ABSTRACT
The information on Eudemus of Rhodes that can be recovered in Arabic sources falls into three categories. There is a full collection of sayings, some incidental biographical notices that mainly state his relation to Aristotle and Theophrastus, and a number of references to his views on logic which he held in common with Theophrastus. Certain considerations limit the parameters within which the answer is to be sought. In the first place, the section on Eudemus in the Siwan is so located as to make it certain beyond a reasonable doubt that the source was a Greek gnomologium. Certain considerations limit the parameters within which the answer is to be sought. Second, since Eudemus was almost completely unknown in Arabic, as already mentioned, there would have been no incentive to attribute to him forged sayings or sayings by others.
