Breaded codpieces

Well, this week you were going to get an irreproachably unsalacious back-to-school discussion of the word "pupil".

But then, as I was idly grocery shopping last weekend, I did a whiplash-inducing double take on passing one of the freezers emblazoned with a sign: 
"Breaded cod pieces, $10.99". 
Who knew what lurks at No Frills on the way from the bananas to the butter!

This, of course, got me thinking about codpieces. The WORD. (Please get your mind out of the gutter). Why is a codpiece called that? What do fish have to do with it (if anything)?

The "cod" in "codpiece" was an Anglo-Saxon word for a small bag, especially the round kind closed with a drawstring used as a purse or suchlike. This was opposed to a "sack" -- borrowed from Latin probably before the Anglo-Saxons left Germany-- which was a big bag. The word "bag" itself was borrowed a little later, from the Vikings.

Not surprisingly, by the 1400s, the word "cod" was being used for what the OED defines delicately as "The integument enveloping the testicles, the scrotum". This usage survived till the late 18th century.

In the late 1400s, men's tunics, which until then had covered the lower body well below the thighs, started getting shorter so that they no longer covered the crotch. What men wore under their tunic was essentially a pair of very long socks reaching to the waist but not sewn shut across the crotch like a pair of tights. You can see the problem. The fabric codpiece was invented to fill the gap, so to speak.

Being a lexicographer of unassailable virtue, I cannot imagine why the next development happened, but men actually started making their codpieces bigger and padding them. Eventually, in Spain, the codpieces became very large and vertical (you can go check this out on Google images by yourself). By the end of the 1600s, though, this fashion was mocked, and more concealing modes of dress took over.

What does all this have to do with fish? Probably nothing. The word "cod" in the fish sense cropped up in the 1300s, and is of uncertain origin.

Another usage of "cod" you may not be familiar with is a British one, also of uncertain origin, meaning "fake". The first time I came across this was in a review of the ballet Don Quixote, and I was most perplexed to know what on earth "cod-Spanish sets, costume and music" might mean.
