Letter 677: The man who preserves Helladius's household by his tireless efforts is this Martyrius here.

To Anatolius. (361) This man here, Martyrius, is the one who preserves Helladius's household by his labors in every matter. But the need for a man to attend once more to that very business for which he has come has made him run there. For he has come to stir up a sluggish suitor and either to lead him on to marriage or to send him off once he has changed his mind. If, then, you receive Martyrius, as is fitting for a man sent by us and on behalf of such affairs, all will go well for us.

Ἀνατολίῳ. (361) Ὁ σώζων Ἑλλαδίῳ τὸν οἶκον τοῖς περὶ ἕκαστα πόνοις Μαρτύριός ἐστιν οὑτοσί. τὸ δὲ δεῖν ἀνδρὸς εἰς ἐκεῖνο πάλιν ἐφ᾿ ᾧπερ ἥκει πεποίηκεν αὐτὸν τρέχειν. ἥκει γὰρ μνηστῆρα ῥᾴθυμον κινήσων καὶ ἢ πρὸς γάμον ἄζων ἢ μεταβεβλημένον ἀφήσων. ἢν οὖν ἴδῃς Μαρτύριον, ὡς εἰκὸς τὸν ὑφ’ ἡμῶν τε καὶ ὑπὲρ τοιούτων πεμφθέντα, πάνθ’ ἡμῖν ἕξει καλῶς.
