This work consists of three bridges, or tire of arches, one above another; the first of six, the second of eleven, and the third of thirty-six. The height, comprehending the aqueduct on the top, amounts to 174 feet three inches: the length between the two mountains, which it unites, extends to 723. The order of architecture is the Tuscan, but the symmetry of it is inconceivable. By scooping the bases of the pilasters, of the second tire of arches, they had made a passage for foot-travellers: but though the antients far excelled us in beauty, they certainly fell short of the moderns in point of conveniency. The citizens of Avignon have, in this particular, improved the Roman work with a new bridge, by apposition, constructed on the same plan with that of the lower tire of arches, of which indeed it seems to be a part, affording a broad and commodious passage over the river, to horses and carriages of all kinds. The aqueduct, for the continuance of which this superb work was raised, conveyed a stream of sweet water from the fountain of Eure, near the city of Uzes, and extended near six leagues in length.
In approaching Nismes, you see the ruins of a Roman tower, built on the summit of a hill, which over-looks the city. It seems to have been intended, at first, as a watch, or signal-tower, though, in the sequel, it was used as a fortress: what remains of it, is about ninety feet high; the architecture of the Doric order. I no sooner alighted at the inn, than I was presented with a pamphlet, containing an account of Nismes and its antiquities, which every stranger buys. There are persons too who attend in order to shew the town, and you will always be accosted by some shabby antiquarian, who presents you with medals for sale, assuring you they are genuine antiques, and were dug out of the ruins of the Roman temple and baths. All those fellows are cheats; and they have often laid under contribution raw English travellers, who had more money than discretion. To such they sell the vilest and most common trash: but when they meet with a connoisseur, they produce some medals which are really valuable and curious.
