The part of the triumphal road was discovered by accident in digging for a drain; and an attempt is being made to procure the permission of the Government to excavate all that can be found of it, and ascertain its exact course. It was in the Temple of Concord that Cicero assembled the Senate and pronounced one of his orations against Catiline. The building must have been large and magnificent, from the remains now visible, which are of the finest marble. The pavement is in a state of considerable preservation. Then we went to the old Tabularium, standing on the Intermontium, an undoubted work of the Republic. This was the place where the records of the Senate were kept. It is very perfect. Nibby, the great authority here, differs, however, about this place; the antiquaries are at daggers drawn upon the subject of the ruins, remains, and discoveries. They have all different systems, which they support with great vehemence and obstinacy, and perhaps ingenuity, but the ignorant and curious traveller is only perplexed with their noisy and discordant assertions. They will insist upon knowing everything, whereas there are many things here which are so doubtful, that they can only conjecture about them; but when once they have published a theory they will not hear of its being erroneous, and oppose any fresh discovery likely to throw discredit upon it. After his lecture in the Forum we went to San Nicolo in Cercera, an old church built on three old temples, or two and a prison, but not much to see. The prison of San Nicolo in Cercera is said to be the scene of the story of the Roman daughter, which it probably is not. Over the Bridge of Fabricius to the Basilica of Saint Bartholomew and Temple of Esculapius; small remains, but curious; and very pretty view of the Tiber and Temple of Vesta. To the Villa Lanti, a delicious villa belonging to Prince Borghese, who never goes there, and will neither let nor lend it. One of the finest views of Rome is from the terrace, and Julio Romano's frescoes adorn the ceilings. When Raphael was painting the Vatican, he and Julio Romano used to retire every night to the Villa Lanti, and the ceilings are covered with frescoes painted by both of them. Just below is a terrace, and on it a beautiful tree called Tasso's Oak, because under it he used to sit and compose when he lived in the Convent of San Onofrio, which is close by, and where he died. This convent is remarkably clean, airy, and spacious. In the library is a bust of Tasso, a mask taken from his face just after he died; in the chapel his tomb. And Tasso is their glory-- Hark to his strain and then survey his cell. BYRON.
