This Festschrift honours Dr. Gerrit Reinink on the occasion of the end of his professional career as a senior lecturer of Syriac and Aramaic studies at the University of Groningen, The Netherlands. The Festschrift includes, in addition to a brief biography and a complete bibliography of Reinink's scholarly writings, fifteen articles, arranged according to the chronology of their topics and covering a wide variety of subjects, ranging from the days of Julian the Apostate to the year of the fall of Constantinople, through the period of Late Antiquity, the Byzantine period, early Islam and the Middle Ages. The authors are all prominent experts in the field of Syriac studies and adjacent areas. The title of the book, Syriac Polemics, is a clear reference to one of Reinink's favourite research topics: Eastern Christian reactions to the rise of Islam. This volume is a valuable contribution to the study of Syriac literature and culture in general.
