An apocalypse (Ancient Greek: ἀποκάλυψις apocálypsis, from ἀπό and καλύπτω meaning 'un-covering'), translated literally from Greek refers to a revelation of something hidden, although this sense did not enter English until the 14th century.[1] In religious contexts it is usually a revelation of hidden meaning - hidden from human knowledge in an era dominated by falsehood and misconception.
