Anatomy is a discipline which needs to know human body very well. However, even the earlier times human being certain coincidence to learn it by die means of some accidents and fights in order to obtain dieir nutrition. We learn it through the wall pictures which were drawn by the human of d٦at period of time. After then, certain people were interested in human anatomy in order to treat people. It means that anatomy became a fundamental branch of medicine, although, they did not make human dissection which was the method of anatomy. In Corpus Hippocraticum there is limited anatomical knowledge.
When we talk about classical anatomical knowledge, generally we mean Hippocratic and Galenic anatomy. Galen wrote a book named De Usu Partium and some odier works. In those works he explained the human anatomy and die function of the systems, depending on mainly animal anatomy He made dissection on certain animals as pigs, apes etc. and accepted that human body resembled their structures. For instance, his explanation on muscles shows diat he took the anatomical structures of muscles of human being from apes, as is seen die explanations of die muscles of the extremities.
As is known that in Islam in earlier period of time, nearly all of the classical medical works were translated from Greek and Latin into Arabic and the scientists who lived in the World of Islam had opportunity to learn earlier anatomical knowledge through them. Among diem can be mentioned Rliazes (IX.cent.), Ali b. Abbas (Haly Abbas) (X. cent.) and Avicenna. In general when they prepared their works they depended on those classical works, especially Hippocrate's and Galen's.
Avicenna (980-1037) was the famous physician who lived in Islamic World in the eleventh century. He was interested in physics, chemistry, astronomy, matfiematics, music and philosophy, but he became famous because of his studies on medicine. He wrote many books on this subject, Among them can be mentioned Kitab al Adviya al Kalbiyye, Risala fi al-Hindiba, al- Kanun al-Sagii etc. However they were merely brief risalas on certain branches of medicine. But his famous work, Qanun was different from the rest of his work. It was a kind of medical encyclopaedia which consisted of 5 books.
Avicenna had great influence on the following medical studies and especially by the means of the last famous work. It was translated to Latin in the thirteenth century by Gerard of Cremona and its Latin version was published in 1527 and 1544. Its Arabic text was also published several times until the end of the seventeenth century in the West. For that reason, it created enormous extensive influence on the early Western medical studies.
It had not only influence on the Western medical men but also on the physicians in the Ottoman Empire. His work, Qanun was accepted as a handbook of medical sciences and it was on the curriculum in the medical madrasas until nearly the end of the first half of the nineteenth century in East. For, after the new medical school was founded in 1827, the medical madrasas continued their activities in the following years and it was on the curriculum.
Avicenna's famous work, Qanun contained information about all of the medical subjects. In the first book there are information about die theory of humours, anatomy, pathology (very briefly) and public health. Avicenna explained whole structures of human body classifying them in systems as skeleton, muscles, etc. as is seen in modern books of anatomy, nowadays. There is an explanation abont the functions of organs which can be named as phy- siology, nowadays.
The second book is on the simple drugs. He gave information about the usage of tlie simple drugs and the preparation of the drugs for what kinds of diseases they could be used.
The third volume is about pathology. He explained the diseases of whole liuman body, beginning from the head to the feet. He gave symptoms and prognosis of the diseases.
Surgery and contagious diseases are explained in the fourth book. Avicenna also gave explanation about the contagious diseases in this book. Complex drtrgs treated in the Akrabadin', fifth book.
Avicenna had great influence on die Western and Eastern medical Stu- dies; especially al-Qanun was very effective on their studies. One of them was Itaqi who lived in the Ottoman Empire in the seventeenth century. His book was named Tasrih al-Abdan ve Tarceman al Kibale-¡ Faylasufari.
Tashrih al- Ebdan is the only illustrated monograph on anatomy written in the Ottoman Empire. Some historians of medicine claimed that tliis work was simply translation of Ahmed b. Mansur's Teshlih al Abdan which was written in the fourteenth century. Mansurs work is also an illustrated mo- nograph on human anatomy, but it is shorter-. Itaqi's work explains the sub- jects in detail. It is about 276 pages: Ibn Mansur' work is merely 25 pages. Itaqi used this work and its anatomical illustrations, but he also put some ot- her illustrations which were taken from Vesalius' Fabrica (1543). Tashrih al- Abdan also contains some other illusuations which cotrld be drawn by Itaqi, himself.
Shems al-Din Itaqi lived itr Shitvan until 1604. In those days there was a war between the Ottoman Empire and Iran. As a result of this Itaqi lost Iris family and some of nearest friends, and he had to live Iris motherland. He came to Istanbul. In there Grand vizier, Recep Pasha helped him. Itaqi wrote the book, mentioned above, in order to thank the Sultan Murad Han IVth and Recep Pasha. He said that when he prepared his book he used Avicenna's famous work, al- Qanlln and Rhazes al-Havi (Continens) and Bagdadi's works.
The plan of Itaqi's work is nearly same as the first book of al-Qanun. However, it is typical plan of any book of anatomy, for even nowadays. Itaqi, also began his book with explaining the 4 elements and 4 humours, and then he gave the characteristics of each organs. However, he separated the organs into two main groups; simple organs and complex organs. This classification is found in Avicenna. He also classified the organs into two main groups and also said that simple organs were the organs which consisted of the same structure, as blood, bone and muscle etc. but complex organs were different, like the system of respiration and digestive system. From this explanation we think that Avicenna and Itaqi described each simple organ as a kind of tissue.
In general, aldiough Avicenna excepted Galenic anatomy and explained die organs depending on it, time to time, his explanations are different from his; for instance, his explanation of the bones of the extremities are quite different from Galenic anatomical knowledge. His explanation about the division of the vessels of upper extremities are also different from the Galenic explanation. We can increase the examples on this matter. However, depending on such information, some physicians claimed that Avicenna should have been made dissection, although he had never mentioned it.
When we look at the Itaqi's book, we can define certain resemblance between Avicenna's and Itaqi's explanations. However, Itaqi also gave certain information which are quite different from Avicenna's information in some points. However, the resemblance between Itaqi's work and Avicenna's al- Qanun is natural. For, Itaqi have known the earlier anatomical knowledge very well as a physician. But he made certain contribution and in some point he did not accept neither Galenic anatomy nor Avicenna's. One of them can be defined in the explanations of the nerves. For instance, Galen said that
there were 7 cranial nerves, and the first cranial nerves were optic nerves. Although A١٦cenna accepted his classification, he mentioned olfactory nerves but he did not add it into the classification of the cranial nerves. Itaqi added this pair of nerves into his cranial nerves classification as the first pair of cranial nerves. In addition to them, Itaqi also gave different knowledge about the function of the third, fourth and fifth cranial nerves from Avicenna’s.
Iraqi's explanation about the embryo is also different from Avicenna's. Here Itaqi preferred to give information comparing different physicians’ opinion and one of them was Avicenna's.
As is known that Ibn Nafis (13.cent.) discovered the lesser circulation and we know that Itaqi knew well his famous book, Sharh-i Tashrih 1'Ibn Sina. This book is a commentary written on die anatomical part of al-Qanun. Ibn Nafis explained the lesser circulation in the five different places of this book. Although Itaqi mentioned Ibn Nafis among the physicians whom he used their books when prepared his work, he did not realise the difference between the other physicians' and Ibn Nafis' explanations. For that reason, he still gave classical information about the lesser circulation.
Itaqi was the first physician in the Ottoman Empire who showed Western influence very clearly. Although he used classical books of anatomy, and Avicenna’s al-Qanun was the most important of diem, he used Vesalius famous book, Fabrica (1543) which was accepted the first book of modern anatomy in which Andreas Vesalius showed that dissection should have been used as a research method of anatomy. Itaqi did not only copy some of the illustrations of this book, but also used its explanation as well. One of the clues which shows us that he used Fabrica, is die explanation of the functions of the muscles of the neck.
As a conclusion we can say diat Itaqi used Eastern and Western sources very well, but for him, Avicenna had quite different place among them.
Itaqi also used Ahmed b. Mansur's book’s illustrations in addition to Fabrica, Vesalius' book. We can have chance to compare the two different kinds of illustrations. Ahmed b. Mansur's work had no perspective, contrary to Fabrica.
But I should said that Itaqi also gave some illustrations or in better word, some schemata which were probably drawn by himself; these schemata are suitable the explanations in his text. Some of the samples are seen in the explanation of the cranial nerves.
