Peter of Atroa was an 8th-century abbot and saint who lived during a period of intense iconoclast persecution. Born Theophylact, he entered a hermitage in Phrygia at age eighteen, adopting the religious name Peter. He eventually became the leader of a monastery in Bithynia, founded by his mentor Paul the Hesychast. Throughout his life, he frequently moved between different regions, including Ephesus, Cyprus, and Cilicia, to protect his monastic communities from imperial efforts to destroy religious imagery.
