One of the seventy disciples and bishop of Lystra, according to Dorotheus (Bibl. Maxima (Lugd. 1677), III, 429). He is mentioned in Titus 3:12 as one of the faithful companions of Paul. The name is probably Greek, a masculine form of Artemis, or, as has been suggested, a short form of Artemidorus, a common name in Asia Minor. These contracted forms were by no means rare in the Greek world. The Athenian orator, Lysias, was doubtless named after his grandfather, Lysanias, and at first may even have been called Lysanias himself.
