Caspar David Friedrich (5 September 1774 – 7 May 1840) was a 19th-century German Romantic landscape painter, generally considered the most important German artist of his generation.

„What the newer landscape artists see in a circle of a hundred degrees in Nature they press together unmercifully into an angle of vision of only forty-five degrees. And furthermore, what is in Nature separated by large spaces, is compressed into a cramped space and overfills and oversatiates the eye, creating an unfavorable and disquieting effect on the viewer.“
