Zachary of Vienne was an early Christian presbyter who served as the second bishop of Vienne, located in modern-day France. Living during the first century, he is recognized as one of the primary evangelists in the region. According to tradition, he led his community during the reign of Emperor Trajan. His life and ministry concluded when he was martyred in 106 AD by the Prefect Pompey, as Christianity was not permitted within the Roman Empire at that time.
