What do dodecahedrons do?

Roman artifacts are still a mystery after 300 years.

Some suggestions:

  • A specific type of dice for a game since lost to history.
  • A magical object, possibly from the Celtic religion. A similar small, hollow object with protrusions was recovered from Pompeii in a box with either jewellery or items for magic.
  • A toy for children.
  • A weight for fishing nets.
  • The head of a chieftain’s scepter.
  • A kind of musical instrument.
  • A tool to estimate distances and survey land, especially for military purposes.
  • An instrument to estimate the size of and distance to objects on the battlefield for the benefit of the artillery.
  • A device for detecting counterfeit coins.
  • A calendar for determining the spring and autumn equinoxes and/or the optimal date for sowing wheat.
  • A candle holder. (Wax residue was found in one or two of the objects recovered.)
  • A connector for metal or wooden poles.
  • A knitting tool specifically for gloves. (That would explain why no dodecahedrons were found in the warmer regions of the Empire.)
  • A gauge to calibrate water pipes.
  • A base for eagle standards. (Each Roman legion carried a symbolic bird on a staff into battle.)
  • An astrological device used for fortune-telling. (Inscribed on a dodecahedron found in Geneva in 1982 were the Latin names for the 12 signs of the zodiac.)

While theAbysmal has no suggestion, the two underlined time-related suggestions are most intriguing.
