"Friedrich has now given a task: someone wants to have two pictures - one representing an Italian landscape in all its luxuriant magnificent beauty, the other - the awe inspiring nature of the north. It is the second that Friedrich has undertaken to paint; he does not know what it will be. He is waiting for the moment of inspiration, which frequently comes to him, as he told me, in a dream."
