What it is
The life of the missionary called Cyril, who devised an alphabet for the Slavs, translated the liturgy, and defended vernacular worship against those who allowed only three sacred languages.
Why it lasted
The founding document of Slavic Christianity and one of the great arguments in Christian history for worship in a people's own tongue.
