Plutarch, Titus Flamininus
Bernadotte Perrin, Ed.

16. But the hardest toils and struggles fell to Titus when he interceded with Manius in behalf of the Chalcidians. They had incurred the consul's wrath because of the marriage which Antiochus had made in their city after the war had already begun, a marriage which was not only unseasonable, but unsuitable for the king's years, since he was an elderly man and had fallen in love with a girl (the girl was a daughter of Cleoptolemus, and is said to have been most beautiful among maidens).¹ [2] This marriage induced the Chalcidians to take the king's side most zealously and allow their city to be his base of operations for the war. Antiochus, therefore, fleeing with all speed after the battle at Thermopylae, came to Chalcis, and taking with him his girl-wife, his treasure, and his friends, sailed back to Asia; but Manius immediately marched against Chalcis in a rage. He was accompanied, however, by Titus, who tried to mollify and intercede with him and at last won him over and calmed him down by entreaties addressed both to him and the other Romans in authority.

[3] Having been thus saved by Titus, the Chalcidians dedicated to him the largest and most beautiful of the votive offerings in their city, and on them such inscriptions as these are still to be seen: ‘This gymnasium is dedicated by the people to Titus and Heracles,’ and again in another place, ‘This Delphinium is dedicated by the people to Titus and Apollo.’ [4] Moreover, even down to our own day a priest of Titus is duly elected and appointed, and after sacrifice and libations in his honour, a set hymn of praise to him is sung: it is too long to be quoted entire, and so I will give only the closing words of the song:

And the Roman faith we revere, which we have solemnly vowed to cherish; sing, then, ye maidens, to great Zeus, to Rome, to Titus, and to the Roman faith: hail, Paean Apollo! hail, Titus our saviour!
