The principal entrance to the picture galleries of the Louvre is in the Pavilion Molière, opposite the square of the Carrousel. After passing a spacious vestibule, where mouldings of Trajan's Column and a fine collection of antique busts may be seen, the visitor ascends a staircase adorned with Etruscan works in terra-cotta and reaches the round hall or cupola of the magnificent Apollo Gallery, decorated with wall paintings and painted ceilings by the courtly Lebrun of Louis XIV.'s time and the vigorous imaginative Eugène Delacroix of our own. What can be more admirable than Delacroix's "Nymph," at whose feet crouches a panther? "Behold this work," writes Théophile Gautier, "and you will see that for colour France has no longer any reason for envying Italy, Flanders, or Spain. Delacroix, in this great page, in which the energy of his talent is freely displayed, shows a knowledge of decorative art which has never been surpassed. Impossible while never departing from his own genius to be more in harmony with the style of the gallery and of the epoch. One might here call him a florid romantic Lebrun." The Apollo Gallery leads to the before-mentioned Salon Carré, where Paul Veronese's "Marriage of Cana" at once attracts attention, not only by its immense proportions, but also and above all by the richness of the colouring and the beauty of the composition. Here, too, is the portrait by Leonardo da Vinci, known in France as "La Joconde"; "a miracle of painting," says Gautier, who has made it the subject of one of his most remarkable criticisms. "'La Joconde,' sphinx of beauty," he exclaims, "smiling so mysteriously in the frame of Leonardo da Vinci, and apparently proposing to the admiration of centuries an enigma which they have not yet solved, an invincible attraction still brings me back towards you. Who, indeed, has not remained for long hours before that head, bathed in the half-tones of twilight, enveloped in transparency; whose features, melodiously drowned in a violet vapour, seem the creation of some dream through the black gauze of sleep? From what planet has fallen in the midst of an azure landscape this strange being whose gaze promises unheard-of delights, whose experience is so divinely ironical? Leonardo impresses on his faces such a stamp of superiority that one feels troubled in their presence. The partial shadow of their deep eyes hides secrets forbidden to the profane; and the inflexions of their mocking lips are worthy of gods who know everything and calmly despise the vulgarities of man. What disturbing fixity, what superhuman sardonicism in these sombre pupils, in these lips undulating like the bow of Love after he has shot his dart. La Joconde would seem to be the Isis of some cryptic religion, who, thinking herself alone, draws aside the folds of her veil, even though the imprudent man who might surprise her should go mad and die. Never did feminine ideal clothe itself in more irresistibly seductive forms.
