Saint Nitus was the son of the martyrs Terence and Neonilla. He and his family suffered martyrdom during a persecution of Christianity under the emperor Decius (249-250). They zealously confessed Christ and denounced idolatry. For this the pagans subjected the entire Christian family to terrible tortures and torments, but failed to get them to renounce the true Faith. So, the holy martyrs were beheaded, and received crowns of martyrdom.
