Abstract
The objective of this paper is to clarify the way of rock arrangement of Soeki Katsumoto (1810-1889), also called Donketsu, a garden designer of Ohmi region. Firstly, the rock gardens that he had drawn in his garden-making treatise were analyzed. The results were as follows. 1) Verticality had been expressed through the specific proportions and the placement of the main rocks. 2) The secondary rocks with their shapes horizontal had made up contrast with the main figures' verticality. Then, the rocks of his three built works were examined. Expression of verticality was recognized in two gardens, but contrast with horizontal rocks was made up in one case.
