I went to the Musee des Beaux Arts in Arras last week and saw some 16th C French/Flemish religious paintings onloan from the Louvre.
Although they were wonderful (technically) they did not move me like the Italian Old Masters of the 15th C.
Nor were they as impressive as the Dutch Old Masters of the 17th C.
I'm thinking that the most important French movement was the Impressionists of the late 19th C.
