The present volume contains the Syriac text and English translation for three separate works. The first is a letter from Jacob of Edessa to George of Serug on the topic of Syriac orthography. The second is a treatise also by Jacob Edessa that deals with issues of Syriac grammar such as person, tense, pronunciation, and so on. The third and final text is a treatise on Syriac accents written by the thirteenth century polymath Gregory Bar Hebraeus. The texts are edited and translated by George Philllips, and Philippis supplements the translations with an annotated apparatus.
