We made the run up to Seattle for a quick over-nighter, to see the Pompeii Exhibit. Here is a little sketch, but much larger than real life, from the handle of a bronze jug. The tiny face is at the base of the handle, beautifully worked.
I haven't done much in just-pencil for a while. Should try it more.
I thought the items in the exhibit were wonderful -- I am especially taken with the household things. But, honestly, I didn't think too much of the presentation. Some items were labeled in puzzling ways, some items were displayed so that you could not see the details of the work, and some of the video screens weren't operating. It's unfortunate. Most folks will never have another look at these things.
