Shot at Nanzen-Ji, a Zen Buddhist temple in Kyoto. There was a Japanese style water place in a corner of the precinct. The water is tapped from the bamboo to the stone basin. The place was surrounded by the silence and the sound of the bamboo hitting the stone was echoed once and away.
A square hollow was made on the stone cylinder. And the shape reminded me a coin. The coin was big. If the primitives used coins, their coin could be shaped like that.
