About those paintings:

There have been people educated in this art and its history, etc., who say that those "UFOs" depicted in paintings are merely "symbols" to symbolize divinity or something like that (but I forgot where it was). They say it has nothing to do with UFOs the way we think about them.

But then again.... it doesn't take a genius to figure out the shape of those things. Symbols or not: they certainly look like 'em.

(Btw, this link's got some nice stuff: http://www.dudeman.net/siriusly/ufo/art.shtml)

Makes me think... If they are used in these paintings to portray divinity, is it so that aliens are our "Gods"? :P

Vessels of angels, the Church, this and that, I just dunno.
