Scriptores Historiae Augustae,  Carus, Carinus, Numerian  19.1-3 (ca. 360 A.D.):

Memorabile maxime Cari et Carini et Numeriani hoc habuit imperium, quod ludos populo Romano novis ornatus spectaculis dederunt, quos in Palatio circa porticum stabuli pictos vidimus. 2. Nam et neurobaten, qui velut in ventis cothurnatus ferretur, exhibuit, et toichobaten, qui per parietem urso eluso cucurrit, et ursos mimum agentes et item centum salpistas uno crepitu concinentes et centum ceratulas, choraulas centum, etiam pythaulas centum, pantomimos et gymnicos mille, pegma praeterea, cuius flammis scaena conflagravit, quam Diocletianus postea magnificentiorem reddidit. Mimos praeterea undique advocavit. 3. Exhibuit et ludum Saramaticum, quo dulcius nihil est. Exhibuit Cyclopea. Donatum est Graecis artificibus et gymnicis et histrionibus et musicis aurum et argentum, donata et vestis serica.

The most noteworthy event of the rule of Carus, Carinus, and Numerian was the series of games that they gave the Roman people, distinguished by some novel spectacles, a painting of which we have seen in the Palace near the portico of the stables. 2. For there was exhibited a rope-walker, who in his buskins seemed to be walking on the winds, also a wall-climber, who, eluding a bear, ran up a wall, also some bears which acted a farce, and, besides, one hundred trumpeters who blew one single blast together, one hundred horn-blowers, one hundred flute-players, also one hundred flute-players who accompanied songs, one thousand pantomimists and gymnasts, moreover, a mechanical scaffold, which, however burst into flames and burned up the stage—though this Diocletian later restored on a more magnificent scale. Furthermore the actors were gathered together from every side. 3. They were given also Sarmatian games, than which nothing affords greater pleasure, and, besides, a Cyclops performance. And they bestowed on the Greek artists and gymnasts and actors and musicians both gold and silver and they bestowed on them also garments of silk. (D. Magie, trans.)
