Balista or Ballista (died c. 261), also known in the sources with the name of "Callistus", was one of the Thirty Tyrants of the controversial Historia Augusta, and supported the rebellion of the Macriani[disambiguation needed] against Emperor Gallienus.
Balista was the praetorian prefect under Valerian. After Persians defeated and captured that emperor in the Battle of Edessa, a body of Roman troops was rallied by a fiscal officer, Macrianus, and Balista. Joined by Odaenathus, the Lord of Palmyra, they routed the Persian army that was returning from the ravaging of Cilicia. Then Macrianus proclaimed his sons, Macrinus and Quietus, as emperors.
He stayed with Quietus in the East, while Macrianus and his elder son moved with the army against the West. In the Balkans, Macriani were routed by the commander of Roman cavalry, Aureolus, a general loyal to Gallienus, and killed. Then Gallienus invited Odenathus to turn against his former allies, Ballista and Quietus. Neither the time nor manner of Balista's death can be ascertained with certainty, but it is believed to have happened about November 261, and to have been contrived by Odaenathus. Another suggestion is that they were killed by their own men at Emesa.
