The Jung-hsi Studio Ni Tsan (A.D. 1301-1374) Yuan Dynasty Ink on paper. Hanging scroll. 74.7 x 35.5cm. Ni Tsan was a native of Wu-hsi, Kiansu. His style name was Yuan-chen and his sobriquet Yun-lin. One of the Four Masters of the Yuan dynasty, Ni was noted for his landscapes, bamboos and rocks. Executed when the artist was 72 years old, the colophon states that this painting was first given to Ni's friend Pei-hsuan, who kept it for three years and then gave it to his physician friend Chung-jen asking the artist to inscribe a poem. Jung-hsi was the name of Chung-jen's residence. The brushwork in the painting is especially bland and refined, with tonal variations in the trees most carefully built up. An upright brush with point-centered energy has been employed more often than a slanted brush; and broken hemp- fibre strokes are more frequent than washes in the modeling of the rocks.
