we need a thousand light chariots with four horses each; a thousand leather-covered chariots, and one hundred thousand armoured men; and we must send supplies to distant fields. Wherefore the cost at home and in the field, the entertainment of guests, glue and lacquer for repairs, and necessities for the upkeep of waggons and armour are such that in one day a thousand pieces of gold are spent. With that amount a force of one hundred thousand men can be raised:-you have the instruments of victory.
