Saint Anthimus of Rome († c. 303), a presbyter and martyr, was a devoted Christian priest from Bithynia who faced persecution under Emperors Diocletian and Maximian. Known for his steadfast faith, he converted the Roman governor Pinianus while imprisoned, leading to the release of many Christian captives. After his release, Anthimus continued his ministry in Italy, performing miracles and winning converts. His unwavering commitment to Christ led to his martyrdom. His relics are venerated at St. Antimo’s Abbey in Tuscany. Celebrated for his courage and evangelistic zeal, his feast day is May 11 in the Catholic Church.
