Hi Everyone,
I spent time in Arles last summer and visited the spot of VanGogh's 'Cafe Terrace at Night' while on the RS Loire/South of France tour. I just read an interesting article about possible religious symbolism in the painting that had previously gone unnoticed. You might be interested.
For some reason, I can't get the hyperlink to work, but if you google: Van Gogh may have hidden 'The Last Supper' within one of his most famous paintings
you'll find it on it on Huffington Post. :) Enjoy!
