(according to Wikipedia) The most commonly accepted theory is that the dodecahedron was used as a measuring device. To be more precise, as a range measuring object on the battlefield. The theory suggests that the object was used to calculate the trajectory of projectiles on the battlefield. This is the reason the objects has different sized holes in the pentagrams. Similar theory suggests they were used as a surveying or leveling device. The problem is none of the theories has been supported by proof.
Another interesting theory is that the object was astronomic measuring instrument used for determining the optimal sowing date for winter grain. The angle of the sunlight can be measured with the device, and thereby one specific date in springtime, and one date in the autumn can be determined with accuracy. The dates could have been used for specific and important dates in agriculture, for example. The opposite of the theory is that the dodecahedron was different in size and arrangements.
A widely accepted and common theory is that the object was a religious artifact. This is based on the fact that most of the examples were found in Gallo-Roman sites. For example, one such object was found in a woman’s burial ground. There are also theories they were used as candlestick holders, since wax was found in many of the objects.
