Colosseum [SEP] Significance in Christianity
The Colosseum is generally regarded by Christians as a site of the martyrdom of large numbers of believers during the persecution of Christians in the Roman Empire, as evidenced by Church history and tradition. On the other hand, other scholars believe that the majority of martyrdoms may have occurred at other venues within the city of Rome, rather than at the Colosseum, citing a lack of still-intact physical evidence or historical records. These scholars assert that "some Christians were executed as common criminals in the Colosseum—their crime being refusal to reverence the Roman gods", but most Christian martyrs of the early Church were executed for their faith at the Circus Maximus.
