Plato, Laws 910d

οἱστισινοῦν, ὡς οὐ καθαρὸς ὢν θύων θανάτῳ ζημιούσθω. τὸ δὲ παίδειον ἢ μὴ κρίναντες οἱ νομοφύλακες, εἰς τὸ δικαστήριον οὕτως εἰσαγαγόντες, τὴν τῆς ἀσεβείας δίκην τούτοις ἐπιτελούντων.

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.
