"Trusting to your indulgence I venture to take exception to your treating Sir Walter Scott's most noble verses in the 'Lay' as a translation of the Dies Irae ... My contention is that the Dies Irae supplied Scott with a suggestion, not an original; and that, setting out from that suggestion, he composed what is not only an original but very decidedly the grandest piece of sacred poetry in the English language; such a piece as would have compelled Johnson, could he have read it, to alter his doctrine respecting that kind of composition."
