Paul

“Nero sent Festus as [Felix’s] successor, and Paul was tried before him and brought as prisoner to Rome. Aristarchus went with him, whom he called his fellow prisoner in his epistles [Col. 4:10]. And at this point Luke, who wrote the Acts of the Apostles, finished his story with the statement that Paul spent two whole years in Rome in free custody, preaching without hindrance. After defending himself [successfully], the apostle is said to have set out again on the ministry of preaching and, coming a second time to the same city, found fulfillment in martyrdom. During this imprisonment he composed the second epistle to Timothy, mentioning both his earlier defense as well as his impending fulfillment” (Eusebius, The Church History, Translated by Paul L. Maier, 80).
