As classy French painters go, James Tissot was a solid second stringer. A good eye for detail and a sure hand at technique, he supported himself painting charming pictures of French scenes for the bourgeois. Had the obligatory scandalous artist life. Turned to religion in his later years.
Like I said, nothing too special about him...until he started painting pictures of Jesus. I'll leave it up to you to decide what happened, but the ol' boy went bonkers and began whipping out a series of water colors that -- while historically accurate and in the artistic style of the day -- would freak out the average Sunday school teacher.
