George Eliot as Prophetess

I'm currently reading Silas Marner, a stand-in for the excellent Middlemarch, which is this month's book club selection and which I've already read.

I'm still gathering my thoughts - in general I can say that I love how richly she develops all of her characters, and that nineteenth-century provincial England is surprisingly interesting - but I wanted to share a line that popped up early in the novel.

Writing of superstitions, medicine, and outsiders, Eliot writes:

There were women in Raveloe, at that present time, who had worn one of the Wise Woman's little bags round their necks, and, in consequence, had never had an idiot child, as Ann Coulter had.

Is it wrong that I found that so amusing?
