more or less disposed to believe in the oracle of which he makes choice.

I then was in this state of mind; but not knowing how to make use of the
Bible to inform me of the moment in which I should recover my liberty, I
determined to consult the divine Orlando Furioso, which I had read a
hundred times, which I knew by heart, and which was my delight under the
Leads. I idolized the genius of Ariosto, and considered him a far better
fortune-teller than Virgil.

With this idea I wrote a question addressed to the supposed Intelligence,
in which I ask in what canto of Ariosto I should find the day of my
deliverance. I then made a reversed pyramid composed of the number formed
from the words of the question, and by subtracting the number nine I
obtained, finally, nine. This told me that I should find my fate in the
ninth canto. I followed the same method to find out the exact stanza and
verse, and got seven for the stanza and one for the verse.

I took up the poem, and my heart beating as if I trusted wholly in the
oracle, I opened it, turned down the leaf, and read;

'Fra il fin d'ottobre, a il capo di novembre'.

The precision of the line and its appropriateness to my circumstances
appeared so wonderful to me, that I will not confess that I placed my
faith entirely in it; but the reader will pardon me if I say that I did
all in my power to make the prediction a correct one. The most singular
circumstance is that between the end of October and the beginning of
November, there is only the instant midnight, and it was just as the
clock was striking midnight on the 31st of October that I escaped from my
cell, as the reader will soon see.
