They wetre a group of superb painters from England, who started a brotherhood against the Academy. They created their own special way of painting, so the pictures have a type of inner-lit, mystical look. They did it by the way they primed their canvasses, using a wet yellow ground. I used to know the technique, can't remember but it's very labor intensive.
They painted allegorical, poetc themes out of Shakespeare, Keats and Tennyson and mythology.
If I recall, 'The Light of the World' was like Star Wars of the day (mid 1800's) People lined up for block s and blocks to see it.
They painted everything from life in meticulous detail, making really very beautiful but maybe overy sensuous paintings. They married their models, having a romantic ideal of elevating a common woman to a higher level ..I don't explain this well.
So, 'The Light of the World' is so famous and often reproduced, I have no idea if the original includes occultic trash.
I really hope not, but then again, it would not surprise me. But also someone could have tampered with the reproductions.
