Aim of this study was to determine whether Vesalius and Valverde influenced Shams al-Dīn ʿItāqī considering the figures and several statements in Tashrīḥ al-Abdān wa Tarjamān Qibāla Faylasūfān. The statements and figures in illustrated copies of ʿItāqī’s book were examined and compared to those in Galen’s, Avicenna’s, Vesalius’s, and Valverde’s works, then the findings were evaluated. ʿItāqī’s book contains some figures only from Vesalius and/or Valverde’s works, but there is no new explanation related to issues such as the mandible, the sacrum, the rete mirabile, and the uterus. The Latin edition of Valverde’s book published in 1607 was probably the source of the Western-originated illustrations in the manuscript Hüsrev Paşa, Nr. 464 and of all the Western-based illustrations, except for the female figure in the manuscript of Istanbul University, Turkish Manuscripts, TY 2662. Spanish and/or Italian and/or Latin (1589) editions of Valverde’s book were the sources of most of the Western-originated illustrations, except the human skeleton figure in the manuscript of Prof. Uzluk’s personal collection. The information given by the works of Vesalius and Valverde has not influenced the explanations of ʿItāqī. ʿItāqī wrote his book according to the classical anatomical knowledge in the Islamic world of his era and he added Eastern- and Western-originated figures to his book to support/strengthen his statements. Or ʿItāqī work Tasrīḥ al-Abdān originally contained no illustrations. However, later, scribes/copiers added Eastern- and Western-originated anatomical figures to the book to support/strengthen statements at different times.

Anatomy was an important subject to solve human health problem. In Islam Avicenna (980-1037) was well known physician and he was also interested in anatomy and gave description on this subject in detail in his famous work, al-Qanun. Avicenna showed extensive influence on the physicians lived in the following the centuries, not only in the eastern countries, but also in the West. His work, al-Qanun was translated into different languages including in Latin. Its Latin version was published several times in different countries in Europe. Avicenna was also very influential in the Ottoman Empire. His work, al-Qanun was used extensively as a handbook among the physicians. One of the physicians who showed this influence obviously was Shams al-Din Itaqi in the Ottoman Empire in the seventeenth century. He wrote an illustrated anatomical work, named 'Treatise on Anatomy of Human Body'. 'Treatise on Anatomy of Human Body' was written in Turkish and gave description of the anatomical structures of the whole human body in detail including in several anatomical illustrations of some of the organs in colour. When we study Itaqi's work we can define the resemblance of his anatomical explanations witlı Avicenna did in his al-Qanun, as is seen in the classification of the organs as simple and compound organs. Itaqi also gave original description of some of the organs in his work. Among them can be mentioned the description of the cranial nerves.
