 The Syriac Christians adopted a teaching tradition which included a truncated version of the Alexandrian Organon (Porphyry's Eisagoge followed by the Categories, On Interpretation, and the first seven chapters of the Prior Analytics). This teaching tradition continued without disruption through the Arab conquests and under the Umayyad Caliphate (661–750). During this period, however, it evoked little if any interest on the part of the Muslim conquerors.
