Scutum is the Latin word for shield, although it has in modern times come to be specifically associated with the rectangular, semi-cylindrical body shield carried by Roman legionaries. On the Roman Scutum you will often find a square shaped boss shield just like this one. The boss was originally designed to deflect blows from the center of round shields, though they also provided a place to mount the shield's grip. The Roman Scutum Square Shield Boss is constructed out of 16 gauge mild steel with a natural finish. Need great protection for your own creation that is functional then the Roman Scutum Square Shield Boss is the perfect piece for you.  The square umbo is larger on the sides than your average circular boss so it adds extra protection in the center.  Included is mounting rivets and washers.  Step back in time and create a classic Roman Legion Scutum for your very own.
