Yanshan Inscription is associated with Mi Fu, one of the Four Great Masters of Song calligraphy. Mi Fu?s writing is admired for its lively movement, shifting rhythm, and expressive individuality. This work displays a free and spirited brush manner, with characters that vary in size, density, and momentum. The result is a vivid example of Mi Fu?s calligraphic personality: elegant, unconventional, and full of motion.
