Between 232 and 235, while in Caesarea in Palestine, Origen wrote On Prayer, of which the full text has been preserved in the original Greek. After an introduction on the object, necessity, and advantage of prayer, he ends with an exegesis of the Lord's Prayer, concluding with remarks on the position, place, and attitude to be assumed during prayer, as well as on the classes of prayer. On Martyrdom, or the Exhortation to Martyrdom, also preserved entire in Greek, was written some time after the beginning of the persecution of Maximinus in the first half of 235. In it, Origen warns against any trifling with idolatry and emphasises the duty of suffering martyrdom manfully, while in the second part he explains the meaning of martyrdom.
