Hunayn Ibn Ishaq Al-‘Ibadi, Abu Zayd
HUNAYN IBN ISHāQ AL-‘IBāDī, ABū ZAYD
known in the Latin west as Johannitus (b. near Hīra, Iraq, 808;d. Baghdad, Iraq, 873)
medicine, philosophy, theology, translation of Greek scientific works.
Huanyn, a physician, philosopher, and theologian, was the most famous ninth-century translator of works from Greek antiquity into Arabic and Syrinac. His nisba al-͑Ibādī, is from an Arab tribe, al-͑Ibād, the members of which became Christian long before the rise of Islam and continued to belong to the Syrian Nestorian church. His father, Ishāq, was a phramatic (saydalāanī)at Hīra. While still young, Hunayn learned Arabic and Syriac, perfecting his knowledge of the former at Basra. Ibn Juljul incorrectly reports that in Basra, Hunayn met Khalil ibn Ahmed, founder of Arabic grammar; M.Plessner has shown, on chronological grounds, that this would have been impossible1.
Hunayn went to Baghdad to study medicine- a dificult undertaking, according to the picturesque and lively account given by Ibn Abī Usaybi͗a in his ͑Uyūn al-anbā͗. The teaching of medicine was then dominated by Yūhannā ibn Māssawayh, originally from jundīshāpūr. The physicians of that city, highly cultivated men who had long devoted themselves to medicine felt contempt for the people of Hīra, who were concerned primarily with commerce and banking. Further, they were not happy to see these merchants’ sons becoming interested in medicine.
Nevertheless. Ibn Māsawayh agreed to supervise Hunayn’s studies and gave him a book on the various medical schools. Avis for knowledge, Hunayn never tried of raising questions (sāhibsu’āl): one day, when they became particularly urgent and difficult to answer, Ibn Māsawayh flew into a rage and brusquely rebuked his young student:
What makes, the people of Hīra want to study medicine? Go away and find of your friends: he will lend you fifty dirhems. Buy some little baskets for a die hem, some arsenic for three dirhems, and with the rest buy coins of Kūfa and of Qādisiyya. Coat the money of Qādisyya with arsenic and put it in the baskets and stand by the side of the road crying: “Here is true money, good for giving alms and for spending …” Sell the coins; that will earn you much more than the science of medicine2.
He then ordered Hunayn to leave his house.
Refusing to accept defeat, Hunayn resolved to pursue his vacation as a physician. He disappeared from Baghdad for several years, during which time he made a profound study of Greek, either in Alexandria or in the “bilād al-Rūm”, probably in Byzantium. He was remarkably successful in learning the language; Ibn Abī Usaybi͑a recounts in detail that one evening, while visiting friends, Hunayn recited verses from Homer. He also translated a work by Galen for Jibrā͗īl ibn Bukhtīshūʿ Ibn Masawayth, who had sent him away, was forced to recognize his abilities. He was reconciled with Hunayn and accepted him as a dispel: the two became close collaborators.
Following the decision of al- Ma͗mūn (d.833) to have translated made of the works of Aristotle and of other classical authors, a cultural mission was sent to Byzantium to obtain manuscripts. Hunayn, who, according Ibn Abī Usaybi ͑a, poseesed the best knowledge of Greek of anyone of his time, probably was a member of this mission. The rich lords followed the caliph’s example and soon were completing to acquire manuscripts and have them translated.
Hunayn, his son Ishāq, his nephew Hubaysh ibn al-Hassan al-A ͑sam, and another dispel. ͑Īsā ibn Uahyā, earned particular distinction as translators. Alone or in collaboration, Hunayn translated works of P,lato and Aristotle, adn of their commentators. Even more important were his translations of the major portion of the three founders of Greek medicine, whose ideas were also central to the development of Arab medicine: Hippocrates, Galen, and Dioscorides.
Hunayn’s translation methods were excellent and generally correspond to the standards of modern phi logy. severe in his judgement of poor translations made by other writers, he had even more exacting standards for his own work. Referring to his translations of De sectis, he wrote:
I translated it when I was a young man… from a very defective Greek manuscript. Later, when I was fourty-six years old, my pupil Hubasish asked me to correct it after having collected a certain number of Greek manuscripts. thereupon I collated these so as to manuscript with the Syrisc text and corrected thus in all my translation work3.
Hunayn made long journeys in order to find manuscripts, such as that of Galen’ De demonstration : “I sought for it earnestly and travelled in search of it in the lands of Mesopotamia, Syria, Palestine and Egypt, until I reached Alexandria, but I was not able to find anything, except about half of it at Damascus4” .
Hunayn and his disciples strove to render the Greek text as clearly as possible. In fact, Hunayn may be considered one of the creators of the philosophical and scientific idiom of classical Arabic. In his study of Hunayn and his school, G. Bergstrasser emphasizes the superiority of Hunayn’s versions: “The correctness is greater; nevertheless one is left with the impression that this is not the result of anxious effort, but of a free and sure mastery of the language. This is seen in the easier adaptation to the Greek original and the striking exactness of expression obtained without verbosity. It is all this that constitutes the famous fasāha (eloquence) of Hunain.”5
Hunayn soon became famous and participated in the scholarly meetings at which physicians and philosophers discussed difficult problems in the presence of Caliph al-Wāthiq (d. 847). Al-Mutawak-kil (d.861) named him head physician–thereby dismissing the Bukhtīshū͑ famlily from this post–after having assured himself of Hunayn’s absolute loyalty. He asked Hunayn to prepare a poison to be used in eliminating a supposed enemy, encouraging him with both promises of rewards and with threats; Hunayn refused. His intense scientific activity and his favor with the caliph gave rise to jealousy among his colleagues and even among his friends and students. Bukhtīshū͑ ibn Jibrā͗ in particular, sought to turn al-Mutawakkil against him, explOiting Hunayn’s iconoclastic views to this end. He induced Hunayn to spit on an icon in the presence of the caliph, who thereupon dismissed Hunayn from his post, confiscated his library, and had him imprisoned. The catholicos The odosius trated Hunayn with equal severity, excommunicating him and dismissing him from his functions as deacon. But six months later the caliph fell ill and had to recall Hunayn from prison. He again granted him favors, and Bukhtīshū͑ was exlied.6
Hunayn retained his post until his death. Although his two sons, Although his two sons, Dā͗ūd and Ishāq, both became physicians, only Ishāq followed in his father’s footsteps, devoting his efforts primarily to the translation of Greek philosophical works.
Hunayn’s immense scientific activity consisted mainly of producing translations or revisions of earlier translations (into Arabic or Syriac) but also included a number of original works. Of the several ancient lists of these writings, the most extensive is that in Ibn Abī Usaybi͑a, ͑Uyūn al-anbā͗7. G. Furlani analyzed this list and attempted to draw up a classification scheme.8 The list in the Fihrist is shorter.9 An even shorter one is that of Ibn al-Qiftī10. A compe but uncritical list of all the works was complied by Lutfi M. Sa͑di.11
For convenience, Hunayn’s works can be divided into those concerning medicine and those dealing with other subjects. Among the medical works are translations of ancient texts, summaries treatises and paraphrases of these texts, and original. For this group treaties. For this group there is a risāla sent by Hunayn to Abu͗l Hasan ͑Alī ibn yahya al-Munaj-jim in which he indicates which works of Galen he has translated12. (For this area of his activity, consult the section of this article by A. Z. Iskandar.)
The nonmedical works are varied. The nature of some has been defficult to classify with certainty as a translation, a paraphrase, or an original work, since all we have is the title. Moreover, many of these works are known only from the lists of Arabic sources.13 Here we shall present only a selection of Hunayn’s works.
On his personal life there is Kitāb ilā ͑Alī ibn Yahya, written in response to the latter’s suggestion that Hunayn become a Muslim. ͑Alī Yahyā ibn was secretary and friend of Caliph al-Mutawakkil. Hunayn also addressed his on the translated works og Galen to him. Risāla fīmā asabahu min al-mihan wal-shadāid(“Letter concerning Affictions and Calamites”) is partially quoted in ibn Abī Usaybi͑a.14 F. Rosenthal, however, contests its authenticity.
Hunayn’s writings in philosophy comprise translations (into Arabic or Syriac) and original works: translations of Plato (the Politics, the Laws, and the Timaeous); translations of Aristotle (Categories, De interpretation, Analytica priora and Analytica posteriora, De anima; fragments of the Metaphysics, and the Ethics, with Prophyry’s commentary); Kitāb fimā yuqra͗u qabl kutub Aflātūn(“What to Read Before the Books of Plato”) (“Compendium of the De caelo et mundo”); Masā͗il muqaddama li-Kitāb Furfüryus al-ma͑rūf bil-Madkhal (“Introductory Questions to the Book of Porphry Known as the Isagoge”), (“Compendium of the Commentary of the Ancient Greeks on Aristole’s Book De caelo et mundo”); (“Commentary on Aristole’s Book on Physiognomy”);15 (“Questions Extracted From the Four Books of Logic”); and a translation of the Book of Dreams of Artemidorus of Ephesus16
To this list should be added some ten philosophical texts by Galen that Hunayn translated into Syriac or Arabic, particularly That Good People May Benefit From Their Enemies, The Prime Mover Is Immobile, and What Plato Says in the Timaeus.17 In addition, Hunayn supposedly translated from the original Greek the allegorical novel upon which Ibn Sīnā was to base his Salamdn wa-Absāl.18
Works on Arabic grammar and lexicography include Kitāh fi ahkādm al-i͑rāh ͑ala madhah al-yūfināniyyīn (“The Rules of Desinential Syntax According to the Greeks”); Kitāb fil-nahw (“On Grammar”): and Kitāb al-nuqat. Hunayn’s grammar was mentioned by Elias of Nisibis in his Majālis. In the sixth majlis Elias speaks of the superiority of the Syriac language to Arabic.19 The same chapter contains a passage in which Elias mentions a book by Hunayn that is not otherwise known, entitledKitāb al-nuqat a͑nī nuqat al-kitāb (“Book of the Points, 1 Mean, Points of the Book”). As proof of the superiority of Syriac, Hunayn states that the Syrians, Greeks, and Iranians had many names for drugs (al-͑aqāqīr wal-adwiya) and instruments (ālāt) that the Arabs did not have.20
Kitāb fī masā͗ilihi al-͑arabiyya (“Book on His Arabic Questions”) is mentioned immediately after a book entitled Kitāb ftasmā͗ al-adwiya al-mufrada ͑alāhūf al-mu͑jam (“Names of Medicines Listed Alphabetically”). Hunayn may have wished to study, in a second book, the problems posed by the translations of terms for certain medicines.
Scientific subjects other than medicine were treated in the following works; Kitāb khawass al-ahidr (“On the Properties of Stones”);21Kitāb al-Jildba (“On Agriculture“): Maqāla fī͗-alwān (“On Colors”); Fi͗l-daw’ wa haqīqatih (“On Light and on Its Nature”);22Maqāla fi tawallud al-nār bayn at-hajarayn (“On the Generation of Fire Between Two Stones”); Maqāla fi͗l-sabab al-ladhī min ajlihi sārat miyāli al-bahr māliha (“The Reason That the Waters of the Sea Are Salty”): Jawdmi’ li-Kitāb Aristū fi͗l āthar al-Udwiyya (“Compendium of Meteorology”);23Maqāla fīl-madd wal-jazr (“On Ebb and Flow“); Maqāla af͑āl al-shams wal-qamar (“On the Effects of the Sun and the Moon”); and Maqāla fī qaw.s qazah (“On the Rainbow”).
Religion is the subject of Maqāla fī khalq al-insfān we annahu min maslaliatihi wal-tafaddul ͑alaylu an tcila muhtfājan (“On the Creation of Man and that it Is in His Interest and That It Is a Grace for Him to Have Been Created Needy”) and Kitfāh fī idrfāk haqfīqat al-adyfān (“How One Grasps the Truth of Religions”). Ibn Ahfī Usaybi͑a also cites Kitāb kavfixvat idrfāk al-diyfāna (“How to Grasp Religion”),24 which may be the same book. The manuscript tradition contains the title fī kayfiyyat idrak haqiqat al-diydna (“How to Understand the Truth of Religion”). Hunayn provides the criteria that make it possible to distinguish error from truth in religious matters. The true is distinguished from the false by the reasons that one adopts at the beginning. Six reasons lead people to accept falsehood; violence, misery and affliction from which one hopes to escape, the desire for glory and honors, the insidious words of a wily man, the listener’s ignorance, and kinship between the preacher and his audience.
Four reasons lead a man to embrace the truth: miracles that surpass human power, discovering proofs of the truth of hidden things in the external and perceptible signs of religion, rational and irrefutable demonstration of the truth that one embraces, and the recognition of the authenticity of the origin of a religion by the successive phases of its development.
This treatise was preserved by Abu͑l Faraj Hibatullah, known as Ibn al-͑Assāl. L. Cheikho, who mentions Hunayn’s book, notes that the Bibliothèqtie Orientale of the University of St. Joseph in Beirut possesses two manuscripts of the book by Ibn al-͑Assāl: A, dating from the fifteenth century, and B, which is from the nineteenth century and is written in Karshuni. The treatise by Hunayn that Ibn al-͑(Assāl reproduces is at the beginning of chapter 12 of the first part (A, pp. 233-238;B, pp. 93-96).25
Other religious works are Maqāla fī dalālai al-qadar ͑ala l-tawhīd (“How Divine Predetermination Is a Proof of the Unicily of God”); Maqāla fi͗-fājāl (“On the Hour of Death”)-the theologian Abū Ishāq al-Mu͗taman ibn al-͑Assāl mentions a Kitah a-ājāl and, according to a tradition reported by Mas͑ūdī,26 an Arabic translation of the entire Old Testament based on the version in the Septuagint, which was considered one of the best in existence.
A miscellaneous work is Nawādir al-falāsifa a collection of stories, letters, and apothegms of ancient Greek philosophers to which Hunayn added his own remarks. At a later period other books were compiled from extracts taken from this collection. There are two manuscripts of the Arabic text, still unpublished, and a medieval Hebrew translation published by A. Loewenthal.27 In 1921 Karl Merkle made a thorough study of the work, in which he discussed the two manuscripts (Escorial and Munich), the title, and the authenticity of its attribution to Hunayn, which dates from the Middle Ages.28 He also examined the translations: the Hebrew (done in 1200 by the Spanish poet Jehuda ben Salomo al-Kharīzī, the translator of Harīrī), the Spanish (Libra de los biienos proxerbios), and the German version prepared by Loewenthal. In addition, Merkle established the relationships between the Ādāh al-falāsifa and the Arabic sources, unpublished as well as published. Finally, he provided a translation, with commentary, of certain passages. The book is based on a similar Byzantine anthology and contains ancient elements.29 The third part deals with the death of Alexander.30 Most of Hunayn’s translations into Syriac have been lost.31
