Time for a few Bosch headers for the blog. One of the great Flemish “primitives”. What was his art all about? Was it the product of some strange wheat blight? Excess of religious zeal? An unhinged mind? Is there a hidden message in there about alchemy (as suggested by Laurinda Dixon in her excellent book Bosch published by Phaidon)? Or is it a visual treatise on Hell, Heaven, and the Garden of Eden?
