The whereabouts of Schinkel’s painting "Landschaft mit Pilger" (Landscape with Pilgrim) where already unknown in 1862 and it is still considered lost. In 1823 Wilhelm Ahlborn (1796-1857) copied five Schinkel landscapes by commission of the consul Joachim Wilhelm Wagener in Berlin, among them also the “Landschaft mit Pilger“. Today this painting is in possession of the Pushkin Museum in Moscow. In a review of the Ahlborn copy Ernst Riehn mentioned in his dissertation from 1940, that a second copy after Schinkel was in possession of the family Heinrich (-Unus) in Berlin: This work is the "Kopie 2" by an unknown painter, it was erroneously exhibited as the original Schinkel work in exhibitions at Cassirer in Berlin in 1932 and in 1981 in Charlottenburg Castle, Berlin. It was described in the catalogs as follows. “Being the only known copy of the renowned Schinkel painting, the picture [..] possesses great value.“ (Transl. from Börsch-Supan 2007, p. 361).
"The composition belongs to the Schinkel paintings that breathe the poetic spirit of early Romanticism. As it is the case with many of Friedrich’s paintings, fore- and background are strictly separated. The oak tree, rooted with little stability on the brink, spreading its branches roof-like above the ground, frames the view into a misty-eyed world, despite all yearning, it is only reachable by the eye. The monk sitting on a rock, holding a crucifix, a motif unusual for Schinkel, combines the thought of religious expectation with the fascination for nature and architecture, both are reminiscences of Italy. The domed structure is clearly reminiscent of St. Peter in Rome. [..] Schinkel’s ambitions to bring meaningful motifs in close connection – the monk, the fountain on the terrace, the cupola, the setting sun, is supported by the landscape‘s dream-like character. A reminiscence of Claude Lorrain seems intended. The painting is dated around 1813; however, due to the slightly ‘hard‘ style it is possible that it was made a little earlier [..]."
