Work dossier · summary and historical context
The Calendar of Ioane Zosime is a tenth-century Georgian liturgical calendar preserved in a single palimpsest manuscript (Sinai georg. 34) copied by the monk Ioane Zosime at St. Catherine's Monastery, Sinai. Composed ca. 980–990, it lists commemorations for each month, combining Georgian and foreign saints with local Sinai traditions. The calendar was not widely adopted and remains little studied. The TITUS edition is based on the sole witness, with lacunae and illegible passages marked but not reconstructed. Its original completeness and order cannot be fully verified, and it should not be taken as normative for Georgian liturgical practice.
The calendar is a rare witness to Georgian liturgical life in the medieval Sinai, showing how a diaspora community adapted and localized the broader Eastern Christian calendar. It preserves obscure saints and local traditions not found in mainstream Georgian sources, offering insights into cross-cultural exchange and scribal practice. Its palimpsest nature and single-witness survival highlight the fragility of such texts and the importance of careful editorial treatment.
The calendar was composed ca. 980–990 at St. Catherine's Monastery on Mount Sinai, a multilingual and multi-ethnic community under the patronage of the Byzantine Empire. Ioane Zosime, a Georgian monk and scribe active in the second half of the tenth century, copied the sole surviving manuscript (Sinai georg. 34) as a palimpsest over an earlier Georgian liturgical text. The calendar reflects the liturgical needs of the Sinai Georgian community, incorporating both mainstream Eastern Christian feasts and local commemorations, including saints venerated in Palestine and Sinai. Its limited circulation suggests it served a specific, possibly experimental, purpose within that community. The manuscript was rediscovered in the twentieth century and edited by scholars such as Robert Pierpont Blake and later by the TITUS project. The calendar's structure follows the ancient system of seasonal hours, with day-length notes for each month.
