Why did the apostle Paul’s preaching in Ephesus cause an uproar among the silversmiths?

 
The silversmiths of Ephesus prospered by making “silver shrines of Artemis,” patroness of Ephesus, a goddess of hunting, fertility, and childbirth. (Acts 19:24) Her image was reputed to have fallen “from heaven” and was housed at the temple of Artemis in Ephesus. (Acts 19:35) This temple was viewed as one of the seven wonders of the ancient world. Crowds of pilgrims flocked to Ephesus during March/April each year to attend festivals honoring Artemis. The influx of visitors generated demand for cult objects, used either as souvenirs, amulets, or offerings to the goddess or for family worship once the pilgrims returned home. Ancient inscriptions from Ephesus speak of the manufacture of gold and silver statues of Artemis, and other inscriptions specifically mention the silver-worker’s guild.
 
Paul taught that images “made by hands are not gods.” (Acts 19:26) Thus, the silversmiths saw their livelihood threatened and fomented a riot to protest Paul’s preaching. Demetrius, one of the silversmiths, summed up their fears, saying: “The danger exists not only that this occupation of ours will come into disrepute but also that the temple of the great goddess Artemis will be esteemed as nothing and even her magnificence which the whole district of Asia and the inhabited earth worships is about to be brought down to nothing.”—Acts 19:27.
