Pertaining to the last or final things.

Pertaining to the end of history as we know it, sometimes spoken as the end of time. It relates to those religious traditions (primarily Western religions) that speak of a final end or culmination to human history, which is said to involve a cosmic judgment of persons in relation to the expectations of God and a final apportioning of justice in which each is expected to receive what he most truly deserves. There is no such conception in traditions (such as Eastern religions) which conceive cosmic time as cyclical rather than linear or non-repeating.

(ES·cha·to·LOG·ical). Relating to eschatology, from the Greek ta eschata, "the last things," and in reference to the end time or the closing of the present age.
