Sometimes you just stumble across good stuff that may stimulate that Writer's Muscle, completely by accident. I was reading Elizabeth Chadwick's blog Living the History today, and found this. It's in the latest entry. The title, The Senses in Late Medieval England, is kind of misleading, since it covers "earlier" medieval times as well. It's apparently a "scholarly" book, but the kind that, for writers writing in the period(or any other period a "scholar" may cover, which interests the writer), can add interesting detail that can help flesh out a story. It seems to have many examples, e.g. making the sign of the crosss when yawning, to prevent devils from entering the body through the mouth. Sounds wonderfully stimulating!
