Since kings used to be responsible for the provision of public goods (irrigation, streets, town walls, parks and other environmental goods) the distinction between public and private was not quite the same in the ancient world as it is in the modern world.
王は公共財 （灌漑、街路、町の壁、公園および他の環境財 ）の供給に対し責任があったので、公のものと私的なものとの間の区別は現代の世界のそれと全く同じではなかった。
