I delivered my passport at the door of the palace, and, as is customary, recorded my name, country, and profession in the book, and proceeded to the gallery. The grand double staircase, one part leading to the private apartments of the royal household, is described voluminously in the authorities; and, truly, for one who has been accustomed to convenient dimensions only, its breadth, its lofty ceilings, its pillars and statuary, its mosaic pavements and splendid windows, are enough to unsettle for ever the standards of size and grandeur. The strongest feeling one has, as he stops half way up to look about him, is the ludicrous disproportion between it and the size of the inhabiting animals. I should smile to see any man ascend such a staircase, except, perhaps, Napoleon. Passing through a kind of entrance-hall, I came to a spacious _salle ronde_, lighted from the ceiling, and hung principally with pictures of a large size, one of the most conspicuous of which, "The Wreck," has been copied by an American artist, Mr. Cooke, and is now exhibiting in New York. It is one of the best of the French school, and very powerfully conceived. I regret, however, that he did not prefer the wonderfully fine piece opposite, which is worth all the pictures ever painted in France, "The Marriage Supper at Cana." The left wing of the table, projected toward the spectator, with seven or eight guests who occupy it, absolutely stands out into the hall. It seems impossible that color and drawing upon a flat surface can so cheat the eye. From the _salle ronde_, on the right opens the grand gallery, which, after the lesson I had just received in perspective, I took, at the first glance, to be a painting. You will realize the facility of the deception when you consider, that, with a breadth of but forty-two feet, this gallery is one thousand three hundred and thirty-two feet (more than a quarter of a mile) in length. The floor is of tesselated woods, polished with wax like a table; and along its glassy surface were scattered perhaps a hundred visiters, gazing at the pictures in varied attitudes, and with sizes reduced in proportion to their distance, the farthest off looking, in the long perspective, like pigmies of the most diminutive description. It is like a matchless painting to the eye, after all. The ceiling is divided by nine or ten arches, standing each on four Corinthian columns, projecting into the area; and the natural perspective of these, and the artists scattered from one end to the other, copying silently at their easels, and a soldier at every division, standing upon his guard, quite as silent and motionless, would make it difficult to convince a spectator, who was led blindfold and unprepared to the entrance, that it was not some superb diorama, figures and all.
