"Friedrich, with his somewhat stiff and diffuse but highly poetic manner, was the first artist — in painting as a whole, but more especially in landscape painting — who ever assailed and shook up the philistines of Dresden. There had been a great stir when one of his paintings, a crucifix on a rock beneath dark fir trees and against the dying glow of an evening sky, had given rise to a literary controversy conducted on Friedrich's behalf by his friend Gerhard von Kügelchen [Kügelgen] and on the opposing side by a prosaic dilettante, a certain Herr von Ramdohr — to the latter's eventual discomfiture."
