Oh, it's still being bandied about. Ran across it on cable TV within the last month or so, when I sampled an episode of "America Unearthed." Typical pastiche of dubious "science" and wild conjecture on all the usual suspect topics. . .

But back to the knight (and BTW love Artificer's pun a few posts back!), copper, and the covering-up of ancient stuff. One of our favorite UK sites is the Great Orme Copper Mine in northern Wales. Locals thought it was Victorian-era and were about to pave it over for parking -- do I sense a trend here? -- when it turned out to be Bronze Age. Well worth a stop if you're in the vicinity!
