Virgil wrote of an account of the celebrations and where the different animals came from. Augustine also wrote on the subject. you know the games started as a funeral celebration. the idea of the animals was to show man was better than animals. that the animal was at the mercy of Rome just like any living thing in their control
Reply:Animals were imported from the far reaches of the Empire. This activity was usually 'outsourced' to the local natives of the region. The natives were told what was needed and they trapped and caged the beasts for shipment to Rome (and other amphitheaters of the Empire).
Reply:The Romans purchased those animals from traders from Africa and Asia, Romans not only purchase animals but also slaves to be trained as Gladiators together with the criminals.
Reply:Romans did not do the catching themselves they simply traded with African traders to bring the exotic creatures from Africanus (mainly). So it would have been the poor Africans that did the difficult bit, Romans would have used a series of middlemen traders to get the animals to the Beast master at the Coliseum
