I'd like to point out that the comment that the medical techniques were forgotten in Europe "probably because of the disapproval of religious authorities" is gratuitous and otiose. This comment does not reflect the more tentative wording of Christopher Albury's speculation, that "This might have been because it was not approved by the religious authorities at the time who might have considered him interfering with God's work."

Mr Albury is associated with the auction house, and there is no indication in the Daily Mail article that he is a historian and doing anything more than speculating ("this might ... who might..."). To repeat his speculations with more certitude (replacing his "might" with "probably") merely creates misinformation and reflects prejudice.
