Laudator Temporis Acti

Livy 21.2.6 (on Hasdrubal; tr. B.O. Foster):

But peace brought him no security. A barbarian whose master he had put to death murdered him in broad daylight, and when seized by the bystanders he looked as happy as though he had escaped. Even when put to the torture, his delight at the success of his attempt mastered his pain and his face wore a smiling expression.

ceterum nihilo ei pax tutior fuit; barbarus eum quidam palam ob iram interfecti ab eo domini obtruncavit; comprensusque ab circumstantibus haud alio quam si evasisset vultu tormentis quoque cum laceraretur, eo fuit habitu oris ut superante laetitia dolores ridentis etiam speciem praebuerit.

Valerius Maximum 3.3 ext 7 (tr. D.R. Shackleton Bailey):

A barbarian slave, angry with Hasdrubal because he had killed his master, suddenly attacked and slew him. Apprehended, he suffered all manner of torments, but resolutely maintained upon his face the joy his vengeance had given him.

servus barbarus Hasdrubalem, quod dominum suum occidisset graviter ferens, subito adgressus interemit, cumque comprehensus omni modo cruciaretur, laetitiam tamen, quam ex vindicta ceperat, in ore constantissime retinuit.
