PlutarchOf the land which the Romans gained by conquest from their neighbours, part they sold publicly, and turned the remainder into common; this common land they assigned to such of the citizens as were poor and indigent, for which they were to pay only a small acknowledgment into the public treasury. But when the wealthy men began to offer larger rents, and drive the poorer people out, it was enacted by law that no person whatever should enjoy more than five hundred acres of ground.
