Can find web pages with date usage ranges from C7th BC to C16th AD, and C21st. The search was merely intended to quickly get an idea of the possible usage range. Each year on the time line was not checked out. There was an inactive page for C8th BC. Yes, this is a new usage for me. One that I'll be looking for in the future. George S.
