I never said that about Keith Chandler's book or any of his interpretation for that matter. I suggest you read my post more carefully before attributing something to me. All I stated was that his book addressed many of the myths (meaning possible origins). No implication on his thoughts of when it originated was implied - I just put down what was in the title. I will admit that I did make a mistake. The dates should have read 1660 - 1900.
The full title of the book is
"Ribbons, Bells and Squeaking Fiddles" - The Social History of Morris Dancing in the English South Midlands, 1660-1900.
I would add that the book looks well written and very readable - I would like to get my own copy (if it is still in print) which would give me more time to read it.
