According to Procopius, when the Persians are about to march to a war, the king sits on the throne and many baskets are set before him. The men of the army pass along the baskets one by one, each throwing one arrow in the baskets, which are then sealed with the king's seal. When the army returns to Persia, each man takes an arrow, and the number of casualties will be determined by the number of remaining arrows.[1]
