Roman Museum Avenches, permanent exhibition (English text available at reception), proof of third-party translation
Bronze dodecahedron found in a house at Aventicum.The dodecahedron is a geometrical, three-dimensional figure, i.e. a regular polyhedron with twelve equal pentagonal faces. The object is hollow; each face is pierced and has a round opening of varying dimensions (0.9 cm to 2.6 cm). Ten openings are surrounded by concentric circles. The two largest openings, placed on two opposite faces, do not show any decoration. According to present knowledge, all recorded dodecahedra were found on Gallo-Roman sites, mainly north of the Alps and in particular in central and north-eastern Gaul. To date more than sixty pieces are known. Although no rare objects, dodecahedra are not common which explains the exceptional interest they raise. Generations of intrigued archaeologists have been trying to discover the possible use of the dodecahedra. Often they are classified as decorative object, part of a game or measuring instrument. It has also been suggested that they were used for religious purposes, but, so far, no dodecahedron has been found inside or near a sanctuary. New interpretations tend to consider the dodecahedron as an astronomical instrument. Thus the twelve faces would represent the twelve months and the thirty edges the days of a month. According to one recent theory, the dodecahedron served to determine a range of dates in relation to the spring and autumn equinoxes. |
