The crowd there that day would have viewed the spectacle as a crushing defeat of this meek man's Christian religion. But Ignatius understood his death to be a shout of victory. Today a Christian cross stands in the Colosseum of Rome with a plaque that reads, "The amphitheater, one consecrated to triumphs, entertainments, and the impious worship of pagan gods, is now dedicated to the sufferings of the martyrs purified from impious superstitions."”
Hopkins & Beard 2005, стр. 103: "It is likely that Christians were put to death there and that those said to have been martyred 'in Rome' actually died in the Colosseum. But, despite what we are often told, that is only a guess. One of the possible candidates for martyrdom in the Colosseum is St. Ignatius, a bishop of Antioch (in Syria) at the beginning of the second century AD, who was 'condemned to the beasts' at Rome."

Hopkins & Beard 2005, стр. 160: "For most of the Middle Ages and early Renaissance the Colosseum was not so much a monument as a quarry. To describe this activity as 'robbery' is to give the wrong impression. For the most part, there was nothing illegal or unofficial about the removal of this stone."
