‘Panem et circenses’, said the Romans - ‘Bread and circuses’.
This maxim served the Romans well. In times of crisis and whenever they needed a distraction from military defeats or political infighting at the highest levels, they simply entertained the masses.
Caroline Wazir wrote an article in The Atlantic in 2016, linking entertainment and the need for political validation in the Roman Empire.
“The Exotic Animal Traffickers of Ancient Rome” is a good summation of how thousands of rare animals - at least rare for the Romans - were transported to Rome to be butchered at the Colosseum.
The practice was used in the early years of the Roman Empire to win approval for ambitious emperors and, during the age of decadence, to distract from the failures of struggling Caesars.
Ultimately, the entire exercise had little to do with entertainment for its sake and everything to do with distraction.
