Breviary of Glagolitic Liturgy

The Breviary of Glagolitic Liturgy is a medieval liturgical book used by Slavic churches that featured prayers, hymns, and psalms arranged for daily worship. Written in the Glagolitic script—one of the earliest Slavic alphabets—it reflects a unique cultural and religious tradition specific to the Slavic peoples, particularly in Croatia and nearby regions. This breviary served as a guide for clergy in performing church services, emphasizing both spiritual devotion and the preservation of Slavic linguistic and liturgical identity during the Middle Ages.
