Philosopher, who wore the garb of the philosophers, from the eparchy of Neapolis↗ [Nablus] in Palestine.1 His father was Priscus, son of Bacchius. This man strove diligently for the religion of the Christians; so much so that he even gave to Antoninus (surnamed Pius)2 and his sons and the Senate of the Romans a book composed Against the Pagans, without being ashamed at the ignominy of the cross.3 He also wrote a second book, which he gave to the successors of Antoninus, namely Marcus Antoninus and Lucius Aurelius Commodus.4 There is also another book of his against the pagans, which he entitled Confutation, and another On the Monarchy of God,5 and another, which he named Psalmist, and another On the Soul, and a dialogue Against the Jews, which he held with Trypho, the leader of the Jews at Ephesus↗.6 Furthermore he published notable volumes against Marcion,7 and another book Against All the Heresies, which he mentions in the Apology which he gave to Antoninus Pius. Holding his debates at Rome, he reprimanded Crescens the Cynic who blasphemed against the Christians and called him gluttonous and profligate and licentious and afraid of death. Finally by this man's efforts and plotting he suffered as a Christian on behalf of Christ.
