Astragali were gaming pieces used in antiquity like dice or jacks, thrown in the air and caught on the back of the hand. Most commonly, they were made from the anklebones of sheep and goats (hence the name knucklebones), but examples made of bronze, stone, terracotta, as well as glass are also known.
