Narcissus Marsh was a member of the Irish Parliament that ordered the burning of Christianity not Mysterious (1696) by the public hangman in Dublin on 11 September 1697. Nonetheless, he retained a copy which still survives in the library he founded. Marsh has underlined the last four words of Toland’s assertion that “This I stand by still, and may add, I hope, that I have clearly prov’d it too” and noted waspishly in the margin:
‘You have often said it indeed, but yet proved nothing, unless saying a thing is so be proving it to be so’.
This annotation was not enough for him; Marsh was the one who commissioned Peter Browne to write a response, published as a A letter in answer to a book entitled, Christianity not mysterious as also, to all those who set up for reason and evidence in opposition to revelation & mysteries published in 1697.
