The two came out from behind the pillar and stood still to listen; and Gambardella's eyes gazed steadily at the vast mosaic above the tribune, while his friend's look fixed itself again on Ortensia's graceful figure, and he feasted his sight, while his ears were filled with the most rare music that the world had ever heard in that day.
Only those who have listened to a beautiful voice singing in the Lateran towards evening can understand that, in spite of the grievous disfigurements of the barocco age, and the exaggerated modern decorations of the nineteenth century, the 'Mother of all Churches,' as the Basilica is called, can still seem the most deeply and truly hallowed place of worship in Christendom. There is a mystery in it at the sunset hour which is felt by all men, though none can explain it; the light glows and fades there as nowhere else, the shadows have a sweet solemnity of their own, and consummate art, or supreme good-fortune, has made the vast nave and colonnaded aisles responsive to the softest notes the human voice can breathe. First the full organ blares out triumphantly alone, and by and by the chorus, borne up by the master instrument, swells from a hundred throats in such tremendous harmonies that the marble pavement seems alive and thrilling under a man's feet; yet the words are not lost in a clashing din of senseless noise, for every one of them is complete and reaches the astonished ear unbroken and distinct. Then, in an instant, the enormous gale of sound is hushed and leaves no echo, and one voice alone is singing a low melody, divinely spiritual as an angel's prayer. It rises presently, full and strong, but every syllable rings out clear and perfect, even to the outer doors; it sinks to all but a whisper, yet each delicate articulation floats unbroken to the remotest corner of the outer aisle, till he who listens feels the word vibrating in his heart rather than in his outward ears.
Ortensia felt more than that, for the music was that of the man she loved so well, and the single voice was his too, and the prayer it sang was for her, and was in her heart while she listened; and, moreover, Alessandro Stradella was not matched in voice or genius by any singer of his age. It would be as hopeless to attempt a description of his singing on that day as to analyse the feelings that thrilled Ortensia. There are delights that must be felt to be believed, and only three are noble, for they have their sources in true love, and in supreme art, and in honourable fight for wife and child and country. Ortensia felt the first two of these together; but he who dies, not having known even one of them, had better not have lived at all.
As afternoon turned to evening, the straight golden beams overhead melted to a red glow that spread downwards and illuminated all the great church for a little while; then the light deepened to purple, and that softened to violet, and the candles about the high altar under the tabernacle shone out through thin clouds of incense like many stars. Again Stradella's voice was heard alone, and Ortensia sank upon her knees beside her pillar, though it was not yet quite time for kneeling. It was as if she could bear no more of such intense pleasure without praying to heaven that it might be hers hereafter to love her true love to all ages, and for ever to hear his voice singing to her in a place of peace.
The Bravi had now parted company, and Trombin had quietly gone out of the church, leaving Gambardella alone. The dark-faced man in black moved slowly and noiselessly as a shadow; he crossed the nave far down by the door, and walked up the outer aisle on the south side, till he could go no farther up for the crowd; then he turned to his right, making his way quietly through the multitude wherever the people were least closely packed, and he emerged at last not far from where Ortensia was kneeling, and with all the appearance of having come out of the thick of the press, which was exactly what he wished her to believe.
She was still kneeling, and Cucurullo was standing beside her, hat in hand. It was now so dark in the body of the Basilica that Stradella could not possibly see any one there, especially as he was dazzled by the many candles that illuminated the upper end of the church.
Gambardella bowed gravely and bent down to speak near Ortensia's ear.
'I have a message from the Maestro for you,' he said, almost in a whisper.
Ortensia had already looked up with a little surprise, which now increased.
'A message?' she repeated. 'We came here together, and he has not left the organ loft since!'
