philosophy of writing and arche-writing found their way into deconstructivist memorials. Daniel Libeskind envisioned many of his early projects as a form of writing or discourse on writing and often works with a form of concrete poetry. He made architectural sculptures out of books and often coated the models in texts, openly making his architecture refer to writing. The notions of trace and erasure were taken up by Libeskind in essays and in his project for the Jewish Museum Berlin. The museum is conceived as a trace of the erasure of the Holocaust, intended to make its subject legible and poignant. Memorials such as Maya Lin's Vietnam Veterans Memorial and Peter Eisenman's Memorial to the Murdered Jews of Europe are also said to reflect themes of trace and erasure. Constructivism and Russian Futurism Another major current in deconstructivist architecture takes inspiration from the Constructivist and Russian Futurist movements of the early twentieth century, both in their graphics and in their visionary architecture, little of which was actually constructed. Artists Naum Gabo, El Lissitzky, Kazimir Malevich, and Alexander Rodchenko, have influenced the graphic sense of geometric forms of deconstructivist architects such as Zaha Hadid and Coop Himmelb(l)au. Both Deconstructivism and Constructivism have been concerned with the tectonics of making an abstract assemblage. Both were concerned with the radical simplicity of geometric forms as the primary artistic content, expressed in graphics, sculpture and architecture. The Constructivist tendency toward purism, though, is absent in Deconstructivism: form is often deformed when construction is deconstructed. Also lessened or absent is the advocacy of socialist and collectivist causes. The primary graphic motifs of constructivism were the rectangular bar and the triangular wedge, others were the more basic geometries of the square and the circle. In his series Prouns, El Lizzitzky assembled collections of geometries at various angles floating free in space. They evoke basic structural units such as bars of steel or sawn lumber loosely attached, piled, or scattered. They were also often drafted and share aspects with technical drawing and engineering drawing. Similar in composition is the deconstructivist series Micromegas by Daniel Libeskind. Contemporary art Two strains of modern art, minimalism and cubism, have had an influence on deconstructivism. Analytical cubism had a sure effect on deconstructivism, as forms and content are dissected and viewed from different perspectives simultaneously. A synchronicity of disjoined space is evident in many of the works of Frank Gehry and
