I went to see the Forests, Rocks, Torrents exhibition of Swiss and Norwegian landscape paintings at the NG. My favourite discovery was Knud Baade, represented in the exhibition by a single seascape (the first one below). He was known for his depicitions of a mythical Norway of warrior sagas. His dramatic moonlit seas and mountains seem to have an echo in modern fantasy painting. I like them a lot.
The exhibition's on until the 18th September, and it's free. Go see.
