Friedrich worked for two years on this, ultimately his most famous work. The composition is divided horizontally into land, sea, and sky with a clear simplicity that shocked his contemporaries. A monk stands, bareheaded, on the shore. Seagulls circle around him. The lonely figure faces the leaden blackness of the immeasurably vast sea. The grey band of cloud over the water surprisingly gives way to blue sky along the top edge of the picture. No artistic composition had ever been as uncompromising as this: the main space of the picture seems like an abyss of some kind; there are no boundaries, there is nothing to hold on to, just a sense of floating between night and day, between despair and hope. In 1810 Heinrich von Kleist put into words, as no other could, the magical fascination of this painting: “Nothing could be more sombre nor more disquieting than to be placed thus in the world: the one sign of life in the immensity of the kingdom of death, the lonely center of a lonely circle. With its two or three mysterious objects the picture seems somehow apocalyptic, like Young’s Night Thoughts, and since its monotony and boundlessness are only contained by the frame itself, contemplation of this picture gives one the sense that one’s eyelids have been cut away.”
