Digression Piece

A codpiece (from Middle English cod, "scrotum") is a covering flap or pouch that attaches to the front of the crotch of men's trousers and usually accentuates the genital area. It was held closed by string ties, buttons, or other methods. It was an important item of European clothing in the 15th and 16th centuries, and is still worn today in performance costume and in the leather subculture.
