Why would you need more than 1 in a location such as a military camp if you were measuring something
useful for ballistic to estimate distances. Dioptra were optical instruments, without lenses, used for measuring angles
a possible use of Roman Dodecahedra as rangefinders.

Are we guessing? This object has five knobs upon which it can stand no matter which way it is placed on a table. There are twelve positions that coincide with the Roman calendar that switched to 12 months in a year in 700 BCE. In order to keep this new calender fresh in the minds of the citizens, these dodecahedra were designed so that the current month would be positioned at the top. How's that for a stretch of the imagination?
