What keeps drawing my eye is the chair or throne or whatever it is that looks like it’s scaled with the three heads of whatever creature that is turned and looking at its back with the guy reaching out to the other guy that looks like he has mits or gloves of some sort on his hands.

I’m wondering what that is supposed to be.

I doubt there's any way of telling what the various scenes represent, not without knowing the myths or legends of the culture.

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. No written language is preserved from Hasanlu and archaeologists have yet to identify the ethnic background of the site’s inhabitants. Various interpretations of the mythological scenes place their origins in Urartian, Hurrian, and/or Indo-European traditions
