芥子園重訂本草綱目:a reprint version in Qing Dynasty of the Bible of Traditioanl Chinese Medicine
Ben-Cao-Gang-Mu (本草綱目) is one of the most famous encyclopedia for Chinese Traditional Medicine, known as the “Compendium of Materia Medica” for Chinese Medicine. It has tremendous historical significance in Chinese Medicine, and it is “the highest academic achievement among all ancient Chinese Medicine literature” [1] up to the 16th century. The original version of Ben-Cao-Gang-Mu was written, summarized and edited by famous herbalist, physician and pharmacologist in Ming Dynasty, Li Shizhen (李时珍) in the late 16th century during Ming Dynasty of China. The book had 52 volumes in total, and was first published in 1596 during Ming dynasty in Nanjing, China.[2]The version of the book demonstrated here is a Re-print version of the original Ben-Cao-Gang-Mu published in 1657 during Qing Dynasty, nearly 60 years after the first publication. It was published by Li-Yu (李渔), a famous playwright and novelist in Qing dynasty, who used the name of the mansion he lived in “Jie-Zi-Yuan” (芥子園) as the publisher name for the re-print.
This particular version of Ben-Cao-Gang-Mu is named as Jie-Zi-Yuan-Chong-Ding-Ben-Cao-Gang-Mu (芥子園重訂本草綱目), and is especially intriguing not only because of it allows us to understand more about the development of traditional Chinese Medicine, more importantly, the re-print itself provides invaluable information about the history of publishing, copyright and authorship in China during the Qing Dynasty. This book was also collected by Penn Library around early 1900s, and its circulation history at Penn is also very interesting as well.
Historical Significance
Historical Significance of Ben-Cao-Gang-Mu in Chinese Traditional Medicine
Ben-Cao-Gang-Mu (本草綱目) is one of the most comprehensive Medicine Books ever written in the history of Traditional Chinese Medicine. The original author, Li-Shi-Zhen (李时珍) completed the first draft in 1578 during the Ming Dynasty when China was governed by emperor Wanli (万历)[3], and it took Li-Shi-Zhen nearly 27 years to finish compiling and editing the book to its final published version.[3]. Ben-Cao-Gang-Mu has unique historical significance in Chinese Traditional Medicine because of its comprehensive medical literature coverage, and also the unique classification system developed to better classify, and understand the medical properties of objects with an evidence-based approach.
Comprehensive Medical Knowledge coverage through extensive reading
Ben-Cao-Gang-Mu is an encyclopedic work heavily based on the results and conclusions from previous medical literature in Chinese Traditional Medicine up until the 16th century. In order to have sufficient knowledge to complete such a huge project, the author Li-shi-zhen reviewed probably “more than 800 different sources” [4], extensively read and reviewed numerous previous medical literature, especially the ones on herbal medicine.
Before citing the literature in his book, Li-Shi-Zhen evaluated the conclusions in previous literature through comparison with his own observation and practice experience in medicine, making the decision based on an empirical approach [5]. Among all the medical literature that was cited in Beng-Cao-Gang-Mu, Herbal medicine work was most abundant and most frequently cited. There are 42 kinds of Herbal Medicine work cited in Ben-Cao-Gang-Mu, and 9 of them were books written in the same dynasty (Ming Dynasty), including 3 of Li-Shi-Zhen’s own work, as well as 6 other books: Ben-Cao-Fa-Hui本草发挥，Ben-Cao-Ji-Yao本草集要，Shi-Wu-Ben-Cao食物本草，Shi-Jian-Ben-Cao食鉴本草，Ben-Cao-Meng-Quan本草蒙筌，Ben-Cao-Hui-Bian本草汇编.[6]
If Ben-Cao-Gang-Mu is published today, it would be the “medical review” article we get background knowledge. The idea behind a “review” and Ben-Cao-Gang-Mu is the same: a comprehensive compilation and careful selection of knowledge from previous work based on extensive reading. Through extensive reading, Li-Shi-Zhen was able to review numerous previous medical literature to be able to have sufficient background knowledge to ensure the credibility of the content written in Ben-Cao-Gang-Mu. As a physician and a herbalist himself, he also had the opportunity to have the most up-to-date information in the medical field through his own medical education as well as his practicing experiences, which enabled him to examine the credibility of previous knowledge and filled in the gap between previous and present work through comparative reading and critical thinking.
Innovative classification system for medicine
Another key feature of Ben-Cao-Gang-Mu that contributes to its historical significance is innovative classification system of the medical objects. Ben-Cao-Gang-Mu has included 11,096 medical treatment recipes with 1,094 plant-based drugs, 276 mineral-based drugs, and 444 anima material-based drugs for different diseases[6]. It also features 1892 different medical objects, dividing them into 16 outlined classes and further into 60 sub-class categories . The Chinese Medical work had limitations in the number of medical objects covered: for example, in ‘‘Shen Nong Ben Cao Jing”, another famous Chinese medicine encyclopedia that was written back in the Han Dynasty, which was 6 dynasties before the Ming Dynasty), it only included 365 medical objects [1]. The reason why Li-Shi-Zhen was able to cover such a large number of medical objects in Ben-Cao-Gang-Mu is that he added additional medical objects found in regions that were not part of the Chinese Empire before Ming Dynasty [7], as well as the medical materials and objects that were imported from foreign countries, such as jasmine, camphor, and tulips. These materials and objects entered China probably through trading via the silk-road, which was a commercial trading network connecting the east to the west that was established in Han Dynasty, and continued through the Ming Dynasty. Through commercial trading and exchange with foreign countries for about 6 dynasties, there must be more novel medical object imported and exchanged through the trading, so that’s probably why in Ben-Cao-Gang-Mu, more medical objects were documented than previous work.
Besides a more comprehensive range of medical objects listed, the system to classify these medical objects is also ground-breaking in the history of Traditional Chinese Medicine, and also drives the development of Modern Chinese Medicine. Before Beng-Cao-Gang-Mu, the way medical materials and objects were classified mainly followed the classification system described in “Shen Nong Ben Cao Jing”, known as a “Three-Grade Classification”[6]. All the medical objects were classified as either high, medium or low grade according to their toxicity, properties, medical applications and efficacies [1]. However, in Beng-Cao-Gang-Mu, Li-Shi-Zhen developed a much more detailed and empirical classification system through dividing the major classes of medical objects further into different sub-categories according to their medical properties and treatment efficacies. For example, within the class of herbs, Li-Shi-Zhen further classified them into: mountain, fragrant, marshland, poisonous, aquatic, stone herbs and moss[4]. This sub-classification of herbs is based on their size, structures, natural habitats, fragrance properties and medical effects. Compared to the general classification system used in “Shen Nong Ben Cao Jing”, which only has three categories and does not differentiate medical objects based on their individual properties, Li-Shi-Zhen’s classification in Ben-Cao-Gang-Mu is based on more comprehensive research on the properties and background of these herbs, which enables him to take more information into consideration to develop a more accurate classification system.
This classification approach is also significant in the development of modern scientific thinking in China. The classification is not simply based on observation of the difference in object morphology, in addition to that, it incorporates evidence from previous documented use of medical object, reported efficacies and physician Li-Shi-Zhen’s own judgement from his medical practice, addressing the subtle differences among different medical objects. This empirical approach [3] demonstrates an early form of evidence-based writing and critical thinking skills that play an important role in scientific research today.
Promotion of Chinese Medicine in the Ming Dynasty
The Ming Dynasty was the second last imperial dynasty of China, lasted from 1368 to 1644, ruled by 16 emperors from Hongwu Emperor (real name Zhu Yuanzhang), who established the Ming Dynasty, to Chongzhen Emperor, the last emperor in Ming Dynasty.
During the Ming Dynasty, the highly centralized government structure provided great social stability, which led to the flourishment of both artistic and intellectual inspirations [8]. The emperor, as well as the governors of states and provinces (who were the relatives of the emperor), were all dedicated in starting an initiative to promote medicine and healthcare by actively pushing the compilation and publication of medical literature, either by themselves, or through collaborations with certified physicians[6].Examples of medical works published under this initiative include Jiu-Huang-Ben-Cao (救荒本草) by state governors Zhu su and Zhu Quan.
History of Original Authorship, copyright and Reprint
History of Authorship
Li-Shi-Zhen (1518-1593) finished his medical education in his twenties, and start working a medical official and physician in the medical institution after that. The medical institution was located within a palace of the state governor named Zhu Ying Xian (also known as King or Prince Chu). Li-Shi-Zhen was working in the department called “Good Doctor Department (良医所)”[6], and was motivated by the massive compilation and publication process going on for other medical works. He presented his idea of writing, summarizing, and compiling the medical compendium to the governor King Chu, but was turned down by the governor. He finally left his job in the medical institution and started working on Ben-Cao-Gang-Mu on his own – it took him nearly 27 years to finish editing and writing the whole book[3]. The first draft of this book was finished in 1578, but it was not published and printed after Li-Shi-Zhen’s Death, by a publisher named Hu Chenglong in Jingling, Nanjing (the formal capital of China before the third Ming emperor). There are some discrepancies in the exact year when the first version of Ben-Cao-Gang-Mu was printed: some scholars suggested that it was printed in 1593, during Li-Shi-Zhen’s last year, and the contents was proofread and verified by Li’s family [9]. Other scholars have suggested that the first version was printed in 1596[10].
Copyright and Reprint in the Qing Dynasty
The Qing Dynasty (1644-1912) is the last imperial dynasty in China, and it followed right after the Ming Dynasty. The Qing Dynasty was established by Manchu with a highly centralized government structure, and had huge social turbulence in its later years.
The original version of Ben-Cao-Gang-Mu underwent a re-organization and revision on the illustrations in 1640, right before the establishment of Qing Dynasty. It was re-recognized by people in the Qing Dynasty after this revision, and was very frequently re-printed during Qing Dynasty, having “at least 15 editions”[10]. The recorded editions of Ben-Cao-Gang-Mu during Qing Dynasty were around 1658, 1684 and 1717[10].
Interestingly, the re-print version here was published in 1657, which was just around the first edition period documented during the Qing Dynasty for Ben-Cao-Gang-Mu. This Re-print version was published by a publisher named “Jie-Zi-Yuan(芥子园)”.
The history and origin behind the Re-print publisher Jie-Zi-Yuan (芥子園)
Jie-Zi-Yuan (芥子園) is not the name of a person, instead, it is actually the name of the mansion where a famous novelist and playwright named “Li-Yu (李渔)” from the Qing Dynasty resided. Li-Yu wrote a lot of short novels, essays, and comedic works, but was also a dedicated publisher. Jie-Zi-Yuan located in Nanjing, which was the former capital of China before the third emperor of Ming Dynasty (after that, they moved the capital to Beijing, which is the capital of China today). Nanjing was the cultural center in China, where a lot of famous writers, poets and artists lived during Qing Dynasty. The publishing industry flourished in Nanjing starting from Ming Dynasty, when the first emperor of Ming (Zhu-Yuan-Zhang, known as Hong-Wu Emperor) recruited craftsmen specialized in woodcut printing to be trained and work in the publishing companies in Nanjing, leading to the development of publishing industry. [11]
Before moving to Nanjing, Li Yu’s novels, plays and literature works were pirated by publishers from other parts of China, and he was really frustrated. Attracted by Nanjing’s prosperous publishing industry with standardized publishing process and protection for copyright, he moved to Nanjing around 1657[11], established his own publishing company using the name of his mansion in Nanjing, with the help of his son-in-law Worth noting, this re-print version of Ben-Cao-Gang-Mu was published in 1657, which matched exactly with the approximate time when Li Yu moved to Nanjing. Li-Yu not only published his own work but also a lot of other famous or popular books in his own publishing company to attract customers. Since Ben-Cao-Gang-Mu was re-recognized in Qing Dynasty and was very famous, that’s probably why Li-Yu decided to re-print and publish this work.
Book Feature
Substrate
The pages of this book were made from paper. The first page of this book with publisher information was made with a different kind of paper than the rest of the pages. The paper used for this page has a cream-white color. And from the image on the right, we can clearly see the chain lines of this paper - this indicates that the paper is probably laid paper that was hand-made. This kind of paper is actually very similar to a type of paper called “Xuan paper” (宣纸), or “rice paper” in China, which is primarily used for artistic purposes such as chinese water painting and calligraphy. During Qing Dynasty, the paper-production industry expanded very rapidly[12], or rice or bamboo which were used in earlier times.
Also, if we compare the font of the text in this title page with that in rest of the book, the difference in the regularity of the font suggests that the Chinese Characters in this title page are probably hand-written using ink and soft brushes. The use of “Xuan paper” for this title page also agrees with this hypothesis because Xuan paper is mainly used for practicing Chinese Calligraphy and is suitable for hand-writing using Chinese soft Brushes. The rest of the pages in this book are made from another type of paper with a yellow and brown color.
The paper from this book is extremely fragile and crispy - when I was examining the book, I had to be very gentle when carrying the pages, otherwise the piece of the page i was carrying would immediately fall apart. The fragility of the paper is probably due to 2 reasons: 1) The book was published in 1657, which was 366 years ago, so the material probably degraded and that’s why the paper is so fragile 2) Probably it’s also because the paper is hand-made, so it lacks industrial processes or additions to strengthen it.
Format
The original Ben-Cao-Gang-Mu has 52 volumes in total, but only 47 volumes are collected by the Kislak Center at Pennand bound into 6 “books” in codex format, each containing 8 volumes. The re-print demonstrated here is the book 1 with the first 8 volumes of Jie-Zi-Yuan Reprint Ben-Cao-Gang-Mu.
The original format of Jie-Zi-Yuan Reprint Ben-Cao-Gang-Mu is probably separated as individual volumes. The numbers from “1” to “8” on each volume of the book suggests that the volumes were separated before the library binding.
Binding
The library re-binding combined each 8 volumes of the original book together into a new book with codex format. The book now has a hard cover, with information including title of the book, library identification number, language category as well as volume number recorded on the spine.
Though the library combined the volumes and bound them together in a codex format, the original binding of Jie-Zi-Yuan Reprint Ben-Cao-Gang-Mu did not follow any traditional bibliographic formats. It is an example of a traditional Chinese binding which combines “thread binding” and “Wrapped back binding” which originated from “butterfly binding”. “Butterfly binding” was developed in Tang dynasty (618 to 907) and became popular in Song dynasty (960 to 1279). In butterfly binding, each printed sheet of paper was folded in half. The printed pages faced directly to each other, and these sheets were pasted together to form a book[13].At the first glance, the volumes of this Jie-Zi-Yuan Reprint Ben-Cao-Gang-Mu, seem to be bound by butterfly binding, but the folded edge of the sheet of the paper is facing outward – this suggested that it is bound most likely by wrapped-back binding. Wrapped-back binding was widely used in the Ming Dynasty, and it originated from butterfly binding. The only different in wrapped-back binding is that the folding of the sheet of paper is reversed compared to butterfly binding, so the printed pages are on the outside, with the edges of paper facing inside and being bound together. Most importantly, with wrapped-back binding, the fold on the sheet is now at the fore-edge of the book[13]– this corresponds to what we’ve seen on the fore-edge of this book. Normally books with “butterfly” or “wrapped-back” binding paste the pages together, but this book also applies “thread binding”, in which pages are sewn together with threads instead of being pasted together. Thread binding is used to prevent insect harm to the paste[13]. From this picture we can clearly see traces of white threads used to sew the sheets together.
Book Use
The wrapped-back binding of this book helps navigate the readers when they are reading it. The area that is folded on each sheet of paper contains information about chapter title, chapter number, and volume number (in order, from top to down). Unlike butterfly-binding where the fold is inside, in wrapped-back binding, the fold on the sheet now faces outwards and is at the fore-edge of the book. This really helps the reader to better navigate the content of a long catalogue book, knowing which chapter and volume they are at while reading. Also, it helps the readers to find desired information much more quickly, as they can easily navigate to the content they are looking for using the information on the fore-edge fold.
Vertical Margins
Another element from this book object that might help the readers to navigate the content is the vertical line (or the vertical margin) on each page. These vertical margins are very similar to the margins that appeared on the letter practicing books, and they help organize the texts into a clearer structure. These vertical margins separate the texts into distinct columns, and help prevent the texts from overlapping with each other - this feature helps the readers to navigate the contents better as they will have a better sense of the flow of the content. Also, the vertical margins suggest that the texts are meant to be read from top to down, which navigates the reader to read in this order.
The right-most vertical margin on the page is much thicker than the other lines in between the texts, which suggests that the contents start from here, on the right side of the page, and navigates the readers to read from right-to-left, in a top-to-down order.
This mechanism informs us about the different expectations readers have in terms of the order in which they should read the text - different readers under different cultures may have different expectations towards the way in which the texts are ordered. In most Western books, the texts are written and meant to be read horizontally, from left to right, but in books from East Asia, in this case, China, the texts were often written and read from right to left and organized in vertical columns. This mechanism tells us that probably the readers are assumed and expected to be comfortable with reading from top to down, right to left - but if the readers are coming from a culture in which the texts are organized in horizontal order, these vertical columns and margins will help them re-orient the way they read the texts and navigate them through the whole book.
Repetitive Notation marking start and end of each chapter and volume
Another element this book has which helps navigate the readers is the repetitive notations marking the beginning, end and the location of the content with respect to the whole volume. These notations are consistent in the meaning they represent thoughout the whole book, and are being used repetitively in every volume. Common examples for these notations are: 上 (first half of content), 下 (last half of content), 序 (beginning), and 终 (end). These notations helps the readers to navigate different contents from the different chapters and volumes of this book. This mechanism tells us that probably the readers are expecting that different volumes of the book will discuss different contents and aspects of Chinese herbal medicine, so all these notations will navigate them and inform them about where they are in the book.
| Notation | Example | Meaning |
|---|---|---|
| "上" (shang) |  |
meaning “up” in English, is used to mark the first half of contents in the same volume. Here is the example picture of a start page from volume one, with “上” informs the reader that this is the first half of the content from first volume. |
| “下” (xia) |  |
meaning “down” in English, marks the “last half” of contents in the same volumeIn the example picture from the first volume, the page with “下” reminds the reader that now they are in the last half of the content from the first volume. |
| “序” (xu) |  |
means beginning and marks the start of a chapter or a volume. |
| “终” (zhong) |  |
means “end”, and marks the end of a chapter or a volume. |
Annotations
There are number annotations in the margin area for the graphic sections of this book - surprisingly, the numbers annotated align well with the actual total number of graphs in each page, which suggests that probably one of the readers order all the graphs by assigning individual numbers to every one of them. These number annotations tell us that the graphic section of this book is probably read in the order by which the graphs appeared on each page. The readers do not jump between different pages and different graphs - instead, they view the graphs in an anti-clockwise order on each page, and followed page by page. I do not have a clear answer on by whom these annotations were written, as I do not see any names on the pages. But these number annotations were written in pencil, so probably they were annotated by a more modern reader (probably not until 1900s when pencils became a popular writing tool).
Book Circulation History
The former owner of Jie-Zi-Yuan Reprint Ben-Cao-Gang-Mu (芥子園重訂本草綱目) was McCartee Divie Bethune (1802-1900). He was born in Philadelphia, and was a Protestant Christian medical missionary[14], and also the U.S. diplomat to China. He travelled to China in 1843, opened mission and organized Protestant Church, and also worked as an interpreter as well as a temporary American Consul in China before his return to the U.S. around 1880s [15]. The time when McCartee travelled to China was during late Qing Dynasty, right after the first opium war (from 1839 to 1842). During these years, there were huge transformations in regime and social structure and the social environment was highly turbulent. Since McCartee was a medical missionary, he probably collected this book during his medical work and research when he was in China as Ben-Cao-Gang-Mu was one of the most important books in Traditional Chinese Medicine History.
McCartee donated Jie-Zi-Yuan Reprint Ben-Cao-Gang-Mu (芥子園重訂本草綱目) to Penn, and after that, the book was circulated among different Penn Libraries until today, as evidenced by different bookplates and library stamps on the page. The exact time when McCartee donated the book to Penn was unknown, but it was most probably around late 19th century and early 20th century. The bookplate from McCARTEE library was probably the oldest bookplates among all the ones. This bookplate appears on the first page of every single volume of this book, which suggests that Penn Library first collected this book in separate volumes. The library was name after McCartee because he donated a lot of books to Penn, and was probably around late 19th century. The other bookplate and the book-stamp were probably from mid 1900s. The bookplate with “University of Pennsylvania, rare book and manuscript library” is the most up-to-date one and is probably from the 21st century when the kislak center for special collections, rare books and manuscripts was built.
Evidence of Readership
Interestingly, this book was first placed in regular shelves when Penn Library first collected it. The borrowing card, showing that somebody borrowed it in 1970 and 1974, shows evidence of readership back in 1900s. This borrowing card suggests that book is still on the regular shelf where people can take and read it freely in the 1970s – probably the book had more readers back in the 1900s when it was still on the regular shelf than today. The bookplate from Kislak suggested that this book was probably not identified as rare book and protected until the 21st century. After it was collected by Kislak center, the book is identified as a rare book and finally being properly protected.
