The one thing I'd like to say about Belgium: What is better than chocolates, Bosch, and Van Eyck in fairy-tale medieval wonderlands?
Right: Sketches from the Ghent Altarpiece finished by Jan Van Eyck (his brother began it). The reason I originally went to Belgium was to see this altarpiece.
I fell in love with Jean Carries' work in the Petit Palais (little palace built for the World Expo, now a free museum). Seriously amazing creature ceramics.
The three following sketches were done in Giverny in the gardens around Monet's house. It may be the most beautiful place in the world; the flowers were amazing even in October. When I was little I read the children's book Linnea in Monet's Garden and ended up recreating her trip without even intending it (Orangie Museum one day to see the water lily rooms, Giverny the next).
Paris, the Louvre.
Medieval wing of the Louvre.
From the Cluny Museum of the Medieval Age. I love crazy medieval headwear.
Sketches from various pieces in the Centre Pompidou.
