The Book of Revelation, often known simply as Revelation or The Apocalypse of John, is a book of the New Testament that occupies a central place in Christian eschatology. Its title is derived from the first word of the text, written in Koine Greek: apokalypsis, meaning "unveiling" or "revelation". The Book of Revelation is the only apocalyptic document in the New Testament canon (although there are short apocalyptic passages in various places in the Gospels and the Epistles).
