Abstract Daniel King’s book The Earliest Syriac Translation of Aristotle’s Categories may be considered the first critical edition of a Syriac translation of Aristotle’s works. Thus, it raises a number of questions of textual criticism that may be discussed against the background of D. Gutas’ research in the field of Graeco-Arabic studies. This article provides a critical review of the book and a description of the new online publication of the anonymous Syriac translation of Aristotle’s Categories in the HUNAYNNET database.
