In job-market parlance my specialty is "seventeenth-century, non-dramatic." Like most people, though, my core competence is more like 50 years: I started with the English Civil War and worked backwards, rather successfully, and forward less successfully. Now I'm trying to learn me something about the Restoration--a period for which I've long had a reflexive dislike.
What I learned today: Nell Gwyn's nickname for the eventual James II was "dismal Jimmy."
I like it more already.
