Description:

Sangaku (lit. “calculation plaque”) are a type of votive tablet from the Edo period. Japanese mathematicians created sangaku by painting geometrical puzzles and theorems onto wooden boards. Those boards were then dedicated to shrines and temples. 

This is the second-oldest sangaku in Saitama City. It was donated to the Akiha-jinja Shrine of Nakakugi in 1840 by two students of the Sekiryu school of mathematics. It depicts two geometry calculation problems and a scene of a Japanese mathematics lesson using sangi counting rods.
