perhaps the most important surviving work by the master is the so-called "long scroll of landscapes" ("sansui chokan"): a 50-feet (15 meters) scroll depicting the four seasons in the sequence spring—summer—autumn—winter. as is usual for the period and the work of sesshū's teacher tenshō shūbun, style and technique are heavily influenced by song-dynasty chinese paintings, in particular the works of xia gui. however, sesshū alters the chinese model by introducing more pronounced contrast between light and shadow, thicker, heavier lines, and a flatter effect of space. there are two other large landscape scrolls attributed to sesshū. the smaller "four seasons" scroll ("short scroll of landscapes") exhibits qualities similar to those of "sansui chokan", only featuring somewhat more free technique. "view of ama-no-hashidate", painted shortly before the artist's death, is a radical departure from the chinese tradition: the painting presends a realistic bird's eye view of a particular landscape.
