The floor is very beautiful, and there is a faded series of saints by one of the Vivarini of Murano, behind the altar, on which the eye rests very comfortably--chiefly perhaps on the panels which are only painted curtains; but the most memorable feature of the cathedral is the ancient Byzantine mosaic of the Madonna--a Greek Madonna--in the hollow of the apse: a long slender figure in blue against a gold background who holds her hands rather in protest than welcome, and is fascinating rather for the piety which set her there with such care and thought to her glory than for her beauty. Signor Rooskin, it is true, saw her as a symbol of sadness, and some of the most exquisite sentences of "The Stones of Venice" belong to her; but had her robe been of less lovely hues it is possible that he might have written differently. When the church was built, probably in the tenth century, the Virgin was its patron saint. S. Donato's body being brought hither by Doge Domenico Michiel (1118-1130), the church was known as Santa Maria, or San Donato; and to-day it is called S. Donato. And when the time comes for the old sacristan to die, I hope (no matter what kind of a muddle his life has been) that S. Donato will be at hand, near the gate, to pull him through, for sheer faithfulness to his church. The gondola returns by the same route, and as we pass the Campo Santo the rays of the afternoon sun seem so to saturate its ruddy walls that they give out light of their own. It is in order to pass slowly beneath these walls and cypresses that I recommend the gondola as the medium for a visit to Murano. But the penny steamers go to a pier close to S. Donato and are frequent. Murano is within every visitor's range, no matter how brief his stay, but Burano is another matter. The steamer which sails from the pier opposite Danieli's on all fine afternoons except Sundays and holidays requires four hours; but if the day be fine they are four hours not to be forgotten. The way out is round the green island of S. Elena, skirting the Arsenal, the vastness of which is apparent from the water, and under the north wall of Murano, where its pleasant gardens spread, once so gay with the Venetian aristocracy but now the property of market gardeners and lizards. Then through the channels among the shallows, north, towards the two tall minarets in the distance, the one of Burano, the other of Torcello. Far away may be seen the Tyrolean Alps, with, if it is spring, their snow-clad peaks poised in the air; nearer, between us and the islands, is a military or naval station, and here and there yellow and red sail which we are to catch and pass. Venice has nothing more beautiful than her coloured sails, both upon the water and reflected in it.
