“Another, O my God! but stronger.”

The guards, terrified with what they thought the impious ravings of a desperate madman, fled in horror.

After they were gone, as I was pondering the matter over, I found that I looked upon the overthrow of the Doge’s palace as one of the events which might lead to liberty; the mighty pile, as it fell, might throw me safe and sound, and consequently free, on St. Mark’s Place, or at the worst it could only crush me beneath its ruins.  Situated as I was, liberty reckons for all, and life for nothing, or rather for very little.  Thus in the depths of my soul I began to grow mad.

This earthquake shock was the result of those which at the same time destroyed Lisbon.

CHAPTER XXVII

Various Adventures—­My Companions—­I Prepare to Escape—­Change of Cell

To make the reader understand how I managed to escape from a place like the Leads, I must explain the nature of the locality.

The Leads, used for the confinement of state prisoners, are in fact the lofts of the ducal palace, and take their name from the large plates of lead with which the roof is covered.  One can only reach them through the gates of the palace, the prison buildings, or by the bridge of which I have spoken called the Bridge of Sighs.  It is impossible to reach the cells without passing through the hall where the State Inquisitors hold their meetings, and their secretary has the sole charge of the key, which he only gives to the gaoler for a short time in the early morning whilst he is attending to the prisoners.  This is done at day-break, because otherwise the guards as they came and went would be in the way of those who have to do with the Council of Ten, as the Council meets every day in a hall called The Bussola, which the guards have to cross every time they go to the Leads.

The prisons are under the roof on two sides of the palace; three to the west (mine being among the number) and four to the east.  On the west the roof looks into the court of the palace, and on the east straight on to the canal called Rio di Palazzo.  On this side the cells are well lighted, and one can stand up straight, which is not the case in the prison where I was, which was distinguished by the name of ‘Trave’, on account of the enormous beam which deprived me of light.  The floor of my cell was directly over the ceiling of the Inquisitors’ hall, where they commonly met only at night after the sitting of the Council of Ten of which the whole three are members.

As I knew my ground and the habits of the Inquisitors perfectly well, the only way to escape—­the only way at least which I deemed likely to succeed—­was to make a hole in the floor of my cell; but to do this tools must be obtained—­a difficult task in a place where all communication with the outside world was forbidden, where neither letters nor visits were allowed.  To bribe a guard a good deal of
