Venerable John Koukouzelis, the master chanter of the Great Lavra on Mount Athos.
John was born at Dyrrachion and, orphaned young, was taken into the imperial school of Constantinople for his remarkable voice, becoming the chief court singer. Longing for the monastic life, he fled secretly to the Great Lavra of Mount Athos, where he at first hid his identity and tended the goats.
Once recognized, he was allowed to remain and devoted himself to chanting and composition, becoming one of the chief masters of Byzantine music. Tradition relates that the Theotokos appeared to him after an all-night vigil and placed a gold coin in his hand in gratitude for his singing.

On the New Calendar, John Koukouzelis is commemorated on October 1. Churches on the Old (Julian) Calendar keep the feast on October 14 of the civil calendar.
