A native of Paphlagonia, of Christian parents. His parents were thrown into prison, for Christ's sake. His father first passed away there, and then, after she gave birth to him, so did his mother. So he remains like a baby in a dungeon among the dead bodies of his parents. An angel of God appeared in a dream to the widow Amia and told her to take the child from the dungeon. Amija raised him in the Christian spirit, and he was extremely bright at school. During the persecution under Emperor Aurelian, Mammantus, who was only 15 years old, was brought before the emperor. Since he did not want to renounce Christ, they beat him with clubs and threw him into the sea. Angel saves him and takes him to the mountain near Caesarea. But they found him there too, so some idol priest pierced him with a trident. His relics are miraculous.
