Archei

Αγάθων ἔφη· “τὸν ἄρχοντα τριῶν δεῖ μεμνῆσθαι· πρῶτον μὲν ὅτι ἀνθρώπων ἄρχει, δεύτερον ὅτι νόμους ἄρχει, τρίτον ὅτι οὐκ ἀεὶ ἄρχει.”
(Stobaeus, Anth. 4.5.24)

Agathon said that the archon must remember three things, first that he rules over humans, second that he rules in accordance with the laws, and third that he does not rule for ever. (tr. John Stephen Wade)
