Ch: chaoyang duiyue. A Zen painting subject depicting a priest sewing in the morning sun (Jp: chōyō 朝陽) and another reading a sutra by the reflection of the moon (Jp: taigetsu 対月). The theme is derived from a Song poem attributed to Wang Fengchen 王逢辰: "In the morning sun I mend my torn robe, by moonlight I practice my sutras," which sums up the simple nature of Zen practice. Typically the subject is rendered as a pair of hanging scrolls hung with the two monks facing inward.
The oldest extant painting on the theme is by Wu Zhuzi 無住子 (1295; Tokugawa 徳川 Art Museum, Aichi Prefecture), although there are also versions attributed to Muqi (Jp: Mokkei 牧谿; late 13th century; Dōmoto 堂本 Collection, Kyoto) and Yintuoluo (Jp: Indara 因陀羅; private collection). Two Japanese examples are particularly well-known, one by Chūan Shinkō 仲安真康 (mid-15th century; Tokyo National Museum) and the other a pair of hanging scrolls attributed to Kaō 可翁 (early 14th century; Boston Museum of Fine Arts and Cleveland Museum, USA).
