In 1606 Caravaggio was using prostitutes to represent his Virgin Mary’s and his young lovers to represent cupids. Most of his paintings are about real people living their lives, gambling at the kitchen tables, walking bare feet in the muddy streets, singing, playing, discussing and also fighting. He was using radical cultural associations not just to provoke, but to speak to the audience of his time. In fact if you look at his colleagues you will see Saints all covered in crowns, wearing golden sandals and silky dresses. Roman churches were adorned with the world’s best marbles and its cardinals were wearing the most precious silks. As a roman citizen of the 1600s you would have probably felt astonished in front of all that opulence that was probably paid for with your, and the richest European’s, courts taxes.
