The winged genie is shown holding a conical fruit which has presumably been dipped into a bucket of pollen held in preparation for fertilizing the Tree of Life, an important symbol in Assyrian religious belief.
I took these photos at the Los Angeles County Museum of Art. The reliefs are from interior walls of the palace of Ashurnasirpal II who reigned from 883 to 859 BC. He was the first Assyrian king to use carved reliefs on the interior walls of a palace at the site of Kalhu (now called Nimrud).
