The New Iadgari is a significant Georgian hymnographic collection from the 9th–10th centuries, encompassing hymns for the liturgical year. Despite its importance, its Georgian sources remain underexplored. Recent discoveries, such as the Greek manuscript Sinai MG NF 56+5 and the Syriac version in Sinai MS Syriac 4, provide valuable insights into the text's transmission and evolution.
A unique feature of the Georgian New Iadgari is the commemoration of the “Burnt Fathers” on March 19. This narrative, absent in the Greek and Syriac versions, recounts the martyrdom of ascetic monks attacked and burned by their enemies. The liturgical structure includes stichera on "Lord, I have cried," a mattins canon, and stichera on Lauds, emphasizing themes of faith and sacrifice.
The New Iadgari highlights Georgian contributions to Eastern Christian hymnography and reflects the dynamic adaptation of liturgical texts across linguistic and cultural boundaries.
