Avicenna is said to have written more than 100 books, most of which have perished. He wrote on the etiology of epilepsy and described diabetes, noticing the sweetish taste of the urine. His Canon is one of the most famous medical texts ever written; a complete exposition of Galenism. Neuburger says: “It stands for the epitome of all precedent development, the final codification of all Graeco-Arabic medicine”. It dominated the medical schools of Europe and Asia for five centuries. The above is a Latin translation by Gerard of Cremona.  ISTC no. ia01417500.  ISTC no.  ia01417700 describes another printing of the same translation issued in Strassburg by Adolf Rusch (the R printer), also in 1473.
