But in the courtyard, although the three storeys above the ground-floor rise as high as the clock-tower of the Tuileries, the infinite delicacy of the architecture reveals itself to the rapture of our astonished eyes. This wing of the great building, in which the two queens, Catherine de’ Medici and Mary Stuart, held their sumptuous court, is divided in the centre by a hexagon tower, in the empty well of which winds up a spiral staircase,--a Moorish caprice, designed by giants, made by dwarfs, which gives to this wonderful facade the effect of a dream. The baluster of this staircase forms a spiral connecting itself by a square landing to five of the six sides of the tower, requiring at each landing transversal corbels which are decorated with arabesque carvings without and within. This bewildering creation of ingenious and delicate details, of marvels which give speech to stones, can be compared only to the deeply worked and crowded carving of the Chinese ivories. Stone is made to look like lace-work. The flowers, the figures of men and animals clinging to the structure of the stairway, are multiplied, step by step, until they crown the tower with a key-stone on which the chisels of the art of the sixteenth century have contended against the naive cutters of images who fifty years earlier had carved the key-stones of Louis XII.’s two stairways. However dazzled we may be by these recurring forms of indefatigable labor, we cannot fail to see that money was lacking to Francois I. for Blois, as it was to Louis XIV. for Versailles. More than one figurine lifts its delicate head from a block of rough stone behind it; more than one fantastic flower is merely indicated by chiselled touches on the abandoned stone, though dampness has since laid its blossoms of mouldy greenery upon it. On the facade, side by side with the tracery of one window, another window presents its masses of jagged stone carved only by the hand of time. Here, to the least artistic and the least trained eye, is a ravishing contrast between this frontage, where marvels throng, and the interior frontage of the chateau of Louis XII., which is composed of a ground-floor of arcades of fairy lightness supported by tiny columns resting at their base on a graceful platform, and of two storeys above it, the windows of which are carved with delightful sobriety. Beneath the arcade is a gallery, the walls of which are painted in fresco, the ceiling also being painted; traces can still be found of this magnificence, derived from Italy, and testifying to the expeditions of our kings, to which the principality of Milan then belonged.
