(Or Artemas).
Mentioned as the leader of an Antitrinitarian sect at Rome, in the third century, about whose life little is known for certain. He is spoken of by Eusebius (Hist. Eccl., V 28) as the forerunner of Paul of Samosata, an opinion confirmed by the Acts of a council held at Antioch in 264, which connect the two names as united in mutual communion and support. Eusebius (loc. cit.) and Theordoret (Haer. Fab., II, 4; V, II) describe his teaching as a denial of Our Lord'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. Both authors mention refutations: Eusebius and untitled work, Theodoret one known as "The Little Labyrinth", which has been attributed to a Roman priest Caius, and more recently, to Hippolytus, the supposed author of the Philosophoumena.
