Shì Guànxiū 釋貫休 (832–912), originally zì Déyǐn 德隱, later honorifically Chányuè dàshī 禪月大師, of Lánxī xiàn 蘭溪縣 in Wùzhōu (modern Zhèjiāng). The most celebrated late-Táng / Five-Dynasties Buddhist monk-poet, calligrapher, and painter — particularly noted for his iconographic Shíbā lóuhàn / Sixteen Arhats image-series, which became foundational for East Asian Buddhist lóuhàn (arhat) iconography. CBDB id 94183 confirms 832–912.
Guànxiū took the tonsure as a child at Jīnhuáshān 金華山 in Dōngyáng and trained as a poet and calligrapher. His poetic career proceeded through three phases: (1) early Jiāngnán phase, with extensive correspondence in the late-Táng poetic network (he addresses Luó Yǐn 羅隱 羅隱, Lú Guīméng 陸龜蒙, Pí Rìxiū 皮日休, and others); (2) middle phase at Lóngxìngsì 龍興寺 in Jīngmén (Húběi) in the 890s, when Wú Róng 吳融 吳融 (banished south as Hànlín drafter under Zhāozōng) regularly visited his cell — the friendship issuing in Wú’s famous preface (the Chányuè jí xù, dated Jǐwèi = 899) which is the principal contemporary critical statement on Guànxiū’s poetics. The volume Wú prefaced was originally titled Xīyuè jí 西岳集; (3) late phase in Former-Shǔ under Wáng Jiàn 王建 (r. 907–918) at Chéngdū, where he received the styled honorific titles Lónglóu dàizhào 龍樓待詔, Míngyīn biànguǒ gōngdé dàshī, Liǎngjiē sēnglù 兩街僧錄, and Chányuè dàshī 禪月大師, along with food-tax revenue from 8000 households — the highest court honors granted a Buddhist monk in the late-Táng / Five-Dynasties Shǔ. From this honorific the collection took its later title.
His poetic style — sharper-edged and more imagistically inventive than the more orthodox-classical Qíjǐ 釋齊己 釋齊己 — distinguishes the Chán strand of late-Táng monastic poetry from the Báilián / classical strand. His Sixteen Arhats paintings (now lost as autographs but preserved in Sòng-period engraved copies and Japanese Heian-era funpon tradition) feature gaunt, strange-faced “shēnmù gāobí” (deep-eyed, high-nosed) Central Asian–inspired figures whose iconography reaches into the Jūroku Rakan-zu tradition in Japan. His extant collection is KR4c0110 Chányuè jí (SBCK 25-juǎn).
