Bonus (Greek: Βῶνος or Βόνος), also Bonos or Bonosus, was a Byzantine general, active in the reign of Justin II (r. 565–578).
In 569/570, Tiberius II Constantine, the comes excubitorum, instructed Bonus to guard the river crossings of the Danube once more.
[1] The 10th-century Suda lexicon preserves another fragment of Menander Protector concerning Bonus, though its context is left unclear.
The passage has Bonus warning his men that the Avars use battle cries and the beating of the drums to unnerve their enemies.
Since Bonos knew this in advance, he forewarned the soldiers, so that they would not be dumbfounded by the melee, but imitating in advance what was going to happen, to be accustomed to what was to come by the similarity even before the event, and when they perceived the beating of the drums, they themselves would beat in return with their shields and shout the war-song and sing a paean and make a thump on the water-pots (which were made of wood)."
