Caspar David Friedrick's 
Nature, as immanent God, requires no personification, other than its organic and inorganic subjects and objects--its things visible to the eye, which symbolically express through their forms the truth of nature, which is to say, divine truth.

For Freidrich, landscapes are temples; his paintings themselves, divine altarpieces. His reverential mood demands the silence appropriate to sacred places filled with the Divine presence.
