[CHAPTER XI]
THE BLACK MASS
The night was sultry and dismal.
Dense black clouds rolled over the Roman Campagna, burning blue in the flashes of jagged lightnings and the low boom of distant thunder reverberated ominously among the hills and valleys of Rome, when three men, cloaked and wearing black velvet masks, skirted the huge mediæval wall with which Pope Leo IV had girdled the gardens of the Vatican and, passing along the fortified rampart which surrounded the Vatican Hill, plunged into the trackless midnight gloom of deep, branch-shadowed thickets.
Not a word was spoken between them. Silently they followed their leader, whose tall, dark form was revealed to them only among the dense network of trees and the fantastic shapes of the underbrush, when a flash of white lightning flamed across the limitless depths of the midnight horizon.
Not a sound broke the stillness, save the menacing growl of the thunder, the intermittent soughing of the wind among the branches, or the occasional drip-drip of dewy moisture trickling tearfully from the leaves, mingling with the dreamy, gurgling sound of the fountains, concealed among bosquets of orange and almond trees.
From time to time, as they proceeded upon their nocturnal errand, the sounds of their footsteps being swallowed up by the soft carpet of moss, they caught fleet glimpses of marble statues, gleaming white, like ghosts, from among the tall dark cypresses, or the shimmering surface of a marble-cinctured lake, mirrored in the sheen of the lightnings.
The grove they traversed assumed by degrees the character of a tropical forest. Untrodden by human feet, it seemed as though nature, grown tired of the iridescent floral beauty of the environing gardens, had, in a sudden malevolent mood, torn and blurred the fair green frondage and twisted every bud awry, till the awkward, misshapen limbs resembled the contorted branches of wind-blown trees. Great jagged leaves covered with prickles and stained with blotches as of spilt poison, thick brown stems, glistening with slimy moisture and coiled up like the sleeping bodies of snakes, masses of blue and purple fungi, and blossoms seemingly of the orchid-species, some like fleshly tongues, others like the waxen yellow fingers of a dead hand, protruded spectrally through the matted foliage, while all manner of strange overpowering odors increased the swooning oppressiveness of the sultry, languorous air.
Arrived at a clearing they paused.
In the distance the Basilica of Constantine was sunk in deep repose. All about them was the pagan world. Goat-footed Pan seemed to peer through the interstices of the branches. The fountains crooned in their marble basins. Centaurs and Bacchantes disported themselves among the flowering shrubs and, dark against the darker background of the night, the vast ramparts of Leo IV seemed to shut out light and life together.
