Plato, Laws

[910a] and promise the founding of shrines to gods and demi-gods and children of gods; and through terrors caused by waking visions or by dreams, and in like manner as they recall many visions and try to provide remedies for each of them, they are wont to found altars and shrines, and to fill with them every house and every village, and open places too, and every spot which was the scene of such experiences. For all these reasons their action should be governed by the law now stated; and a further reason is this—to prevent impious men [910b] from acting fraudulently in regard to these matters also, by setting up shrines and altars in private houses, thinking to propitiate the gods privily by sacrifices and vows, and thus increasing infinitely their own iniquity, whereby they make both themselves and those better men who allow them guilty in the eyes of the gods, so that the whole State reaps the consequences of their impiety in some degree—and deserves to reap them. The lawgiver himself, however, will not be blamed by the god; for this shall be the law laid down:—Shrines of the gods no one must possess [910c] in a private house; and if anyone is proved to possess and worship at any shrine other than the public shrines—be the possessor man or woman,—and if he is guilty of no serious act of impiety, he that notices the fact shall inform the Law-wardens, and they shall give orders for the private shrines to be removed to the public temples, and if the owner disobeys the order, they shall punish him until he removes them. [910d] And if anyone be proved to have committed an impious act, such as is not the venial offence of children, but the serious irreligion of grown men, whether by setting up a shrine on private ground, or on public ground, by doing sacrifice to any gods whatsoever, for sacrificing in a state of impurity he shall be punished with death. And the Law-wardens shall judge what is a childish or venial offence and what not, and then shall bring the offenders before the court, and shall impose upon them the due penalty for their impiety.
