In August, I blogged (link, link) about the methods anthropologists use to determine the age of ancient ceramics.
is an article about a brick from Roman times that turned up at Fort Vancouver. The
brick may have been part of a cobblestone street or Roman ruin in Great Britain.
Historians speculate that during Colonial times, the brick was recycled for use
as ballast in an English ship that traveled to British Columbia. The brick is
adorned with the paw prints of an ancient Roman cat that stepped in the wet
clay about 2000 years ago.
