What is "artemon"

n. (context nautical English) A square sail, on a Roman oared ship?

Artemon (fl. ca. 230 AD), a prominent Christian teacher in Rome, who held Adoptionist, or Nontrinitarian views. We know little about his life for certain.

He is mentioned as the leader of a nontrinitarian sect at Rome in the third century. He is spoken of by Eusebius of Caesarea 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 and Theodoret 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. Both authors mention refutations: Eusebius an untitled work, Theodoret one known as The Little Labyrinth, which has been attributed to a Roman priest named Caius, and more recently to Hippolytus of Rome, the supposed author of the Philosophoumena.

Artemon, a Greek painter, who is recorded by Pliny to have painted a picture of Queen Stratonice, from which it is presumed that he lived about B.C. 300. He also painted ' Hercules and Deianira;' but his most celebrated works were the pictures which were carried to Rome, and placed in the Octavian Portico, representing 'Hercules received amongst the Gods;' and the 'History of Laomedon with Apollo and Neptune.'
