At all events, the frequent association of Shamash and Ramman cannot have been accidental.

This double nature of Ramman--as a solar deity representing some particular phase of the sun that escapes us and as a storm-god--still peers through the inscription above noted from the Cassite period where Ramman is called 'the lord of justice,'-- an attribute peculiar to the sun-god; but in Assyria his role as the thunder-and storm-god overshadows any other attributes that he may have had.
There are two aspects to rainstorms in Babylonia.

The flooding of the fields while committing much havoc is essential to the fertility of the soil.

Ramman is therefore the carrier of blessings to the cities, the one who supplies wells and fields with water; but the destructive character of the rain and thunder and lightning are much more strongly emphasized than their beneficent aspects.

Even though the fields be flooded, Ramman can cause thorns to grow instead of herbs.
