Please answer the following question: Information:  - Caspar David Friedrich (5 September 1774  7 May 1840) was a 19th-century German Romantic landscape painter, generally considered the most important German artist of his generation. He is best known for his mid-period allegorical landscapes which typically feature contemplative figures silhouetted against night skies, morning mists, barren trees or Gothic or megalithic ruins. His primary interest as an artist was the contemplation of nature, and his often symbolic and anti-classical work seeks to convey a subjective, emotional response to the natural world. Friedrich's paintings characteristically set a human presence in diminished perspective amid expansive landscapes, reducing the figures to a scale that, according to the art historian Christopher John Murray, directs "the viewer's gaze towards their metaphysical dimension".  - Adolph Friedrich Erdmann von Menzel (December 8, 1815February 9, 1905) was a German Realist artist noted for drawings, etchings, and paintings. Along with Caspar David Friedrich, he is considered one of the two most prominent German artists of the 19th century, and was the most successful artist of his era in Germany. First known as Adolph Menzel, he was knighted in 1898 and changed his name to Adolph von Menzel.  - Studio Wall ( 1872 ) is an oil painting by the German artist Adolph Menzel , now in the collection of the Hamburger Kunsthalle . It is considered one of the `` masterpieces of Menzel 's maturity '' , and the artist deemed it his best painting . The painting depicts a red colored wall of the artist 's studio at night , upon which are hung a series of plaster casts illuminated from below . The casts include portrait busts , death masks and life masks of friends of the artist , children , classical personae such as Dante , Schiller , and possibly Goethe or Wagner , a dog , and male and female torsos ; art historian Werner Hofmann saw this assemblage as a conscious blurring of `` the dividing line between fame and anonymity . '' Numerous commentators have noted that the array of dramatically lit casts `` convey an uncanny impression of quasi-animateness . '' Studio Wall was preceded by a work of the same title painted in 1852 , an oil on paper now in the Alte Nationalgalerie in Berlin . That painting features casts of two arms and a separate hand , the arms arranged so as to suggest a relationship to a body from which they have been removed . Studio Wall is also seen as related to Menzel 's larger painting Iron Rolling Mill ( 1872 -- 1875 ) , for which it may have served as a study in dramatic lighting , yet it has greater import than that of a merely preparatory exercise , and may have functioned as a kind of memorial : the central death mask is that of the artist 's friend Friedrich Eggers , the first critic sympathetic to Menzel 's work . Eggers died in August 1872 , and the painting is dated from October of that year . A contemplation on the transience of life , Studio Wall is also a bravura piece of alla prima painting . Interpretations of the work vary greatly . For art historian Julius Meier - Graefe , Studio Wall was a harmonious example of pictorial unity ; to the contrary , Hofmann saw the painting as a `` coded manifesto '' , a rejection by Menzel of academic canons in favor of an aesthetic that...
