Aristarchus, whose name means “best ruler” or “best prince,” was a fellow worker with the apostle Paul. He is first mentioned in the book of Acts during the riot in Ephesus. Both Gaius and Aristarchus, described as “Paul’s traveling companions from Macedonia,” were seized by the angry mob (Acts 19:29). Paul’s preaching had upset Demetrius and other metalworkers who made idols of Artemis for a living (Acts 19:21–27). It seems the mob couldn’t find Paul, so they seized Paul’s fellow workers instead. Aristarchus and Gaius were in a precarious position until, two hours later, the city clerk was finally able to persuade the crowd to disperse.
