Books and paintings are homogeneous but different. The painter looked at Jialing River, saw its rough waves and pursued its essence. Huai Su, a calligrapher, was impressed by the sound of Jialing River at night. When dancing the sword, the world is low, and Zhang Xu looks at its charm and is fascinated by the frost.
The homology of calligraphy and painting is a calligraphy and painting term in China. China's paintings are closely related to China's calligraphy, and their emergence and development complement each other. In the history of painting, the so-called "He Tu Luo Shu" of pre-Qin philosophers is the basis of the homology of painting and calligraphy.
Zhang Yanyuan's "History of Famous Paintings, Narrating the Origin of Paintings" in the Tang Dynasty said: "You have four eyes, you look up and you bow your head. Because the traces of birds and turtles determine the shape of the characters, it is naturally impossible to hide its secrets, so it rained heavily; Ghosts can't hide from shapes, so ghosts cry at night. At the right time, calligraphy and painting are the same, without division, just like the beginning of the elephant system. There is no way to convey its meaning, so there are books; There is no way to see its shape, so there are paintings. "
This is the earliest theory of "painting and calligraphy are homologous". Yin Qi's ancient prose system is the coexistence of calligraphy and pictures. Zheng Wuchang, a close friend, said, "This is an era of calligraphy and painting".
