【說明】

山本由定（1863-1934），又名繇定，號岐山、竟山，以號行，是湯川秀樹一家手足的書法教師。早年師事日下部鳴鶴（1838-1922）等名家，並在日下部的引介下向楊守敬（1839-1915）學習。
秀樹自學齡前便在山本竟山門下習字，由「永字八法」啟蒙，逐步進入楷、行、草諸體，至第三高等學校時方始學習隸書。從秀樹後來的回憶可知，他之所以能自信落筆、書以贈人，正是因為受山本竟山訓誨建立了扎實功底，使書寫成為他優雅表達心意的方式。
本作可見其融會日下部與楊守敬書風之面貌。
 

​【Description】

Kyouzan Yamamoto (1863–1934) served as the calligraphy instructor for Hideki Yukawa and his siblings. Trained early on under leading calligraphers such as Meikaku Kusakabe(1838–1922), Yamamoto was later introduced by Kusakabe to the eminent Qing scholar Yang Shoujing (1839–1915).

Hideki began studying calligraphy under Yamamoto even before reaching school age, starting with the foundational Eight Principles of the Yong Character and gradually advancing through regular, running, and cursive scripts; it was not until his years at the Third Higher School that he first encountered clerical script. In later recollections, Hideki attributed his confidence in writing and in presenting calligraphy to others to the rigorous training he received from Yamamoto, which provided him with a solid foundation and allowed calligraphy to become a graceful means of personal expression.

The brushwork of this work reflects the style he developed through the synthesis of Kusakabe’s and Yang’s calligraphic traditions.
