In a way. The Pre-Raphaelites and their aesthete descendants show that in a secure civilization - maintained, as always, by military men and women living in the dirt in the pestilential parts of the globe - the comfortable can indulge in fantasy to their hearts' content, protected from from banal reality.
I like the paintings, especially the odalisques (I was a dancer, back in the day), but I like Whistler better.
Their painting style remind me a great deal of Raphael (duh!) and his times in Italy were not particularly secure so I don’t think the style is linked to security.
What I think I mean is that the skill level is linked to civilization at its highest. Just the ability to paint so beautifully is indicative of high civilization. Some might call it overly refined and sort of spiritless, I suppose.
