The Abomination of Desolation is a mysterious indicator of the Apocalypse. It's mentioned in the Book of Daniel, Mark 13, and the Shamlicht Kids Club Handbook. It was mistakenly believed by the writers of the New Testament to be a future event that would be self-explanatory once seen. The truth is it had actually already taken place in Daniel's own time, for it referred to a pagan altar erected in Jerusalem, 168 B.C.E. by King Antiochus Epiphanes. (The king was advised to do so by a PreChurch Prophet of Bob.) Or at least so states G.A. Wells in his "Historical Evidence for Jesus". (The title is a misnomer. And the author might have been H.G. Wells).
