To pass from the Baptistery into the Campo Santo, where among Christian graves the cypresses are dying in the earth of Calvary, and the urns and sarcophagi of pagan days hold Christian dust, is perhaps to make easier the explanation we need of the art of Niccolo. Here, it is said, he often wandered "among the many spoils of marbles brought by the armaments of Pisa to this city." Among these ancient sarcophagi there is one where you may find the Chase of Meleager and the Calydonian boar; this was placed by the Pisans in the facade of the Duomo opposite S. Rocco, and was used as a tomb for the Contessa Beatrice, the mother of the great Contessa Matilda. Was it while wandering here, in looking so often on that tomb on his way to Mass, that he was moved by its beauty till his heart remembered its childhood in a whole world of such things? It must have been so, for here all things meet together and are reconciled in death. Out of the dust and heat of the Piazza one comes into a cool cloister that surrounds a quadrangle open to the sky, in which a cypress still lives. The sun fills the garden with a golden beauty, in which the butterflies flit from flower to flower over the dead. I do not know a place more silent or more beautiful. One lingers in the cool shadow of the cloisters before many an old marble,--a vase carved with Bacchanalian women, the head of Achilles, or the bust of Isotta of Rimini. But it is before the fresco of the Triumph of Death that one stays longest, trying to understand the dainty treatment of so horrible a subject. Those fair ladies riding on horseback with so brave a show of cavaliers, even they too must come at last to be just dust, is it, or like that swollen body, which seems to taint even the summer sunshine, lying there by the wayside, and come upon so unexpectedly? What love-song was that troubadour, fluttering with ribbons, singing to that little company under the orange-trees, cavaliers and ladies returned from the chase, or whiling away a summer afternoon playing with their falcons and their dogs? The servants have spread rich carpets for their feet, and into the picture trips a singing girl, who has surely called the very loves from Paradise or from the apple-trees covered with blossom, where they make their temporary abode. What love song were they singing, ere the music was frozen on their lips by a falling leaf or chance flutter of bird life calling them to turn, and lo, Death is here?
