Those will enjoy Rome most who have studied it thoroughly before leaving their own homes. In the multiplicity of engagements in which a foreigner is soon involved, there is little time for historical research, and few are able to do more than "read up their Murray," so that half the pleasure and all the advantage of a visit to Rome are thrown away: while those who arrive with the foundation already prepared, easily and naturally acquire, amid the scenes around which the history of the world revolved, an amount of information which will be astonishing even to themselves. "People out of Rome," says Goethe, "have no idea how one is _schooled_ there;" but then, as the author of 'Vera' remarks, "that is true of Rome, which Madame Swetchine said of life, viz. that you find exactly what you put into it." The pagan monuments of Rome have been written of and discussed ever since they were built, and the catacombs have lately found historians and guides both able and willing,--about the later Christian monuments far less has hitherto been said. In English, except in the immense collection of interest which is imbedded in the works of Hemans, and in the few beautiful notices of some of the early martyrs by Mrs. Jameson, very little has been written; in French there is far more. There is a natural shrinking in the English Protestant mind from all that is connected with the story of the saints,--especially the later saints of the Roman Catholic Church. Many believe, with Addison, "that the Christian antiquities are so embroiled in fable and legend, that one derives but little satisfaction from searching into them." And yet, as Mrs. Jameson observes, when all that the controversialist can desire is taken away from the reminiscences of those, who to the Roman Catholic mind have consecrated the homes of their earthly life, how much remains!--"so much to awaken, to elevate, to touch the heart;--so much that will not fade from the memory, so much that may make a part of our after-life." No attempt has been made in these pages to describe the country round Rome, beyond a few of the most ordinary drives and excursions outside the walls. The opening of the railways to Naples and Civita Vecchia have now brought a vast variety of new excursions within the range of a day's expedition--and the papal citadel of Anagni, the temples of Cori, the cyclopean remains of Segni, Alatri, Norba, Cervetri, and Corneto, and the wild heights of Soracte, will probably ere long become as well known as the oft-visited Tivoli, Ostia, and Albano. It is intended to supplement these "Walks in Rome" by a similar volume of "Excursions round Rome." CHAPTER I. DULL-USEFUL INFORMATION.
