John of Patmos is traditionally identified as the author of the Book of Revelation, the final book of the New Testament in the Christian Bible. He is believed to have been a Christian prophet who lived in the first century AD and was exiled to the island of Patmos in the Aegean Sea, where he received visions that he recorded in his writings. The Book of Revelation contains apocalyptic imagery and prophecies about the end times, including the return of Jesus Christ and the final judgment. John’s visions have been influential in Christian eschatology and have inspired various interpretations throughout history.
