Gomez. I saw.

Philip. Distraction!
Suspicion then——

Gomez. Is certainty.

Philip. And yet
Philip is unrevenged?

Gomez. Think——

Philip. I have thought;
Follow you me.

Act II, Scene 5.

In the third act Carlos acquaints Isabella with her imprudence, in speaking in his favor to the tyrant, and the probable consequences of addressing thus one whose mercy is but the pledge of evil. She cannot however believe the king an unnatural father, but promises never to repeat so perilous an effort. After her departure, Gomez enters and announces the king. To his hypocritical offers of service, Carlos deigns no reply, but leaves him without uttering a word. Philip, with his nobles and ministers, then appears upon the stage; and having ordered the doors to be closed, in a set speech, accuses his son of treason and an attempt upon his life; produces the blade which he states to have fallen at his feet when the baffled assassin fled from him; and having played off a feigned reluctance to hear the condemnation of the criminal, leaves the sentence to their decision. Gomez, with affected sympathy for the sufferings of the father, confirms the accusation of treason by producing intercepted letters alleged to have been written by the prince, that prove a treacherous correspondence with the French; while Leonardo completes the catalogue of crimes by charging him with heresy, and hurling against him the denunciations of the church. They are proceeding to adjudge him to death, encouraged by Philip, who tells them they stand in the presence, not of the father, but the king, when Perez craves permission to speak, and boldly vindicates the innocence of his friend. The king, in displeasure, breaks up the assembly; his anger at the boldness of Perez is only equalled by his wonder that such a spirit could exist in his court.

“Alma si fatta
Nasce ov'io regno? e dov'io regno, ha vita?”

Carlos is afterwards surprised alone at night, by a body of soldiers, led by his father. To the displeasure of Philip at finding him armed at such an hour, he answers by submitting himself to the royal will. The scene that ensues between father and son is terrible, and powerfully depicts the native cruelty of the tyrant. He accuses the youth of secret and atrocious designs—of attempted parricide.
