He is spoken of by Eusebius of Caesarea[1] as the forerunner of Paul of Samosata, an opinion confirmed by the acts of a Council of Antioch in 264, which connect the two names as united in mutual communion and support.
Eusebius and Theodoret[2] describe his teaching as a denial of Christ's divinity and an assertion that he was a mere man, the falsification of Scripture, and an appeal to tradition in support of his errors.
Eusebius' main account of Artemon is found in Ecclesiastical History Book V, Chapter XXVIII, and speaks as follows: For they say that all the early teachers and the apostles received and taught what they now declare, and that the truth of the Gospel was preserved until the times of Victor, who was the thirteenth bishop of Rome from Peter, but that from his successor, Zephyrinus, the truth had been corrupted.
And there are writings of certain brethren older than the times of Victor, which they wrote in behalf of the truth against the heathen, and against the heresies which existed in their day.
And how many psalms and hymns, written by the faithful brethren from the beginning, celebrate Christ the Word of God, speaking of Him as Divine.
