Up to a late period Aramaic hordes appear from time to time in western Assyria; and in a higher stage of culture, contact between Aramaeans and Assyrians was maintained by commercial intercourse and by warfare.

Since the earliest mention of Ramman's cult is in the city of Ashur, it may be that he was originally connected with that place.

As already intimated, he was essentially a storm-god, whose manifestation was seen in the thunder and lightning, and the god was known not merely as 'the thunderer,' but also as Barku, _i.e._, lightning.

Perhaps it was because of this that he was also brought into association with the great light of heaven,--the sun-god.

In many mythologies, the sun and lightning are regarded as correlated forces.
