Plato, Laws 880c

τὴν δίκην, δεδέσθω μηδὲν ἐνιαυτοῦ σμικρότερον· ἐὰν δὲ οἱ δικασταὶ τιμήσωσιν πλείονος, ἔστω κύριος ὁ τιμηθεὶς αὐτῷ χρόνος. ἐὰν δὲ ξένος ἢ τῶν μετοίκων τις τύπτῃ τὸν πρεσβύτερον εἴκοσιν ἔτεσιν ἢ πλείοσιν ἑαυτοῦ, περὶ μὲν τῶν παραγενομένων τῆς βοηθείας ὁ αὐτὸς νόμος ἐχέτω τὴν αὐτὴν δύναμιν, ὁ δὲ τὴν τοιαύτην δίκην ἡττηθείς, ξένος μὲν ὢν καὶ μὴ σύνοικος, δύο ἔτη δεδεμένος ἐκτινέτω ταύτην αὐτὴν τὴν δίκην, ὁ δὲ μέτοικός τε ὢν καὶ ἀπειθῶν τοῖς νόμοις τρία

he shall be imprisoned for not less than a year; and if the judges assess the penalty at a longer period, the period so assessed shall be binding on him. And if a Stranger or a resident alien beat a man older than himself by twenty or more years, the same law regarding help from bystanders shall be equally binding; and he that is cast in a suit of this kind, if he be a non-resident Stranger, shall be imprisoned for two years and fulfil this sentence; and he that is a resident alien and disobeys the laws shall be imprisoned for three years, unless the court assess his penalty at a longer period.
