Mr. Cornwell, I am curious if you alluded to the archaic Irish word CALAD meaning "hard" or some other related Celtic word in your brilliant portrayal of Excalibur (old Caliburnus) from a chondritic or meteoric source in EXCALIBUR. I confess I can usually hardly wait to read any of your novels - Sharpe, Stonehenge, Arthurian, Grail, Saxon, whatever - as they are the best-crafted historical fiction one can find anywhere. In admiration, Patrick Hunt
I honestly don't know what the etymology is - the usual source is Caledfwylch (from memory, might have it slightly wrong) which is Welsh, but of course Welsh is very closely related to Irish, so I'm sure there is a connection . . .. alas, I don't know of it.
