* * *Not many books remained popular and in great demand for over a millennium, and also repeatedly translated into many languages for institutions of higher education. One such manuscript was written at the end of 9th century CE by a brilliant polymath, Abu Bakr Muhammad ibn Zakariya al-Razi (865- ca. 925) or Rhazes (in Latin) who contributed to medicine, philosophy, mathematics and music. To quote F. H. Garrison, "Rhazes, a great clinician, ranks with Hippocrates, Areteaus and Sydenham" . His treatise on smallpox and measles was the first authentic account of this disease, remaining in print till the middle of the 19th century.

The earliest epidemics of smallpox have been reported from the banks of the Nile, from where it spread to the Middle East, Europe and Asia. Since then, smallpox has devastated populations until its eradication in 1977. Surprisingly, despite the havoc it caused, very little was recorded in medical literature and it is absent in medical papyri . The plague of Athens of 430 BCE is said to have been due to smallpox but Greek medical texts do not discuss it as a disease, thus Galen made only passing mention to smallpox, nor was it discussed by the Chinese. Three Indian medical texts contain only minimal and identical descriptions of a condition Masurica (when pustules like brown lentils appear), translated as Variola, that is smallpox . Similar interpretations are made by better informed historians . Some are of the view that Masurika was not smallpox but chickenpox and that early Indian medical texts did not describe smallpox as it was not prevalent in India till 12th century CE. However, this is unacceptable for everywhere else smallpox and chickenpox existed side by side; moreover, trade links existed via the Silk Road and sea routes with India and Egypt, Mesopotamia, Greece, the Roman Empire and China where smallpox was endemic. With huge movements of human and animals taking place for thousands of years, it is against logic that India remained free of this highly contagious disease.

Smallpox was first documented in a Syriac medical text by Ahrun of Alexandria in 622 CE, but Rhazes wrote the first comprehensive text, its translations remaining in print till the middle of the 19th century. The Arabic title of the book is Kitab fi al-Jadari wa-‘l-Hasaba, translated into Latin as Variolis et Morbillis and into English as A Treatise on Smallpox and Measles. In his introduction Rhazes stated when meeting other medical men, a discussion on smallpox took place and, after he had explained his views, he was asked to write a full description. He noted that Galen only mentioned smallpox briefly and referred to the Arabic translator of the Syriac of Ahrun of Alexandria without mentioning the book itself. In one chapter, he differentiated smallpox from measles and also observed that survivors of smallpox never suffer again.

The book was edited in Arabic: Kitab fi al-jadari wa al-hasaba li-Abi Bakr Muhammad Zakariya al-Razi. Printed at the expense of the Syrian Evangelical College of the city of Beirut, 1872. (Source).
Although the book was translated into numerous languages and copies of these are found in collections and libraries, there are only two original Arabic manuscripts. One is in the Leiden University Library (Fig. 1) and the other in the National Library in Venice, both being donated nearly 400 years ago . That in Leiden has been used by translators and researchers but the other in Venice has not seen the light of day for centuries. Rhazes's book remained in great demand until about the middle of the 19th century, being the only book available on smallpox. It was first translated into Greek and subsequently nearly 40 times into almost every European language. It was first translated into English from a Greek text by Mead in 1747 and published in London, followed by two more translations in 1756 and 1762 with reprints in Edinburgh. London and Dublin. A popular translation by the famous London Apothecary John Channing (died 1780) was published in 1766. This was a Latin translation with the Arabic on opposite pages (fig. 3-4). The last English translation by Greenhill in 1848 is said to be the best; because it was translated direct from the rare original Arabic manuscript borrowed from the Leiden University Library ; it was last reprinted in 1875. An Arabic version was published in 1872 in Beirut.

Lady Mary Wortley Montagu and the Introduction of Smallpox Vaccination to England by: Dr. Salim Ayduz
This short article describes Lady Montagu's efforts in introducing a technique of vaccinating against smallpox; a technique that she learnt from Ottoman Turkey and transported, against some resistance, to the shores of Britain. It was from this knowledge, which had existed for some time in the Muslim lands, that Dr. Edward Jenner was able to develop modern methods of smallpox vaccination.
Al-Razi on Smallpox and Measles by: Abdul Nasser Kaadan, MD, PhD
This article by Dr. Abdulnasser Kaadan shows that as early as the 9th century, the well known Muslim physician al-Razi described, in his book Kitab al-Jadari wa 'l-Hasba (The Book on Smallpox and Measles), the symptoms of smallpox and measles. Furthermore, he distinguished between the two diseases, using an antecedent of the modern differential diagnosis.

Lady Montagu and the Introduction of Smallpox Inoculation to England by: FSTC Research Team
FSTC Research TeamThe English aristocrat and writer Lady Mary Wortley Montagu (1689-1762) is today remembered particularly for her letters from Turkey, an early example of a secular work by a Western woman about the Muslim Orient. When Lady Mary was in the Ottoman Empire, she discovered the local practice of variolation, the inoculation against smallpox. Unlike Jenner's later vaccination, which used cowpox, variolation used a small measure of smallpox itself. Lady Mary, who had suffered from the disease, encouraged her own children to be inoculated while in Turkey. On her return to London, she enthusiastically promoted the procedure, but encountered a great deal of resistance. However, her example certainly popularized the practice of inoculation with smallpox in British high society. The numbers inoculated remained small, and medical effort throughout the 18th century was concentrated on reducing the risks and side-effects of the inoculation process.
Caesarean Section in Early Islamic Literature by: Dr. Nasim Hasan Naqvi
Dr. Nasim Hasan Naqvi
Some medical historians of the last century mistakenly recorded that Caesarean section was strictly forbidden amongst Muslims. This opinion has been repeatedly quoted without examining its authenticity or validity. Research into available ancient Arabic sources can lead to evidence contrary to such a view. The Islamic scholars of the Middle ages were, in fact, the first to not only write about this operation but to illustrate it in pictures and describe it in poetry. Considering the antiquity of their time, it is unfair to compare them with scholars of a later date; but their achievements must be valued.
