Hi, Combat, you're right about Hollywood's choices for historical details, selecting them more for visual appeal than for accuracy. But I think there is actually more archeological and historical evidence than we Americans might be aware of, to support some of the details. The ancients aren't as popular a subject here as in Europe, especially since they're sitting on the old sites.
I'm going to check with my forum mates in some of the German forums I belong to, and see if I can find more details. I recall reading an article describing Roman clothing, both military and civilian, and the Romans actually had a very well-defined system of basic colors, and decorations, plus accessories, right down to the style of sandals or boots, that identified the wearer and his station in the social or military order.
I'm not saying blue is incorrect, but I'm curious to know more about it.
Prost!
Brad
