"Our help is in the name of the Lord, who hath made heaven and earth," sing the Chapter and monks, while Scarpia continues his musings as to the business he has on hand. From the mere catching of the escaped prisoners his thoughts turn to lustful possession of Tosca; and the whole scene, finely contrasted, is worked up with superb force into one of those magnificently solid finales which reveal the technic of Puccini so emphatically. The cannon continue to go off—the sound is managed, by the way, by striking a huge cone over which is stretched, drum-fashion, a tight skin—the whole crowd turn towards the high altar, the stately "Te Deum" swells through the church, and at the end, Scarpia, after saying that for Tosca he would renounce his hopes of heaven, joins in the last phrase: "All the earth shall worship Thee, the Father everlasting." The curtain descends quickly to the harsh progression of chords forming the Scarpia theme.
The second act shows us Scarpia's room in the Farnese Palace. It is on an upper floor. To the left a table is laid, and at the back a large window looks over the courtyard.
Scarpia is at supper, and looks at his watch from time to time impatiently. "Tosca is a famous decoy," he sings; "to-morrow's sunrise shall see the two conspirators hanging side by side on my tallest gallows." Ringing a handbell, which is answered by Sciarrone, he inquires whether Tosca is in the Palace, and learns that she has been summoned thither. Scarpia orders the window to be thrown open, and borne on the evening air comes the sound of a gavotte from the orchestra which is playing in one of the lower rooms at an entertainment given by Queen Caroline. Very skilfully is this graceful little melody, just sufficiently archaic in its mould to be characteristic of the period, used as a background for the clever dialogue which follows, from which we learn that Tosca is to be lured to the Palace in the hope of seeing Cavaradossi. Spoletta comes in to give an account of his visit to the villa, and enrages Scarpia by telling him of Angelotti's escape. The minister is somewhat mollified when Spoletta tells him that he promptly secured the painter. Now, with striking effect, the dance measure gives place to a cantata, proving that Tosca is in the Palace in the Queen's apartments. Scarpia's directions as to securing Cavaradossi are worked into the musical fabric with consummate effect, and continue as the painter, now a prisoner, is led in. Cavaradossi breaks off from his curt and guarded replies to Scarpia's questioning on hearing Tosca's voice. He denies strenuously that Angelotti received any aid from him, and even laughs at his examiner. Scarpia shuts the window in anger, and the repetition of his characteristic similar phrase leads up to a strenuous passage in which determination is skilfully depicted in contrast to the almost colloquial movement of the preceding passages. "Once more," says Scarpia, "where is Angelotti?" and from a remark by Spoletta the application of the process torture to wring a confession from the prisoner is hinted at. Tosca now enters, and runs quickly to her lover, who tells her quickly in an undertone not to say a word of what she has seen at the villa. As Scarpia signals to Sciarrone to slide back the panel which leads to the torture chamber, he says formally, "Mario Cavaradossi, the judge is wanting to take your depositions." Sciarrone then gives the directions to Roberto, an underling, to at first apply the usual pressure, and to increase it as he will direct him.
Then follows a highly dramatic scene, ushered in with a characteristic theme indicating the torture which Tosca's lover is to undergo, between Scarpia and Tosca, in which the latter dismisses the fan episode as a feeble trick to rouse her jealousy. Scarpia, however, comes very quickly to plain speaking, and tells Tosca that she had better confess all that she knows as to the escape of Angelotti if she wishes to spare Cavaradossi an hour of anguish. Tosca learns with horror that a fillet of steel, gradually tightening round the temples, is being applied to Cavaradossi's head, and on hearing his groan of pain, she relents and bursts out that she will speak if he is released. But Mario from within calls on Tosca to be silent, and that he despises the pain. Scarpia directs further pressure to be applied. Tosca is allowed to gaze through the open door, and, distracted by what she sees, signifies her intention of revealing all she knows. Her mind is made up when she hears another groan of anguish, and she tells Scarpia that Angelotti is to be found in the well in the garden of the villa. Scarpia now orders Cavaradossi to be brought in. From Scarpia's directions to Spoletta, the fainting victim, nearly at his last gasp by what he had endured, learns of Tosca's treachery, and curses her. This painful scene, finely worked up as it is in intensity, comes to a climax by the news brought in by Sciarrone of the victory at Marengo by Bonaparte. This enrages Scarpia, but he will at least keep the victim he has in hand; and Cavaradossi, exulting as he foresees the downfall of the minister, is borne off. Tosca now turns to Scarpia, and implores him to save Cavaradossi. Splendidly dramatic is the closing scene, beginning with Scarpia's light and airy remark that his little supper was interrupted, and rising to heights of emotional fulness when Tosca asks him outright to name his price for saving her lover's life. Tosca's horrified scream, to a rising passage of two high notes, when she listens to Scarpia's lascivious proposals, thoroughly fits the situation. The drums are used cleverly to indicate the march of the prisoners to their doom, and the setting up of the gallows for Cavaradossi, and in contrast to Scarpia's sinister passages, comes the broad lyrical and impassioned prayer of Tosca, who rails at God for having forsaken her in her hour of need. Scarpia presses his infamous proposals, when Spoletta returns, and speaking outside brings the news that Angelotti has poisoned himself rather than allow himself to be taken. A question as to the disposal of Cavaradossi brings the climax, and Tosca, by taking upon herself to give directions as to this, indicates her consent to Scarpia's wishes. But this master of deceit will not allow the release to be managed in any but his own way. He tells Spoletta that there will be an execution, but it will be a sham one, as in the case of another prisoner, by name Palmieri, the guns being loaded with blank cartridge only, and the victim instructed to fall and feign death. But Tosca wants more than this on her side of the bargain. Scarpia must give them both a passport out of the place, and as he goes to the table to write it Tosca's eyes catch sight of a knife on the table. In an instant her mind is made up, and as he returns to give her the paper, and to clasp her in a feverish embrace, she plunges the knife into his heart. The death-scene is perhaps a little prolonged, but seeing that it has been preceded by the torturing of Cavaradossi, it is at least logical that Tosca should remind him of the ghastly torture he inflicted on her loved one. The intensity of the scene is rounded off by the expressive phrase on a low monotone of Tosca, "And yesterday all Rome lay at this man's feet." The action to the finishing notes of this moving scene follows that of the play. Tosca searches for the passport, and snatches it from the fast locking palms of the dead man. With a shudder she rinses her finger with a serviette dipped in the carafe, and then puts the candles from the supper table at the head of the corpse, and taking a crucifix from the wall, places it on the breast, as the Scarpia theme in long-drawn chords is played softly by the orchestra. She goes out quietly as the curtain falls.
The third act takes place on an open space or platform within the Castle of S. Angelo. At the back we see the dome of S. Peter's and the Vatican. The expressive prelude, and the opening song by a shepherd, are musically of great interest. It begins with a horn passage, and at the rise of the curtain it is still night, and we see the dawn break, and hear the many bells from the church towers, one of the most striking sounds of the Eternal city.
The pastoral melody of the shepherd has a plaintive character, and he sings:
Day now is breaking,
The weary world awaking,
Lending new sorrow
And sadness to the morrow.
And the sheep-bells come in with their jangle as the shepherd continues, with a suggestion of a love theme:
If you could prize me
To live I might try,
But if you despise me
I may as well die.
Then the church bells continue the strain, now near, now afar.
