(Warning: music geekery ahead.)
The author of this site interprets the "doodle" at the top of the title page of Bach's "Well-Tempered Clavier" as an indication of the tuning to use -- quite convincingly.
Even if you aren't convinced, the articles he wrote are still interesting to read; lots of Bach information and references.
