Who wrote the book of Revelation — Meaning Explained

The author identifies himself as 'John' and was exiled on the island of Patmos 'for the word of God, and for the testimony of Jesus Christ.' Church tradition from the second century, including testimony from Irenaeus (who knew Polycarp, a disciple of John), identifies the author as the Apostle John, the same person who wrote the Gospel of John and the three Epistles of John. The book was likely written around AD 95 during the persecution under Emperor Domitian. Some scholars have proposed other Johns, but the traditional identification remains the majority view. John received the visions in a series of dramatic revelations and was commanded to write what he saw.
