Dear Mad Doc Morris,
There was some very good experimental archeology, but most of the really interesting stuff was to be found in the crafts areas.
The cavalry presentation was very interesting in this respect. They have developed the saddles and techniques over time.
There was the "in-swinging" Cheiroballistra, which was the first that I have seen. I first read about that in a 2004 article called "Trajan’s artillery, The Archeology of a Roman Technological Revolution" by Dr. Michael Lewis, current World of Archeology.
I talked to a lady weaver, from Germany, Irene, who had made some cloth for Graham Sumners project. The Romans could weave very wide cloth and even make herringbone twill and dobby pattens. They had a very wide range of colours available.
Moulded glass, from an English company, was also very impressive.
