A lecture on how simple geometric shapes have become symbols of the universe in different eras. Circle, sphere, cone, polyhedron - shapes through which humanity has tried for centuries to describe the structure of the world. In his unique series, Viktor Troitsky discusses the history of symbolism. The central motif of the series is Albrecht Dürer's famous "Melancholia I," in which geometric shapes are presented as symbols of human nature, time, and the universe. These lectures are for those interested in philosophy, history, and art. The starting point of the discussion will be the works of Albrecht Dürer, where one can find several "hyper-shapes," that is, visual solutions through which a person tries to convey the world as a whole. These include the sphere, cone, polyhedron, and other structures that, upon careful examination, reveal rich meaning. Our website will tell you where to go in Moscow today.
