12th-century hairstyles

From the Dictionnaire raisonné du mobilier français de l’époque carlovingienne à la Renaissance (Reasoned dictionary of French furniture from the Carolingian era to the Renaissance), vol. 3 by E. Viollet-Le-Duc. Paris, 1874, which can be browsed at the Internet Archive, and which appears to have lots more neat stuff in it.

Wow. After posting the above, I went back and clicked through 350 pages of this book.  It's an incredible repository of period information (wish I could read French).  Here are some additional illustrations of ladies hairstyles, but the book also covers other fashion from sandals to codpiecees to crowns.  And it's just volume three of a set.
