Peter Breghul was a pupil of Bosch and his painting the triumph of death (once wrongly attributed to Bosch)was reproduced on the cover of Black Sabbaths greatest hits, I would look at the cover for hours when I was stoned. Many of Breghuls paintings have a halluncinationary aspect. I never heard the the ergotism theory before in relation to Bosch and I intend to look into it as I am intrigued,
This one always gives me the creeps. But I love it so....
It's funny, Grant Wood was only given a bronze award and $300 for this masterpiece back in the day.
