   • 'Constantinople adopted the follies, though not the virtues of ancient Rome,' wrote Edward Gibbon, 'and the same factions which had agitated the circus raged with redoubled fury in the Hippodrome.' Gibbon's judgment was that what produced the 'redoubled fury' in the Hippodrome was senseless hooliganism, and even though the Blues and Greens could be politicized upon occasion, they had no coherent aims, religious or political. Gibbon's successors had alternative suggestions, the most persistent of which has been that the Blues were supporters of religious orthodoxy and the Greens of Monophysitism.
