Slavonic holds second place, numerically, among the liturgical languages in which the Mass and the Divine Office are said. About 866 Saint Cyril and Saint Methodius translated the liturgy of the Byzantine Church into old Slavonic, written in the Cyrillic alphabet for the benefit of their Slavic converts. Shortly afterwards, the Roman Mass was translated into Slavonic and written in an older alphabet called Glagolitic. The Greek, or Byzantine, Rite in this ancient language is now used among Slavs, whether Catholic or Orthodox, and the Roman liturgy in Slavonic is still celebrated in Dalmatia and Croatia.
