the whole Roman world; and passed too in character, the religion of the cross, joy in sorrow, liberty in bonds, strength in weakness, proclaiming itself best from the midst of the sufferings which it overcame. Immediately beyond the Arch of Drusus is the Gate of St. Sebastian, the Porta Appia of the Aurelian wall, protected on either side by two semicircular towers, which from their great height and massiveness have a most imposing appearance. They are composed of the beautiful glowing brick of the ancient Roman structures, and rest upon a foundation of white marble blocks, evidently taken from the Temple of Mars, which once stood close by, and at which the armies entering Rome in triumph used to halt. The gateway was greatly injured in the sixth century during the Gothic War, but was repaired by Belisarius; or, as some say, by Narses. The most remarkable incident connected with it since that period was the triumphal entry into the city of Marco Antonio Colonna, after the victory of Lepanto over the Turks and African corsairs in 1571. This famous battle, one of the few great decisive battles of the world, belongs equally to civil and ecclesiastical history, having checked the spread of Mohammedanism in Eastern Europe, and thus altered the fortunes of the Church and the world. The famous Spanish poet Cervantes lost an arm in this battle. The ovation given to Colonna by the Romans in connection with it may be said to be the last of the long series of triumphal processions which entered the Eternal City; and in point of splendour and ceremony it vied with the grandest of them,--prisoners and their families, along with the spoil taken from the enemy, figuring in it as of old. A short distance outside the gate, the viaduct of the railway from Civita Vecchia spans the Appian Way, and brings the ancient "queen of roads" and the modern iron-way into strange contrast,--or rather, I should say, into fitting contact; for there is a resemblance between the great works of ancient and modern engineering skill in their mighty enterprise and boundless command of physical resources, which we do not find in the works of the intermediate ages.
