Once more the young man found himself alone on the gloomy expanse of the
Piazza of St. Peter's. Not a single belated pedestrian was to be seen.
There was only the lofty, livid, ghost-like obelisk, emerging between its
four candelabra, from the mosaic pavement of red and serpentine porphyry.
The facade of the Basilica also showed vaguely, pale as a vision, whilst
from it on either side like a pair of giant arms stretched the quadruple

desire, and he was now stupefied to find that he had done so.

But sudden despair seized upon him, such atrocious distress of spirit
that, from the depths of the abyss of darkness where he stood, he raised
