There are many reliefs of minor supernatural beings, called by such terms as "winged genie", but the major Assyrian deities are only represented by symbols. The "genies" often perform a gesture of purification, fertilization or blessing with a bucket and cone; the meaning of this remains unclear.[18] Especially on larger figures, details and patterns on areas such as costumes, hair and beards, tree trunks and leaves, and the like are very meticulously carved. More important figures are often shown larger than others, and in landscapes more distant elements are shown higher up, but not smaller than, those in the foreground, though some scenes have been interpreted as using scale to indicate distance.
