Apocalypse (from Ancient Greek ἀποκάλυψις (apokálupsis) 'revelation, disclosure') is a literary genre originating in Judaism in the centuries following the Babylonian exile (597–587 BCE) but persisting in Christianity and Islam.
[1] The means of mediation include dreams, visions and heavenly journeys,[2] and they typically feature symbolic imagery drawn from the Jewish Bible,[3] cosmological and (pessimistic) historical surveys, the division of time into periods, esoteric numerology, and claims of ecstasy and inspiration.
[13] It has been defined by John J Collins as "a genre of revelatory literature with a narrative framework, in which a revelation is mediated by an otherworldly being to a human recipient, disclosing a transcendent reality which is both temporal, in that it envisages eschatological salvation, and spatial, insofar as it involves another, supernatural world.
"[14] Collins later refined his definition by adding that apocalypse "is intended to interpret present, earthly circumstances in light of the supernatural world and of the future, and to influence both the understanding and the behaviour of the audience by means of divine authority.
[16] Apocalyptic revelations are typically mediated through such means as dreams and visions (the ancient world did not distinguish between these), angels, and heavenly journeys.
