This thread has thruout been getting bogged down by confusion between the two discourses represented by above exchange: viz

1. Which can be demonstrated by adducing an identifiable source in an accessible place? ~~ clearly Judas;

2. Which can be shown, or believed on fair evidence, to have the longest antecedence in terms of theme & narrative?; in which case King Orfeo, Riddles Wisely Expounded [leading to several others like CambricShirt/ScarboroFair or Capt Wedderburn being cited as clear offshoots of its theme], et al, must all be candidates.

So that disagreements like the above which are bound to occur, are category disputes.

Should not the original question be taxonimically defined in these terms by OP before the thread can become coherent?
