The Tiber, too, still remains; but its present appearance has been variously estimated. "The Tiber," says Dr. Burton, "is a stream of which classical recollections are apt to raise too favourable anticipations. When we think of the fleets of the capital of the world sailing up it, and pouring in their treasures of tributary kingdoms, we are likely to attach to it ideas of grandeur and magnificence. But if we come to the Tiber with such expectations, our disappointment will be great."
Sir John Hobhouse speaks differently: "Arrived at the bank of the Tiber," he says, speaking of the traveller's approach to Rome from the north, across the Ponte Molle, "he does not find the muddy insignificant stream, which the disappointments of overheated imaginations have described it; but one of the finest rivers of Europe, now rolling through a vale of gardens, and now sweeping the base of swelling acclivities, clothed with wood, and crowned with villas, and their evergreen shrubberies." Notwithstanding this, the Tiber can be by no means called a large river, and it is scarcely navigable even below Rome, owing to the frequent shoals which impede its course. A steam-boat, which plies between the capital and Fiumicino, a distance of about sixteen miles, is generally five or six hours in making the passage. Ordinary vessels are three days in making their way up the Tiber to Rome; being towed up always by buffaloes. The velocity of its current may be estimated from the fact, that it deposits its coarser gravel thirty miles from the city, and its finer at twelve; it hence pursues its course to the sea, charged only with a fine yellowish sand, imparting to its waters that peculiar colour, which poets call golden, and travellers muddy. Yet these waters enjoyed, at one time, a high reputation for sweetness and salubrious qualities. Pope Paul the Third invariably carried a supply of the water of the Tiber with him on his longest journeys; and his predecessor, Clement the Seventh, was similarly provided, by order of his physician, when he repaired to Marseilles, to celebrate the marriage of his niece, Catherine de Medici, with the brother of the Dauphin, afterwards Henry the Second of France.
