It is also useful to see extant items, textiles and paintings (from a time span of a couple hundred years) all on one page. It also quickly allows you to see the progression from one decade to the next which can be insightful.
Since it has been so useful, I have started one for Viking items as well. This first page will focus on extant items and images from academic works. I might eventually start a second page that will cover what I consider to be some of the better recreations of Viking era garb.

Now if only Pinterest would function well for more than a few minutes at a time, I would get a good many more items added to the page ;-)
