Katagiri, Yuji Circle, triangle, and square: trinity of geometry in the architecture of Aldo Rossi. (English) Zbl 1401.00031 J. Geom. Graph. 22, No. 1, 129-137 (2018). Summary: This paper is to reveal geometric development of the architectures of Aldo Rossi in 1960-70 through relationships between Rossi and The Circle, Triangle, and Square, the picture of Zen, drawn by the Japanese artist Sengai-Gibon. First, we analyze Rossi’s works in the 1960s by extracting the three geometries. Then, we show that Rossi applied his impression of Sengai to design for important works such as Modena Cemetery and Teatro del Monde. Finally, the paper elucidates the trinity of geometry inherited from Sengai.
