Winter* & Savoy isn't as bad as people say. There isn't much in the way of direct reference, but the longer I study the real deal, the more in that book comes out to be accurate.

However, it isn't meant to be scholarly. It was meant to show Renaissance Faire participants how to get the look.

*note: Janet Winter does not spell her name with an S. She was one of the first Laurels in the SCA, Mistress Janet of Breakstone. Great Lady, always happy to share her knowledge and a good joke.
