Masterpiece of the week

The Lower Falls of the Labrofoss, 1827, by Johan Christian Dahl
The dark trees, purple rocks and eerie distant luminosity of a landscape near Oslo give a melancholy dreaminess to this archetypal Romantic painting. Dahl was Norway’s answer to Turner and famous enough in the early 19th century for this to have been commissioned by a British fan. Created decades before Edvard Munch came along, it establishes the spooky magic of the north as a new territory for art.
• National Gallery, London.
Image of the week

Mark Neville’s new book, Fancy Pictures – featured on the site this week – contains images from his series Deeds Not Words, for which he travelled to Corby to document a town coping with the trauma of birth defects caused by toxic waste. It’s another of his socially engaged projects, which have taken place everywhere from Scotland to Helmand and Pittsburgh.
