief seats of his worship were Ur in the S., and Harran considerably to the N., but the cult at an early period spread to other centres, and temples to the moon-god are found in all the large cities of Babylonia and Assyria.
The name of Sin's chief sanctuary at Ur was E-gish-shir-gal, "house of the great light"; that at Harran was known as E-khul-khul, "house of joys."
Here the Belikh (Bilechas) joins the Euphrates, flowing southward through the biblical Aram Naharaim from Urfa (Edessa) and Harran (Carrhae); and from this point to el-IKaim four days' below Deir, the course of the river is south-easterly.
Abraham, it was believed, came from Harran (Carrhae), primarily from Babylonia, and Jacob re-enters from Gilead in the north-east with his Aramaean wives and concubines and their families (Benjamin excepted).
Again, in 1104, the Normans, while attempting to capture Harran, were badly defeated on the river Balikh, near Rakka; and this defeat may be said to have been fatal to the chance of a great Norman principality.'
