The Canterbury Tales by Geoffrey Chaucer
Not having done any Chaucer at school, reading The Canterbury Tales is one of those things I promised myself I would find time for and am pleased to have done at last! Although some parts are rather tedious six centuries or so later, it’s obvious why the popular bits are popular. I confess to having barely skipped through the Parson’s Tale (not a Tale at all, rather the sort of sermon that would send an entire congregation into a deep coma), but even the editor’s introduction describes it as "rarely read".
