Missionary and Scholar Cyril Dies in Rome
The Byzantine brothers Constantine and Methodius undertook missions among the Khazars and, beginning in 863, among the Slavs of Great Moravia. Constantine devised the Glagolitic alphabet and worked with Methodius to translate Christian texts into a Slavic literary language, challenging the assumption that worship should be confined to Greek, Latin, or Hebrew. The brothers traveled to Rome to defend their mission and seek approval for Slavic liturgy and clergy. Constantine entered monastic life there under the name Cyril. He died from illness in Rome on February 14, 869, leaving Methodius to continue their work in central Europe.
