Mysterious Roman Dodecahedrons
The Roman dodecahedron is a small, hollow object made of bronze or (more rarely) stone, with a geometrical shape that has 12 flat faces. Each face is a pentagon, a five-sided shape. The Roman dodecahedra are also embellished with a series of knobs on each corner point of the pentagons, and the pentagon faces in most cases contain circular holes in them. More than 200 years after they were first discovered, researchers are no closer to understanding the origin and function of this mysterious object . Roman dodecahedra date from the 2nd or 3rd centuries AD, and typically range from 4cm to 11cm (1.57-4.33 inches) in size. To date, more than one hundred of these artifacts have been found across Great Britain, Belgium, Germany, France, Luxembourg, Netherlands, Austria, Switzerland, and Hungary. The great mystery is: how do they work and what do they do? Unfortunately, there is no documentation or notes about them from the time of their creation, so the function of the dodecahedra has not been determined. Nevertheless, many theories and speculations have been put forward over the centuries: candlestick holders (wax was found inside one example), dice, survey instruments, devices for determining the optimal sowing date for winter grain, gauges to calibrate water pipes or standard army bases, staff or scepter decorations, a toy to throw and catch on a stick, or simply a geometric sculpture .
