§5.23.1‘κατὰ τάδε ξύμμαχοι ἔσονται Λακεδαιμόνιοι 〈καὶ Ἀθηναῖοι〉 πεντήκοντα ἔτη.
'The Lacedaemonians and 〈Athenians〉 shall be allies for fifty years on the following terms.
ἢν [δέ] τινες ἴωσιν ἐς τὴν γῆν πολέμιοι τὴν Λακεδαιμονίων καὶ κακῶς ποιῶσι Λακεδαιμονίους, ὠφελεῖν Ἀθηναίους Λακεδαιμονίους τρόπῳ ὁποίῳ ἂν δύνωνται ἰσχυροτάτῳ κατὰ τὸ δυνατόν· ἢν δὲ δῃώσαντες οἴχωνται, πολεμίαν εἶναι ταύτην τὴν πόλιν Λακεδαιμονίοις καὶ Ἀθηναίοις καὶ κακῶς πάσχειν ὑπὸ ἀμφοτέρων, καταλύειν δὲ ἅμα ἄμφω τὼ πόλεε.
If any enemies invade the territory of the Lacedaemonians and do harm to the Lacedaemonians, the Athenians shall assist the Lacedaemonians in whatever strongest way they can, to the best of their power; and if they should depart after having ravaged the land, that state shall be an enemy to both Lacedaemonians and Athenians, and shall suffer harm from both, and both states shall bring the war to an end together.
ταῦτα δ’ εἶναι δικαίως καὶ προθύμως καὶ ἀδόλως.
These terms shall be observed justly, zealously, and without guile.
§5.23.2καὶ ἤν τινες ἐς τὴν Ἀθηναίων γῆν ἴωσι πολέμιοι καὶ κακῶς ποιῶσιν Ἀθηναίους, ὠφελεῖν Λακεδαιμονίους 〈Ἀθηναίους 〉 τρόπῳ ὅτῳ ἂν δύνωνται ἰσχυροτάτῳ κατὰ τὸ δυνατόν· ἢν δὲ δῃώσαντες οἴχωνται, πολεμίαν εἶναι ταύτην τὴν πόλιν Λακεδαιμονίοις καὶ Ἀθηναίοις καὶ κακῶς πάσχειν ὑπ’ ἀμφοτέρων, καταλύειν δὲ ἅμα ἄμφω τὼ πόλεε.
And if any enemies invade the territory of the Athenians and do harm to the Athenians, the Lacedaemonians shall assist 〈the Athenians〉 in whatever strongest way they can, to the best of their power; and if they should depart after having ravaged the land, that state shall be an enemy to both Lacedaemonians and Athenians, and shall suffer harm from both, and both states shall bring the war to an end together.
§5.23.3ταῦτα δ’ εἶναι δικαίως καὶ προθύμως καὶ ἀδόλως.
These terms shall be observed justly, zealously, and without guile.
ἢν δὲ ἡ δουλεία ἐπανιστῆται, ἐπικουρεῖν Ἀθηναίους Λακεδαιμονίοις παντὶ σθένει κατὰ τὸ δυνατόν.
And if the slave population should rise in rebellion, the Athenians shall assist the Lacedaemonians with all their might to the best of their power.
§5.23.4ὀμοῦνται δὲ ταῦτα οἵπερ καὶ τὰς ἄλλας σπονδὰς ὤμνυον ἑκατέρων.
These oaths shall be sworn on both sides by the very same persons who swore to the other treaty.
ἀνανεοῦσθαι δὲ 〈τὸν ὅρκον〉 κατ’ ἐνιαυτὸν Λακεδαιμονίους μὲν ἰόντας ἐς Ἀθήνας πρὸς τὰ Διονύσια, Ἀθηναίους δὲ ἰόντας ἐς Λακεδαίμονα πρὸς τὰ Ὑακίνθια.
And they shall renew 〈the oath〉 every year, the Lacedaemonians going to Athens at the time of the Dionysia, and the Athenians going to Lacedaemon at the time of the Hyacinthia.
§5.23.5στήλην δὲ ἑκατέρους στῆσαι, τὴν μὲν ἐν Λακεδαίμονι παρ’ Ἀπόλλωνι ἐν Ἀμυκλαίῳ, τὴν δὲ ἐν Ἀθήναις ἐν πόλει παρ’ Ἀθηνᾷ.
Both sides shall erect a stone pillar, one at Lacedaemon by the temple of Apollo in the Amyclaeum, and the other at Athens on the Acropolis by the temple of Athena.
§5.23.6ἢν δέ τι δοκῇ Λακεδαιμονίοις καὶ Ἀθηναίοις προσθεῖναι καὶ ἀφελεῖν περὶ τῆς ξυμμαχίας, ὅτι ἂν δοκῇ, εὔορκον ἀμφοτέροις εἶναι.
And if it should seem good to the Lacedaemonians and Athenians to add to or subtract anything from the alliance, whatever they agree upon shall be consistent with their oaths for both parties.'
