I did take a bit of a look in some of the Gnostic gospels. Marcion had the destruction of the temple but not a word on the Abomination of Desolation. Perhaps it was in the "Q".
I still wonder how the Mosiach was equated with the "Man of Sin" in Paul's letters? Later, he is referred to as Anti-Christ in John's Revelation and where another character is introduced...the False Prophet. It's interesting that both are physically thrown in the "Lake of Fire" which is neither Hell or Hades.
