Pu Tzu once mentioned, "Classical calligraphy has a pivotal role in every calligraphy studies. The synchronization of paper, ink, brush, the mind and words express the calligrapher's interpretation and attachment towards life and nature. The process of writing characterizes one's mind and composure, yet I wish to reach a breakthrough by creativity." Pu Tzu's entire life had been devoted to ink art by exploring a range of aspects through structure, ink, colours and forms. Calligraphy in Cursive Script (Lot 643), an enormous full frame work completed in vermilion, is extremely rare in quantity among Pu Tzu's signature works. The depth of Pu's has been demonstrated through the meticulous composition and techniques used in this work. The poem depicts a vividly animated autumn scene of a banana tree outside the window. The season is highlighted by vermilion. Curvaceous lines demonstrate the roughness and sturdiness comparable to a lush and ancient vine. Dried and fragmented traces of ink enliven the work as autumn leaves stirred up by a gust of wind. The monumental size of the work in red augments the theatrical impact of expressive cursive script, as the movement of the body and brush of Pu Tzu imprints in the minds of viewers. Similar impact could be experienced with paintings by Japanese Gutai artist Shiraga. As the rhythmic beats echo with the vermilion lines till the end, casual patterns of black ink dots gently bring the eye towards the signature on the right, leading the theatrical symphony to an end. Chen Yong-Mo once compared Pu Tzu's calligraphy to an evergreen autumn vine that is strong and lush throughout the year, and that his skills reached beyond traditional Song and Ming calligraphers. Ancient vine has traditionally been deemed as the highest-level of recognition given to a calligrapher. Hence, an ancient and fecund vine would best depict Pu Tzu's life of devotion towards creativity from classical calligraphy.
