Title, authorship, and date

The author names himself as simply "John" in the text, and states in Revelation 1:9 that he is on the island of Patmos, and so he is conventionally called " John of Patmos ". He was a Jewish–Christian prophet, probably belonging to a group of such prophets, and was accepted by the congregations to whom he addresses his letter. The New Testament canon has four other " Johannine works " ascribed to authors named John, and a tradition dating from Irenaeus (c. 130 – c. 202 AD) identifies John the Apostle as the author of all five. The modern academic consensus is that a Johannine community produced the Gospel of John and the three Johannine epistles, while John of Patmos wrote the Book of Revelation separately.
