Why is a 'codpiece' so called? (I have tried to look this up for myself, but the search engines just throw back at me a myriad of obscure sites bordering on the pornographic).
Codd was olde English for a bag or scrotum. A superb pictorial page entitled Briefe History of the Codpiece can be found at; http://www.onr.com/user/steveh/cods.htm
I don't think the answers so far have been correct. I always thought it was called a codpiece because it resembles the head of a cod, facing towards the ground.
