|  Sutra cylinder. A container for the Buddhist sutras 
placed in the sutra mound kyouzuka 経塚: cylinders of circular, hexagonal 
or octagonal shape, with fitted lids either flat or cap-shaped. Various materials 
are used, including copper sheets, cast copper, cast iron and pottery. Some have 
inlaid copper mirror bottoms. It is generally true that examples from the Heian 
period are larger and longer than those of the Kamakura and Muromachi periods. 
Kyozutsu often bear an inscription and date on the base. |
