Mìchuán yǎnkē Lóngmù lùn 秘傳眼科龍木論

Secretly-Transmitted Ophthalmological Treatise of [Bodhisattva] Nāgārjuna attributed to 龍樹 Nāgārjuna (Lóngshù / Lóngmù 龍樹/龍木) via the Daoist persona 葆光道人 Bǎoguāng Dàorén (“the Daoist of Treasured Brightness”), Míng-period compiler.

About the work

A ten-juǎn compilation that is the canonical late-imperial form of the Lóngmù lùn 龍木論 ophthalmological tradition — the principal pre-modern Chinese ophthalmology that conserves the South-Asian Buddhist-medical inheritance, attributed by pseudepigraphy to the Mahāyāna philosopher 龍樹 Nāgārjuna (Sanskrit nāga-arjuna “Dragon-Arjuna”; Chinese variously rendered 龍樹 Lóngshù, 龍勝 Lóngshèng, or in this work’s title 龍木 Lóngmù — orthographically variant for 龍樹). The work codifies the classical ophthalmological taxonomy of seventy-two diseases (七十二般) — twenty-three “outer obstructions” (外障 wàizhàng) plus forty-nine inner-obstruction / mixed conditions, expanded by some accountings to seventy-two — together with the five-wheel (五輪 wǔlún: wind-wheel 風輪 / blood-wheel 血輪 / flesh-wheel 肉輪 / qì-wheel 氣輪 / water-wheel 水輪) and eight-quadrant (八廓 bākuò) symbolic schema, the seventy-two-question Q&A in wèn / dá form, and a vast diagnostic-prescription apparatus. The text preserves South-Asian-origin operative procedures (cataract couching, pterygium-cutting, blade-cautery, fine-needle bloodletting) within an otherwise Sino-Daoist framework. Juǎn 1–4 contain the doctrinal core (“Lóngmù zǒnglùn” 龍木總論, the審的歌 “Songs of Examined Targets,” the five-wheel and eight-quadrant verses, and the seventy-two-disease catalogue); juǎn 5–8 contain the named-syndrome catalogue (青風內障, 綠風內障, 烏風內障 etc.); juǎn 9–10 contain appendices including the Bǎoguāng dàorén yǎnkē Lóngmù jí 葆光道人眼科龍木集.

Prefaces

The text’s _000.txt is itself the appended Bǎoguāng dàorén Yǎnkē Lóngmù jí 葆光道人眼科龍木集 (the Daoist-author’s own integrated digest), which functions as preface, doctrinal abstract, and recapitulation in one. It opens: “Of the six sense-faculties (六識), the eye is supreme — called the sun and the moon, likened to the black pearl” (夫六識之中。以眼為上。稱為日月。喻以驪珠), and proceeds through a doctrinal exposition uniting the Buddhist liù shí 六識 (“six consciousnesses”) framework with the Sino-medical zàngfǔ / wǔlún schema. It explains that the inner pearl-membrane (the pupillary water, shénshuǐ 神水) is “pure in nature and intolerant of the slightest mote of dust” (水之性澄清。不奈纖埃), describes the five wheels and the eight quadrants as the diagnostic key, and frames the entire enterprise as a Buddhist-derived secret transmission. The use of Lóngmù 龍木 (rather than the canonical Lóngshù 龍樹) is a deliberate orthographic-mystery variant that the Daoist compiler uses to mark the work as an esoteric transmission distinct from the Buddhist canonical Madhyamaka corpus of Nāgārjuna proper.

Abstract

The Nāgārjuna attribution is pseudepigraphic and conserves a real historical kernel: South Asian ophthalmological knowledge — including the operative needling of cataract (jalauka-vidhi) and pterygium-cutting — did genuinely enter China through Buddhist translation activity, most famously through the Lóngshù pútísà yǎnlùn 龍樹菩薩眼論 (Nāgārjuna-Bodhisattva-Eye-Treatise) cited by Wáng Tāo’s KR3f0006 Wàitái mìyào 外台秘要 (752) and partially preserved in late-Táng / Sòng manuscripts (cf. Dūnhuáng manuscript fragments S.6722; see Liào Yùqún 廖育群 1990 and Hinrichs and Barnes 2013, pp. 78, 196). The present text is not that Lóngshù pútísà yǎnlùn but a much later SòngYuánMíng recompilation claiming descent from it. The standard scholarly view (中國醫籍提要; 范行準《中國醫學史略》, 1986) is that the received ten-juǎn Mìchuán yǎnkē Lóngmù lùn was compiled in the Northern Sòng (c. 11th c.), expanded in the Yuán by the still-unidentified Daoist Bǎoguāng dàorén 葆光道人 (whose layer is detachable as the Yǎnkē Lóngmù jí), and reached its received Míng form by the early 16th century, when it was first printed by 劉文泰 Liú Wéntài in the Hóngzhì 18 (1505) Tàiyīyuàn edition. The present digital text (jicheng.tw / 漢學文典) reflects a later Míng witness preserved overseas. The dating bracket here is conservatively given as 1368–1644 (Míng) on the basis of the received recension’s print transmission.

The internal structure is encyclopaedic. The opening 審的歌 “Songs of Examined Targets” set out the seventy-two-disease principle in mnemonic verse. The five-wheel / eight-quadrant doctrine is rendered both as theoretical prose and as eight-line shī-style poems for each lún and each kuò (Guānquánkuò 關泉廓, Yǎnghuàkuò 養化廓, Bàoyángkuò 抱陽廓, Chuándàokuò 傳道廓, Shuǐgǔkuò 水穀廓, Jīnyèkuò 津液廓, Qīngjìngkuò 清淨廓, Huìyīnkuò 會陰廓). The 七十二問 Míngtáng wèndá 明堂問答 section is essentially identical to the seventy-two-problem text preserved in KR3em002 Míngmù zhìbǎo — the two texts share a common Lóngmù lùn-tradition Q&A core. The named-syndrome catalogues (qīngfēng nèizhàng 青風內障 ≈ glaucoma; yuányì nèizhàng 圓翳內障 ≈ mature cataract; huáyì 滑翳 ≈ early cataract; wūfēng nèizhàng 烏風內障 ≈ pigmentary retinal disease; xióng huā nèizhàng 雄花內障; etc.) provide the most comprehensive pre-modern Chinese ophthalmological nosology. The work also preserves the operative procedures — 鉤割針鐮法 (hooking, blade-cutting, needle-pricking, sickle-cautery) — at the level of detail needed to actually perform pterygium dissection and cataract couching, with stipulations on the operator’s posture, the assistant’s role, the timing of the procedure relative to fasting and to the patient’s qì-flow, and the post-operative dressing.

Translations and research

  • No complete Western-language translation has been published. The work is, however, fundamental to the history of Chinese ophthalmology and is partially excerpted in: Hubotter, Die chinesische Medizin (1929), and in Vivienne Lo and Christopher Cullen (eds.), Medieval Chinese Medicine: The Dunhuang Medical Manuscripts (RoutledgeCurzon, 2005), which discuss the related Dūnhuáng Lóngshù pútísà yǎnlùn fragments.
  • Modern Chinese critical edition: 蔡景峰 (ed.), 《秘傳眼科龍木論校注》 (北京：人民衛生出版社, 1998), based on the 1505 Liú Wéntài Tàiyīyuàn print.
  • Background on the Indo-Buddhist transmission of ophthalmology to China: Hinrichs and Barnes (eds.), Chinese Medicine and Healing: An Illustrated History (Harvard, 2013), pp. 78, 196; Schipper, Concordance du Tao-tsang (1975), index s.v. 龍樹; Liào Yùqún 廖育群, 〈陳藏器·龍樹眼論〉, in 《中華醫史雜誌》 1990.

Other points of interest

This is the foundational late-imperial Chinese ophthalmology — the source from which all subsequent wǔlún bākuò and seventy-two-disease ophthalmologies, including KR3em002 Míngmù zhìbǎo, KR3em004 Yǎnkē mìjué, KR3em010 Shěnshì yáohán, and KR3em011 Yínhǎi jīngwēi, ultimately derive. Its operative-procedure descriptions are also the most detailed pre-modern Chinese ophthalmological surgical instructions surviving in any single text.

The orthographic Lóngmù 龍木 (“Dragon-Tree” with the “tree” written as the simple mù 木 rather than the full shù 樹) is iconic for the tradition: it is the form used on cover-pages and title-leaves to mark the work as a Daoist-Chinese reception of Nāgārjuna’s name, distinct from the Buddhist canonical 龍樹 used in T-Canon translations.
