I disagree I am absolutely sure that you are not an idiot And I beg your pardon for not coming back to you sooner Concerning the challengers I m with Tilman Nagel here I find it difficult to believe that sometime in the seventh or eighth century AD a few people sat down together and invented a good 150 years of past history On the other hand even Nagel has Crone on his reference list She may hold minority views but she is a respected scholar It is okay with me that the IP removed that statement if however the statement could be referenced to someone like Crone it certainly should be put back in again Cheers
