Spite of the peril of her position, and of the terror which still fixed her speechless and crouching on the ground, the effect on Antonina of the strange mingled music of the running water and the bells was powerful enough, when she first heard it, to suspend all her other emotions in a momentary wonder and doubt. She withdrew her hands from her face, and glanced round mechanically to the doorway, as if she imagined that the sounds proceeded from the street.
When she looked, the declining sun, gliding between two of the outer pillars which surrounded the temple, covered with a bright glow the smooth pavement before the entrance. A swarm of insects flew drowsily round and round in the warm mellow light; their faint monotonous humming deepened, rather than interrupted, the perfect silence prevailing over all things without.
But a change was soon destined to appear in the repose of the quiet, vacant scene; hardly a minute had elapsed while Antonina still looked on it before she saw stealing over the sunny pavement a dark shadow, the same shadow that she had last beheld when she stopped in her flight to look behind her in the empty street. At first it slowly grew and lengthened, then it remained stationary, then it receded and vanished as gradually as it had advanced, and then the girl heard, or fancied that she heard, a faint sound of footsteps, retiring along the lateral colonnades towards the river side of the building.
A low cry of horror burst from her lips as she sank back towards her father; but it was unheeded. The voice of Ulpius had resumed in the interval its hollow loudness of tone; he had raised Numerian from the ground; his strong, cold grasp, which seemed to penetrate to the old man’s heart, which held him motionless and helpless as if by a fatal spell, was on his arm.
‘Hear it! hear it!’ cried the Pagan, waving his disengaged hand as if he were addressing a vast concourse of people–‘I advance this man to be one of the servants of the high priest! He has travelled from a far country to the sacred shrine; he is docile and obedient before the altar of the gods; the lost is cast for his future life; his dwelling shall be in the temple to the day of his death! He shall minister before me in white robes, and swing the smoking censer, and slay the sacrifice at my feet!’
He stopped. A dark and sinister expression appeared in his eyes as the word ‘sacrifice’ passed his lips; he muttered doubtingly to himself–‘The sacrifice!–is it yet the hour of the sacrifice?’–and looked round towards the doorway.
The sun still shone gaily on the outer pavement; the insects still circled slowly in the mellow light; no shadow was now visible; no distant footsteps were heard; there was nothing audible but the happy music of the bubbling water, and the chiming, silvery bells.
For a few moments the madman looked out anxiously towards the street, without uttering a word or moving a muscle. The raving fit was nearly possessing him again, as the thought of the sacrifice flashed over his darkened mind; but once more its approach was delayed.
He slowly turned his head in the direction of the interior of the temple. ‘The sun is still bright in the outer courts,’ he murmured in an undertone, ‘the hour of the sacrifice is not yet! Come!’ he continued in a louder voice, shaking Numerian by the arm. ‘It is time that the servant of the temple should behold the place of the sacrifice, and sharpen the knife for the victim before sunset! Arouse thee, bondman, and follow me!’
As yet, Numerian had neither spoken, nor attempted to escape. The preceding events, though some space has been occupied in describing them, passed in so short a period of time, that he had not hitherto recovered from the first overwhelming shock of the meeting with Ulpius. But now, awed though he still was, he felt that the moment of the struggle for freedom had arrived.
‘Leave me, and let us depart!–there can be no fellowship between us again!’ he exclaimed with the reckless courage of despair, taking the hand of Antonina, and striving to free himself from the madman’s grasp. But the effort was vain; Ulpius tightened his hold and laughed in triumph. ‘What! the servant of the temple is in terror of the high priest, and shrinks from walking in the place of the sacrifice!’ he cried. ‘Fear not, bondman! The mighty one, who rules over life and death, and time and futurity, deals kindly with the servant of his choice! Onward! onward! to the place of darkness and doom, where I alone am omnipotent, and all others are creatures who tremble and obey! To thy lesson, learner! by sunset the victim must be crowned!’
He looked round on Numerian for an instant, as he prepared to drag him forward, and their eyes met. In the fierce command of his action, and the savage exultation of his glance, the father saw repeated in a wilder form the very attitude and expression which he had beheld in the Pagan on the morning of the loss of his child. All the circumstances of that miserable hour–the vacant bed-chamber–the banished daughter–the triumph of the betrayer–the anguish of the betrayed–rushed over his mind, and rose up before it vivid as a pictured scene before his eyes.
He struggled no more; the powers of resistance in mind and body were crushed alike. He made an effort to remove Antonina from his side, as if, in forgetfulness of the hidden enemy without, he designed to urge her flight through the open door, while the madman’s attention was yet distracted from her. But, beyond this last exertion of the strong instinct of paternal love, every other active emotion seemed dead within him.
Vainly had he striven to disentangle the child from the fate that might be in store for the parent. To her the dread of the dark shadow on the pavement was superior to all other apprehensions. She now clung more closely to her father, and tightened her clasp round his hand. So, when the Pagan advanced into the interior of the temple, it was not Numerian alone who followed him to the place of sacrifice, but Antonina as well.
They moved to the back of the pile of idols. Behind it appeared a high partition of gilt and inlaid wood reaching to the ceiling, and separating the outer from the inner part of the temple. A low archway passage, protected by carved gates similar to those at the front of the building, had been formed in the partition, and through this Ulpius and his prisoners now passed into the recess beyond.
This apartment was considerably smaller than the first hall of the temple which they had just left. The ceiling and the floor both sloped downwards together, and here the rippling of the waters of the Tiber was more distinctly audible to them than in the outer division of the building. At the moment when they entered it the place was very dark; the pile of idols intercepted even the little light that could have been admitted through its narrow entrance; but the dense obscurity was soon dissipated. Dragging Numerian after him to the left side of the recess, Ulpius drew back a sort of wooden shutter, and a vivid ray of sunlight immediately streamed in through a small circular opening pierced in this part of the temple.
Then there became apparent, at the lower end of the apartment, a vast yawning cavity in the wall, high enough to admit a man without stooping, but running downwards almost perpendicularly to some lower region which it was impossible to see, for no light shot upwards from this precipitous artificial abyss, in the darkness of which the eye was lost after it had penetrated to the distance of a few feet only from the opening. At the base of the confined space thus visible appeared the commencement of a flight of steps, evidently leading far downwards into the cavity. On the abruptly sloping walls, which bounded it on all sides, were painted, in the brilliant hues of ancient fresco, representations of the deities of the mythology–all in the attitude of descending into the vault, and all followed by figures of nymphs bearing wreaths of flowers, beautiful birds, and other similar adjuncts of the votive ceremonies of Paganism. The repulsive contrast between the bright colours and graceful forms presented by the frescoes, and the perilous and gloomy appearance of the cavity which they decorated, increased remarkably the startling significance in the character of the whole structure. Its past evil uses seemed ineradicably written over every part of it, as past crime and torment remain ineradicably written on the human face; the mind imbibed from it terrifying ideas of deadly treachery, of secret atrocities, of frightful refinements of torture, which no uninitiated eye had ever beheld, and no human resolution had ever been powerful enough to resist.
