Martyrdom
The surviving account of Antonina situates her in Nicaea during a persecution of Christians under Maximian. Presenting herself and confessing her faith, she was cast into prison when the authorities could not compel her to renounce Christ and sacrifice to idols. The tradition describes successive torments: she was hung up and her sides were torn, and she was placed on a red-hot bed or lit grill, from which she is said to have emerged unharmed. The hagiography reports angelic intervention against those who came to strip and beat her. Her martyrdom was completed when she was sewn into a sack and sunk in the lake of Nicaea. A liturgical verse preserved in her commemoration draws on the manner of her death: 'The sea has become a nuptial chamber, covering Antonina the bride of the Lord.'
