7-sided Dice from the 13th century
Two styles of 7-sided dice based on those portrayed in the "Book of Games" a manuscript commissioned by Aphonso X circa 1280 A.D. One is a 7-sided "log" die about 2" long, the other is a short polygon with 5 square faces and two five-sided faces. approximately 3/4." Molded in resin to simulate bone or ivory.
They were used with a form of 7-player Backgammon and a variation on Chess which was played on a board 10 squares on each side and extra pieces, the dice were used to determine which Chess piece you could move.
These dice can land with one corner facing up, so they were apparently scored by counting the the upper-most side that lands facing the player who rolled the die.
Although we are attempting to simulate hand-made dice based on a historic example, we took our master copies of these dice to a modern machine shop to mill the faces accurately in order to make them as random as possible.
When rolling the pentagonal die you can feel which way it is facing in your hand and effect the outcome. Therefore to get a more random result we recommend using some form of dice cup.
The "log" version works best if you "roll" it out of your hand rather than "throwing" it.
