Cyrillic

Under the impact of missionary expansion from Byzantium into regions dominated by Slavic language groups, there were devised modifications of Greek uncials by which those languages, and hence texts useful for missionary enterprise both biblical and liturgical, could be rendered into written form. Tradition ascribes the creation to ninth-century activities of SS. Cyril and Methodius, from the former of whom this particular script (still used for Slavonic languages) receives its name.
