Two Men Contemplating the Moon, 1825-30
You can see that these two figures are in communion with nature. They are identified on the right as Friedrich and his friend and student August Heinrich (1794-1822). The fascination of the moon was great among the German Romantics, who viewed the subject as an object of pious contemplation. This is the third version of one of Friedrich's most famous compositions, composed during Heinrich's lifetime (1819, Gemäldegalerie, Dresden) and the second soon after his death (around 1824, Alte Nationalgalerie, Berlin).
