The Maison Carree is a beautiful bijou, better known than any other of the curiosities of Nismes. I believe the opinion of Mons. Seguier (formed from a laborious examination of the nail-holes belonging to its last bronze inscription) is generally adopted; viz. that it was a temple dedicated to Caius and Lucius Caesar, grandsons of Augustus. A perfect copy of it, built from actual measurement, may be found in the Temple of Victory and Concord, in the Duke of Buckingham's gardens at Stowe. So admirable is the preservation of the original in every part, owing to the dry and pure air of Languedoc, as almost to operate as a disadvantage. Its freshness and compactness suggest rather too much the idea of a modern pavilion of twenty or thirty years standing, instead of that of a temple; and if I may venture to say so, the same want of the aerugo of age, which renders it more valuable as an architectural relic, produces an incongruous and unpoetical effect on the imagination. Age, in fact, has its own characteristic branch of beauty. An old man with curly hair and a fresh smooth complexion, like Godwin's Struldbrugg, St. Leon, would be an unpleasant and unnatural object. There is a masculine and imposing medium between youthful vigour and decay, in which the leading features of the former man may be distinctly traced; as in Wordsworth's beautiful description of the old knight of Rylstone, and Sir Walter Scott's fine portraiture of Archibald Bell-the-Cat: and I think the analogy holds good in classical remains. Somewhat should be decayed for effect's sake; and those parts only left which are strikingly beautiful, or of a leading and important nature. The Arena, which we next visited, is perhaps more consonant to this standard than the Maison Carree. Its structure is similar to that of the Colosseum at Rome, of which, however, it falls infinitely short in size and grandeur, while at the same time it so far exceeds it in perfectness, as to give a complete idea to an inexperienced eye of its original figure and arrangement, and of the admirable system of accommodation which such places possessed. It has just enough of the graceful decay of age to render it picturesque, and enough of freshness to answer the questions of the antiquarian: and neither too much nor too little is left to the imagination. Mr. Albanis Beaumont, in his work on the Maritime Alps, calculates the number of persons which this building must have held at 16,599, and the spectators in the Colosseum at 34,000. He also states the widest interior circumference of the Arena, as 1110-1/2 feet. The plate engraved in his work, dated 1795, represents two square towers over the principal entrance, erected perhaps by Charles Martel, when he converted the building into a citadel; they have however been since destroyed, and the work of clearing away the houses which defaced both its inside and outside, commenced originally by Louis XVI., has been completed.
