Laudator Temporis Acti

Herodian 2.11.2 (tr. Edward C. Echols; he = Severus):

He shared personally in their hardships, sleeping in an ordinary army tent and eating and drinking whatever was available to all; on no occasion did he make use of imperial luxuries or comforts. As a result, he enjoyed even greater popularity among the troops; respecting him not only for sharing their hardships but also for overcoming all difficulties, they carried out his orders with enthusiasm.

ἐκοινώνει δὲ τῶν καμάτων αὐτοῖς, σκηνῇ τε χρώμενος εὐτελεῖ, καὶ σιτία καὶ ποτὰ προσφερόμενος οἷα καὶ πᾶσιν ὑπάρχειν ἠπίστατο· οὐδαμοῦ δὲ τρυφὴν ἐνεδείκνυτο βασιλικήν. ὅθεν καὶ μείζονα παρὰ τῶν στρατιωτῶν εὔνοιαν ἐπιστώσατο· οὐ γὰρ μόνον αὐτὸν συμπονοῦντα ἀλλὰ καὶ τῶν καμάτων ἄρχοντα οἱ στρατιῶται αἰδούμενοι μετὰ προθυμίας πάντα ἔπραττον.

Plutarch, Life of Marius 7.5-6 (tr. Rex Warner, rev. Robin Seager):

Indeed it seems generally to be the case that our labours are eased when someone goes out of his way to share them with us; it has the effect of making the labour not seem forced. And what a Roman soldier likes most to see is his general eating his ration of bread with the rest, or sleeping on an ordinary bed, or joining in the work of digging a trench or raising a palisade. The commanders whom they admire are not so much those who distribute honours and riches as those who take a share in their hardships and their dangers; they have more affection for those who are willing to join in their work than for those who allow them to take it easy.

ὅλως μὲν γὰρ ἔοικε τοῦ κάμνειν ἑκάστῳ παραμυθία τὸ συγκάμνον ἑκουσίως εἶναι· δοκεῖ γὰρ ἀφαιρεῖν τὴν ἀνάγκην· ἥδιστον δὲ Ῥωμαίῳ θέαμα στρατιώτῃ στρατηγὸς ἐσθίων ἐν ὄψει κοινὸν ἄρτον ἢ κατακείμενος ἐπὶ στιβάδος εὐτελοῦς ἢ περὶ ταφρείαν τινὰ καὶ χαράκωσιν ἔργου συνεφαπτόμενος. οὐ γὰρ οὕτως τοὺς τιμῆς καὶ χρημάτων μεταδιδόντας, ὡς τοὺς πόνου καὶ κινδύνου μεταλαμβάνοντας ἡγεμόνας θαυμάζουσιν, ἀλλὰ μᾶλλον ἀγαπῶσι τῶν ῥᾳθυμεῖν ἐπιτρεπόντων τοὺς συμπονεῖν ἐθέλοντας.
