their culture through the mad xenophobia of the Third Reich. In 1969, at Galerie am Kaiserplatz, Karlsruhe, he presented his first single exhibition "Besetzungen (Occupations)" with a series of photographs of controversial political actions. Painting and sculpture Kiefer is best known for his paintings, which have grown increasingly large in scale with additions of lead, broken glass, and dried flowers or plants. This results in encrusted surfaces and thick layers of impasto. By 1970, while studying informally under Joseph Beuys at Kunstakademie Düsseldorf, his stylistic leanings resembled Georg Baselitz's approach. He worked with glass, straw, wood and plant parts. The use of these materials meant that his art works became temporary and fragile, as Kiefer himself was well aware; he also wanted to showcase the materials in such a way that they were not disguised and could be represented in their natural form. The fragility of his work contrasts with the stark subject matter in his paintings. This use of familiar materials to express ideas was influenced by Beuys, who used fat and carpet felt in his works. It is also typical of the Neo-Expressionist style. Kiefer returned to the area of his birthplace in 1971. In the years that followed, he incorporated German mythology in particular in his work, and in the next decade he studied the Kabbalah, as well as Qabalists like Robert Fludd. He went on extended journeys throughout Europe, the US and the Middle East; the latter two journeys further influenced his work. Besides paintings, Kiefer created sculptures, watercolors, photographs, and woodcuts, using woodcuts in particular to create a repertoire of figures he could reuse repeatedly in all media over the next decades, lending his work its knotty thematic coherence. Throughout the 1970s and early 1980s, Kiefer made numerous paintings, watercolors, woodcuts, and books on themes interpreted by Richard Wagner in his four-opera cycle Der Ring des Nibelungen (The Ring of the Nibelung). In the early 1980s, he created more than thirty paintings, painted photographs, and watercolors that refer in their titles and inscriptions to the Romanian Jewish writer Paul Celan's poem "Todesfuge" ("Death Fugue"). A series of paintings which Kiefer executed between 1980 and 1983 depict looming stone edifices, referring to famous examples of National Socialist architecture, particularly buildings designed by Albert Speer and Wilhelm Kreis. The grand plaza in To the Unknown Painter (1983) specifically refers to the outdoor courtyard of Hitler's Chancellery in
