American Tract Society Bible Dictionary
1. A goldsmith of Ephesus, who made models of the famous temple of Diana at Ephesus, which he sold to foreigners, Acts 19:24-4 . Observing the progress of the gospel, not in Ephesus only, but in the regions around, he assembled his fellow-craftsmen, and represented that, by this new doctrine, not only their trade would suffer, but the worship of the great Diana of Ephesus was in danger of being entirely forsaken. This produced an uproar and riot in the city, which the town clerk with difficulty appeased by firmness and persuasion.
2. A disciple, and probably a minister, of high repute, 3 John 1:12 . He may have been formerly the silversmith of Ephesus; but this can be neither proved nor disproved.
