(1) A silversmith in Ephesus whose livelihood came from making “silver shrines” of the goddess Artemis (Acts 19:23–41). Worried that Paul’s preaching would end his business and that of his fellow craftsmen, Demetrius stirred a local crowd into frenzied support of Artemis. As a result, Paul’s missionary companions Gaius and Aristarchus were seized by the crowd and taken into the local theater. Calm came only with the intervention of the city clerk, who suggested that Paul had not actually spoken against Artemis, and that the proper place for Demetrius to air his grievances was a court. (2) In 3 John, a Christian of good repute in the church who was commended to the recipients of the letter with high praise (v. 12).
