Just saw this op-ed in The Daily Telegraph (UK), in which the writer talks about how much he loves the "medieval."
I'm not sure about his history but I'm pretty sure "medieval" predates 1827 and I'm pretty sure that this author is not alone in "rescuing" the word "medieval" from its Pulp Fiction-related evilness. I'm darn sure that the 2 books he mentions are not the first to appear on modern medievalism (although they both do sound interesting). Anyway, despite the op-ed's laudatory tone for 19th-century medievalism, the author may also want to look at this book by Elizabeth Siberry. It documents the use of the crusades in the colonial enterprise. I know, it complicates a nice story, but doesn't reality always do that?
