I think the only truly medieval book I have is an excerpt from Bocaccio’s Decameron.  This should probably change.

While poking around the official SCA site, looking for the herbalist’s guild, and checking on what paperwork is required to pay membership dues, I found the SCA Marketplace, featuring a series of monographs called the Compleat Anachronist. 

Several of these would be very much appreciated cough**Christmas**cough:  (can we tell I’m trying not to be so hard to buy for? And they’re only 4.50 each!)

• CA0016 – A Compleat Herbal: Herbs as condiments and medicines, scents and dyes, their use and cultivation.
• CA0020 – Barbarian Cultures: Germanic Tribes, Slays, Magyars and Celts
• CA0025 – Gardens: Medieval gardens then and now – plants, construction and trivia.
• CA0027 – Herbs II, an Herbal Grimoire: Fragrances, foraging, dyes, herbal medicine and cosmetics, insect repellent, supplies and suppliers.
• CA0021 – Dyestuffs: Medieval dyeing methods and materials
• CA0043 – A Palette of Period Pigments: Colors used by medieval artists and modern recipes to reproduce
  them, includes bibliography and Pantone<®> (PMS) color references.

That’s a start.  I also would like my own copy of the Known World Handbook.
