Mammes of Caesarea was a third-century Christian martyr born in Caesarea to parents who were imprisoned for their faith. Following the execution of his parents, Theodotus and Rufina, he was raised by a wealthy widow. According to tradition, the young boy faced significant persecution from the Roman governor and Emperor Aurelian. Legendarily, he was eventually killed by Duke Alexander after surviving encounters with lions, which he reportedly tamed through his preaching.
