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
