Zhao Yiguang was a Ming dynasty scholar and calligraphy theorist. Publicly available information about his life is limited, and both his dates of birth and death and his native place remain uncertain. Judging from his extant works, he devoted sustained attention to the study of characters and to calligraphy theory, with his thinking centering on character forms, brushwork, and the tradition of writing. The library holds two of his works, Hanshan Zhou Tan and an unannotated edition of the same title, which may be regarded as his representative writings. Hanshan Zhou Tan discusses, in the form of random notes, the origins and development of calligraphy, brush use and character structure, and evaluations of steles and model calligraphies; it also touches on the explanation of characters and approaches to learning calligraphy. Its language is concise and at times offers distinctive views, reflecting a scholarly orientation that values evidence and norms. The book is often classified under Eastern philosophy, though it is in fact closer to a work combining traditional art theory with writing practice, and it retains some reference value for later students of calligraphy and for understanding Ming dynasty views on calligraphy.
