Sangaku Notebook A5, A6, A7 and Wallet, 2008


Japanese Temple Geometry : SANGAKU
We created this series of wallets and notebooks with an original pattern for Opening Ceremony. Japanese Temple Geometry: Sangaku The patterns printed on these wallets and notebooks are redrawn from traditional Japanese geometry. During the Edo period (1603-1867) Japan was cut off from the western world. But learned people of all classes, from farmers to samurai, produced theorems in Euclidean geometry. These theorems appeared as beautifully colored drawings on wooden tablets which were hung under a roof in the precincts of a shrine or temple. The tablet was called a Sangaku which means a mathematics tablet in Japanese. Many skilled geometers dedicated a Sangaku in order to thank the gods for the discovery of a theorem. The proof of the proposed theorem was rarely given. This was interpreted as a challenge to other geometers, "See if you can prove this."
