Dice divination, know technically by the term astrogalomancy, comes from the Greek word, astragalos, which means ‘dice’ or ‘knucklebone.’ The original dice consisted of small bones, usually sheep bones. In ancient times, these bones were marked with special symbols or letters of the alphabet, then either tossed onto the pages of a picture book, or into a drawn circle or some other kind of boundary, which was often marked with magical or divinatory symbols. A reading was taken from how the dice landed, what symbol, if any, they landed on, and which side landed face up. Astragalomancy was very popular in Mesopotamia, and African tribes have practiced it from ancient times up to the present day.
Today, of course, we use the modern six-sided dice. A few methods of modern dice-casting use many-sided dice, but we will focus on the six-sided dice. Most ancient occult traditions say Mondays, Tuesdays, Wednesdays, Thursdays and Saturdays and the most favorable days of the week for casting the dice, and that it should not be attempted on Fridays and Sundays. Other sources say dice-casting should not be attempted on Mondays and Wednesdays. I cast the dice on Sundays, as Sunday is the most peaceful and relaxed day of the week for me.
Dice divination is not a method that lends itself to answering specific questions. The only question you can ask the dice is something along the lines of ‘What of any significance is going to happen to me in the next week?’ It gives only a general prediction about what is going to happen in the next seven to nine days.
