14 Having crowned himself with imperishable laurels, he returned to Moravia and his own people. He felt his death approaching and named his successor, and his last words exhorted the clergy and people to practice virtue. He departed in peace from this life, which had been the path to heaven for him. As Rome mourned Cyril, so Moravia mourned the loss of Methodius, showing its grief by giving his burial every honor.
