I love that art!! This makes me remember a passage we translated for Ancient Greek class about vultures carrying the souls of the dead to the moon. Unfortunately I don’t remember where that passage was from and internet searches have turned up nothing. Also on the subject of vultures, the stone circles at Gobekli Tepe had a pair of stones in the center of the circles where corpses would be placed on a wooden platform and fed to the vultures. This seems to be just one step in the ritual process corpses would undergo. Anyway there’s a connection between vultures and the moon that is very old, and I would say also an old idea that the moon is where the afterlife is or connected to it or a gateway or part of the journey of souls.
