Medieval Rinzai was also invigorated by a series of Chinese masters who came to Japan during the Song dynasty, such as Issan Ichinei (1247–1317). Issan influenced the Japanese interest in Chinese literature, calligraphy and painting. The Japanese literature of the Five Mountains ("Gozan Bungaku") reflects this influence. One of his students was Musō Soseki, a Zen master, calligraphist, poet and garden designer who was granted the title "national Zen teacher" by Emperor Go-Daigo. The Zen monk poets Sesson Yūbai and Kokan Shiren also studied under Issan. Shiren was also a historian who wrote the Buddhist history "Genkō shakusho".
