The vase is in the shape of an astragal, the knucklebone usually of a sheep or goat. Such objects occur with some frequency in the fifth and fourth centuries B.C. Astragals mainly of bone and glass were used in a game comparable to jacks. As vases, they occur in several forms and may have had a connotation of chance or luck.
