If my understanding is correct, there are different hierarchies of both angels and demons.

Angels are depicted in strange ways because of having many wings at a time but also having many halos of fire but no human body.

Demons are portrayed in a variety of different ways and there were different depictions and hierarchies of demons like the Seven Princes of Hell.

But Biblical texts do not describe these beings the way we know today so where did these portrayals come from and why did they stick?
