Eschatology literally means the study of the eschaton, the times of the end, 'last things', or 'end times.' In Zoroastrianism, Christianity and in Norse pagan theology, eschatology refers to a theology concerning the end of the world, as predicted in the prophecies of these faiths, and as recorded in their sacred texts. Eschatology also refers to the study of general afterlife concepts of other religions, especially the western monotheistic faiths. In this broader sense, eschatology can refer to the messiah, a messianic era, the afterlife, and the soul in religions which have such beliefs.
As far as we know, Zoroastrianism had a fully developed concept of the end of the world as being devoured by fire already in 500 B.C. and is thus the oldest eschatology we know of.
