Back armour

Back armour, almost rectangular with the upper side slightly wider, is a masterpiece. It is used to cover the entire back. It is studded all over with pointed nails, and each is fitted to a square plate of steel. There are nine rows with five spikes in each row. It is padded with red velvet. There are four laces, one at each corner, with which it was tied with the body armour. It was worn over the shirt of mail.
