I don’t see floating head, just long neck/etc. I have no clue what the scene is depicting, maybe searches on Mar A Lago will describe? Another point is that in 16/17th century art (and earlier as well) often portrayed biblical scenes and stories with the personalities attired in contemporary clothing.
My mother was an art historian and I grew up as child looking at the pictures in the art books that lined the walls and reading about them, so this is something I am familiar with. Not ascertaining the nature of this portrayal, I have no idea what’s going on. But the lack of 2000 year old middele eastern dress style does not necessarily mean anything one way or the other.
Thank you for this update. I wondered if using more contemporary styles could be the artist's concept in the scene. I have no art history knowledge at all.
Way behind now. Got to catch up.
