A Boeotian shield is a large hand-held shield once carried by warriors in Ancient Greece. It is similar to the more commonly encountered aspis in that it has an overall circular shape, but differed in having scooped indentations at both sides. The term "Boeotian" as applied to this armament is a modern construct resulting from its frequent appearance on ancient Boeotian coins. No shield of this type has physically survived into the modern era, but this type, along with the Boeotian helmet, are considered characteristic of the warriors of Boeotia.
