The Society of Oriental Liturgy (SOL) is an international academic society dedicated to the scholarly study of the various Eastern Christian liturgical traditions and related fields in all its aspects and phases, including allied disciplines, and its multiple methodologies.

This volume brings together a selection of contributions from society members that germinated from papers delivered at the SOL congress gathered in Etchmiadzin, Armenia in September 2016. The chapters reveal new and original research on a variety of topics pertaining to Eastern liturgical rites, including, inter alia, methodological reflections on the field of liturgiology, analysis of unedited Syriac and Ge'ez liturgical texts, investigations on the development of the liturgical calendar in late antiquity, a study of medieval Byzantine hymnography, and a discussion of liturgical renewal for the Armenian Apostolic Church. These and the many other original topics explored herein show the dynamism that characterizes the study of Eastern liturgy today while also calling attention to the many questions that have yet to be explored.
