Water Lilies 11 by Claude Monet is one I hadn't previously come across. Instead of is usual greens and blues, Monet paints this using bold oranges. It looks as though the water is on fire--definitely a departure from the calming water lily paintings many of us have come to expect.
The reflection of the sun on the water makes it look as though it is not water at all, but an exploding volcano--quite a juxtaposition of images.
"Slavery ended in medieval Europe only because the church extended its sacraments to all slaves and then managed to impose a ban on the enslavement of Christians (and of Jews). Within the context of medieval Europe, that prohibition was effectively a rule of universal abolition. "— Rodney Stark
