[The Problemata by Cassius Iatrosophist: problems of dating and new discoveries]

Nothing is known about Cassius Iatrophist, author of a collection of Problemata, which is medical oriented but has often affinities with the analogous texts of Pseudo-Aristoteles and Pseudo-Alexander of Aphrodisia. This is a provisory survey of the elements for a possible datation: as the surname of the author suggests a late compilation, the content of some problems has very high value and reveals surprisingly a close connection between ancient medicine and philology.
