[edit] Possible break-up

When this box starts getting huge, as it already is - I suggest a breakup into three boxes, Mesolithic, Neolithic, Chalcolithic. Whoever designed the set of boxes is perhaps best qualified to do it - but, maybe there's another ace out there.Dave (talk) 11:04, 14 April 2008 (UTC)

[edit] Supplementary box

Hmm. I condensed it a lot so more would fit and added a touch of color. Not every article in the list can take this design conveniently. So, we need one that goes across the bottom. If any would care to undertake that I would appreciate it otherwise I will have a to grow a little more and do it myself.Dave (talk) 11:49, 15 April 2008 (UTC)
