Please keep in mind that archeological evidence is continually being cataloged, studied and interpreted. In which case, there is always the chance of conflicting results or changes in theories. It’s something to keep in mind for when ideas clash. There is also so little known that a lot of speculation has to happen. One of the neat things about being in the SCA or any historical reenactment group is that we get to go test drive a lot of these theories. That being said, here are some sources for you to begin with.
