Aristarchus of Thessalonica

Aristarchus or Aristarch (Ἀρίσταρχος Aristarkhos), "a Macedonian of Thessalonica" (Acts 27:2), was an early Christian mentioned in a few passages of the New Testament. He accompanied Saint Paul on his journey to Rome. Along with Gaius, another Roman Macedonian, Aristarchus was seized by the mob at Ephesus and taken into the theater (Acts 19:29). Later, Aristarchus returned with Paul from Greece to Asia. At Caesarea, he embarked with Paul on a ship of Adramyttium bound for Myra in Lycia ; whether he traveled with him from there to Rome is not recorded. Aristarchus is described as Paul's "fellow prisoner" and "fellow laborer" in and, respectively.

Background

Aristarchus son of Aristarchus, a politarch of Thessalonica (39/38 BC?) may be the same person with Aristarchus.
