John is considered to have been exiled to
Patmos during a time of persecution under the Roman rule of
Domitian in the late 1st century. states: "I, John, both your brother and companion in tribulation...was on the island that is called Patmos for the word of God and for the testimony of Jesus Christ."
Adela Yarbro Collins, a biblical scholar at
Yale Divinity School, writes: Early tradition says that John was banished to Patmos by the Roman authorities. This tradition is credible because banishment was a common punishment used during the Imperial period for a number of offenses. Among such offenses were the practices of magic and astrology. Prophecy was viewed by the Romans as belonging to the same category, whether Pagan, Jewish, or Christian. Prophecy with political implications, like that expressed by John in the Book of Revelation, would have been perceived as a threat to Roman political power and order. Three of the islands in the
Sporades were places where political offenders were banished. (Pliny,
Natural History 4.69–70; Tacitus,
Annals 4.30) According to
Tertullian (in
The Prescription of Heretics) John was banished after being plunged into boiling oil in Rome and suffering nothing from it. == Book of Revelation ==
