Medieval Authors
Avicenna
A. Primary Sources
Ibn Sīnā, K. al-Shifā’, ed. Ibrahim Madkour et al., Cairo 1952-1983.
S. Van Riet, Avicenna Latinus. Edition critique de la traduction latine médiévale, Louvain and Leiden: Brill, 1968ff.
--., al-Qānūn fī ṭ-ṭibb, Cairo: Bulaq 1877; repr. Beirut 1993
M.A. Shah, The General Principles of Avicenna’s Canon of Medicine, Karachi 1966. Read a review of Shah's translation 
--., O. Cameron Gruner, A Treatise on the Canon of Medicine of Avicenna, New York 1970. Read a review of Gruner's translation through JSTOR (restricted access)
Both translations cover only the first book of the Canon. Shah's is later and unlike Gruner's it includes the section on anatomy. Gruner's is based on the Latin translation circulating in Europe, while Shah's is based principally on the Urdu, supported by the Cairo edition of the Arabic. So for readers interested in the text available to Latin scholastics, the older translation will be more useful.
