The bowl’s repoussé and chased decoration depicts several complex figural scenes, mostly mythological. The origin and precise meaning of the pictorial scenes have been the subject of scholarly debate.

Various interpretations of the mythological scenes place their origins in Urartian, Hurrian, and/or Indo-European traditions
