The present critical edition of the Martyrdom of Cyriacus and Julitta is based on the MS of the Vаtican Library, Syriac 161 (its facsimile reproduction was issued by the Bibliotheca Apostolica Vаticana together with Brighаm Young University) and on the text of the Martyrdom edited by P. Bedjan (Acta Martyrum et Sanctorum III). The latter was collated with the relevant part of the MS of the Institute of Oriental Manuscripts, Saint-Petersburg (Diettrich d). The edition is accompanied by a thorough philological analysis of the text. The target audience of the edition are scholars specialized in the Syriac literature (in particular, Syriac hagiography and apocrypha) as well as those interested in studying Syriac language and textual criticism.
Yōḥannān Bar Zō‘bī was an East-Syriac author of the late 12 th–early 13th c. His Explanation of the Mysteries is a metrical commentary on the liturgy. It is preceded by a prologue narrating the biblical history from the beginning of creation to the redemptive mission of Christ, and followed by a doctrinal part as well as a conclusion that describes symbolism of the church. The poem is presented in a critical edition which is based on nine manuscripts, including the oldest known one.
