Monk by the Sea

Caspar David Friedrich, Monk by the Sea, c. 1809, oil on canvas, 43" x 67 1/2" /110 x 171.5 cm (Nationalgalerie, Staatliche Museen, Berlin)

"Like Constable, Friedrich drew on the natural world around him, often returning to the same area again and again. Unlike the English painter’s more scientific or naturalist approach, though, Friedrich condensed the image so as to communicate an exact emotion. As he put it, “a painter should paint not only what he sees before him, but also what he sees within himself.” It is this inward reaching project, using colour and form to reveal emotional truths, that singles him out as one of the greatest and most innovative painters of his age: a true Romantic."
