Some days later he wrote to Cattaneo : " I have here
much more need of the exorcist than of the physician,
for my trouble is caused by magic art. I will tell you
about my goblin. The little thief has robbed me of
many crowns ; he puts all my books upside down, opens
my chests, hides my keys, so that I do not know how to
protect myself against him. I am always unhappy, but
especially at night, and I do not know if my trouble
should be attributed to frenzy." In another letter :
**When I am awake I seem to see lights sparkling in
the air ; sometimes my eyes are inflamed so that I fear I
may lose my sight. At other times I hear horrible
noises, hissings, and tinklings, the sound of bells, and,
as it were, clocks all striking the hour at the same time.
