And behold the result, the witness of the miracle: In the domed sacristy, the fountain cooling this sultry afternoon of June as it has cooled four hundred Junes and more since set up, arch and pilasters and statued gables hung with garlands by that particular Robbia; cooling and refreshing us with its empty trough and closed taps, without a drop of real water! For it is made of water itself, or the essence, the longing memory of water. It is water, this shining pale amber and agate and grass-green tiling and wainscotting, starred at regular intervals by wide-spread patterns as of floating weeds; water which makes the glossiness of the great leaf-garlands and the juiciness of the smooth lemons and cool pears and pomegranates; water which has washed into ineffable freshness this piece of blue heaven within the gable; and water, you would say, as of some shining fountain in the dusk, which has gathered together into the white glistening bodies and draperies which stand out against that newly-washed aether. All this is evident, and yet insufficient to account for our feelings. The subtlest and most potent half of the spell is hidden; and we guess it only little by little. In this little Grecian tabernacle, every line save the bare verticals and horizontals is a line suggestive of trickling and flowing and bubbles; a line suggested by water and water's movement; and every light and shadow is a light or a shadow suggested by water's brightness or transparent gloom; it is water which winds in tiny meanders of pattern along the shallow shining pillars, and water which beads and dimples along the shady cornice. The fountain has been thought out in longing for water, and every detail of it has been touched by the memory thereof. Water! they wanted water, and they should have it. By a coincidence almost, Giovanni della Robbia has revealed the secret which himself most probably never guessed, in the little landscape of lilac and bluish tiles with which he filled up the arch behind the taps. Some Tuscan scene, think you? Hills and a few cypresses, such as his contemporaries used for background? Not a bit. A great lake, an estuary, almost a sea, with sailing ships, a flooded country, such as no Florentine had ever seen with mortal eyes; but such as, in his longing for water, he must have dreamed about. Thus the landscape sums up this dream, this realisation of every cool and trickling sight and touch and sound which fills that sacristy as with a spray of watery thoughts. In this manner, with perhaps but a small effort of invention and a small output of fancy, and without departing in the least from the general proportions and shapes and ornaments common in his day, has an artist of the second order left us one of the most exquisitely shapely and poetical of works, merely by following the suggestions of the use, the place, the religious message and that humble human wish for water where there was none.
