A six part series on the Renaissance, which apparently has never been rerun or released on DVD *cough*. All I could find on it was a review from the Telegraph which is ranty, dishonest, and poorly-argued even by "Hitler was left-wing" Telegraph standards. ("standards").
Pleasantly-written narration, good camera work, and tasteful pacing make this both extremely relaxing and extremely exciting. I couldn't recommend it more strongly.
