Several hundred authors aided him in compiling this work, which is entitled "Speculum Majus." It is arranged in three parts, one of which ("Speculum Naturale") consists of 33 books that are divided into 3740 chapters; and quite a number of the divisions are devoted to topics relating to medicine. The authors, from whose writings this medical information has been abstracted, are Hippocrates, Aristotle, Dioscorides,
