While I was immersed in this toilsome sea of thought, an event happened which brought home to me the sad state of mind I was in.

I was standing up in the garret looking towards the top, and my glance fell on the great beam, not shaking but turning on its right side, and then, by slow and interrupted movement in the opposite direction, turning again and replacing itself in its original position. As I lost my balance at the same time, I knew it was the shock of an earthquake. Lawrence and the guards, who just then came out of my room, said that they too, had felt the earth tremble. In such despair was I that this incident made me feel a joy which I kept to myself, saying nothing. Four or five seconds after the same movement occurred, and I could not refrain from saying,

"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.
