It is partitioned lengthwise, and through one compartment walked such as bore light sentences in ancient times, and through the other marched sadly the wretches whom the Three had doomed to lingering misery and utter oblivion in the dungeons, or to sudden and mysterious death.

Down below the level of the water, by the light of smoking torches, we were shown the damp, thick-walled cells where many a proud patrician's life was eaten away by the long-drawn miseries of solitary imprisonment--without light, air, books; naked, unshaven, uncombed, covered with vermin; his useless tongue forgetting its office, with none to speak to; the days and nights of his life no longer marked, but merged into one eternal eventless night; far away from all cheerful sounds, buried in the silence of a tomb; forgotten by his helpless friends, and his fate a dark mystery to them forever; losing his own memory at last, and knowing no more who he was or how he came there; devouring the loaf of bread and drinking the water that were thrust into the cell by unseen hands, and troubling his worn spirit no more with hopes and fears and doubts and longings to be free; ceasing to scratch vain prayers and complainings on walls where none, not even himself, could see them, and resigning himself to hopeless apathy, driveling childishness, lunacy! Many and many a sorrowful story like this these stony walls could tell if they could but speak.
In a little narrow corridor, near by, they showed us where many a prisoner, after lying in the dungeons until he was forgotten by all save his persecutors, was brought by masked executioners and garroted, or sewed up in a sack, passed through a little window to a boat, at dead of night, and taken to some remote spot and drowned.
They used to show to visitors the implements of torture wherewith the Three were wont to worm secrets out of the accused--villainous machines for crushing thumbs; the stocks where a prisoner sat immovable while water fell drop by drop upon his head till the torture was more than humanity could bear; and a devilish contrivance of steel, which inclosed a prisoner's head like a shell, and crushed it slowly by means of a screw.

It bore the stains of blood that had trickled through its joints long ago, and on one side it had a projection whereon the torturer rested his elbow comfortably and bent down his ear to catch the moanings of the sufferer perishing within.
Of course we went to see the venerable relic of the ancient glory of Venice, with its pavements worn and broken by the passing feet of a thousand years of plebeians and patricians--The Cathedral of St.Mark.
It is built entirely of precious marbles, brought from the Orient -- nothing in its composition is domestic.

Its hoary traditions make it an object of absorbing interest to even the most careless stranger, and thus far it had interest for me; but no further.

I could not go into ecstasies over its coarse mosaics, its unlovely Byzantine architecture, or its five hundred curious interior columns from as many distant quarries.
