A dark slate biconcave/biconvex two hole gorget. With its provenance in Mound Park - in the central grouping of the Portsmouth Earthworks Complex (Group B) - this slate gorget is thought to be a Hopewell ceremonial object. Such items have become known as gorgets, as they are thought to be decorative throat-pieces or neck-ornaments. How these gorgets functioned and their ceremonial significance, however, remains a mystery.
