Saint Cyril
The lingua franca of the Western world in the early centuries of Christianity was the Koine Greek, and the Liturgy of Saint Mark was in such a language. The translation of this liturgy in Coptic, used by most of Coptic population at that time, is attributed to Saint Cyril of Alexandria in the first half of the 5th century. Thus the Greek version of this liturgy is usually known as "Liturgy of Saint Mark", while its Coptic version is regularly called "Liturgy of Saint Cyril", even if the formal name of the latter is "the Anaphora of our holy father Mark the Apostle, which the thrice-blessed Saint Cyril the Archbishop established".
