Imagine if you lived in the day. All art was photo like. Then this guy comes along who sees technique, light and color in a different way. No wonder he was thought to be nuts!
A great book to read to understand Van Gogh is “Lust for Life” by Irving Stone.
Most folks don’t know that Vincent Van Gogh was, at one time, a missionary to the coal miners in Belgium.
He was a deeply sensitive and spiritual man.
