The Roman "turricula"
It is a bronze turret dating back to the 4th century. A.D. (found in Germany in 1985) used to play dice without cheating.
The dice, introduced by the player in the upper part of the structure, randomly rolled between the internal slats exiting the lower part.
The perforated writing reads "Pictos victos, hostis deleta, ludite securi", that is "The Picts have been defeated, the enemy destroyed, play calmly".
