Al-Jurjani originally composed his work Al-Zubda fi al-tibb (The Quintessence of Medicine) in Arabic, unlike his most celebrated work Al-Dhakhira al-Khwarazmshahiya (see lot 177). It is divided in two parts: a first section on theoretical medicine and a second section on the treatments of ailments. Al-Zubda fi al-tibb is famous for giving a classification of drugs into three categories: mineral, herbal and animal. Only a few copy of this work appear to be preserved, one of which is the United States National Library of Medicine (http://www.nlm.nih.gov/hmd/arabic/E14_E16.html). For a further discussion on Al-Jurjani's works please see lot 177
The Taqwim al-Sihha [bi al-asbab al-sitta] (The Almanac of Health) by Ibn al-Butlan is his most famous work and one of the most celebrated works on the rules of good health and hygiene. The Taqwim al-sihha gives the principles of medicine using numerous tables and precise examples, however with a particular interest for questions related to nutrition. Another copy of this work, dated 1213 AD, is in the British Library (À l'ombre d'Avicenne, La médecine au temps des califes, exhibition catalogue, Paris, 1996, p.236). The 13th century Latin translation of the work, titled Tacuinum sanitatis, knew great popularity in Europe.
