Place your bets. Less than half an inch wide, this finely wrought, cubical die exhibits the same arrangement of numbers on its faces as on a standard modern die. The exposed faces show a one, four and five; the unexposed faces bear a six opposite the one and a three and two opposite the four and five respectively. As in modern dice, the numbers consist of groups of dots, with each dot on this die surrounded by two concentric circles. The excellent symmetry of the circles strongly suggests that they were incised with a center-bit scriber, a tool that has a cutting element set at a fixed radius from a center point, similar to a compass.
