Cleromancy
Cleromancy (Greek klēros, lot) is divination by drawing lots: stones, dice, sticks, bones — any random throwing of objects. One of the most universal forms, present in all known cultures. The casting of lots is documented in the Bible (Joshua 7:14, Acts 1:26), in Homer and in modern oracles such as the I Ching.
