In the midst of these classical preparations, enters, with a bevy of attendants, the haughty queen-like Agrippina, whom Nero, having sent for to complete his triumph, commands to bend too; but she stoutly refusing, and taking him fiercely to task, objurgating likewise Rome's degenerate gray-beards--great bustle--senate broken up hurriedly--and she, with a "_feri ventrem_," dragged off to be killed by her son's order.

Nero alone with Nattalis by imperial command; his momentary compunction nullified by the wily Iago, who turns off the subject smoothly to a new object of desire: Publius was the only senator not in his place, and Publius has a daughter, the fairest in Rome, Lucia--had not the emperor noticed her among Agrippina's women?
Nero, charmed with any scheme of novelty that may change remorseful thoughts, is induced, nothing loth, to attempt the subtle abduction of the heroine; a body-guard, headed as always by Manlius, ready in the vestibule to escort him, and exit.
Nattalis, alone for a minute, betrays his own selfish schemes concerning Lucia, who had refused him before, and alludes to his secret reasons for urging on the maddened Nero to the worst excesses.
_Third scene_ (or part, or _act_, if it must be so), expounds, in fitting contrast to the foregoing, the tender loves of Lucia and Manlius; a gentle home-scene, a villa and its terraced gardens: also, as Lucia is a Christian, we have, poetically, and not puritanically, an insight into her scruples of conscience as to the heathenism of her lover: and also into _his_ consistent nobility of character, not willing to surrender the religion of his fathers unconvinced.

To them rushes in Publius, who has been warned by friend Galba of the near approach of Nattalis and a guard, to seize Lucia for disreputable Nero: no possible escape, and all urge Lucia to imitate Virginia, Lucretia, and others of like Dian fame, by cowardly self-murder; she is high-principled, and won't: then they--the father and lover--request leave to kill her; conflicting passions and considerable stage effect; Lucia, who with calm courage derides the dastard sacrifice, standing unharmed between those loving thirsty swords: in a grand speech, she makes her quiet departure a test of Manlius' love, and her ultimate deliverance to be a proof to him that her God is the true God, the God who guards the innocent.
Manlius, struck with her martyr-like constancy, professes that if indeed she is saved out of this great trouble, he will embrace her faith, renounce his own, and so break down the of wealth and rank, are alike thrown away upon Publius; at last, the prince promises; and when Publius, after a burst of earnest eloquence, proclaims the new pleasure to consist in _showing mercy_, Nero's utter wrath, his hurricane of hate, revoking that hasty promise, and hurrying away old Publius to die at the same stake with his daughter.
_Seventh_: the catastrophe scene lies in the Coliseum amphitheatre; (I mean the older one, anterior to Vespasian's:) bloody games pictured behind, and those "human torches" at fiery intervals.

Nero, enthroned in side front, surrounded by a brilliant court, amongst whom are some of the conspirators: at other side Publius and Lucia, tied at one stake in white robes, back to back, to die before Nero's eyes, Manlius and soldiers guarding them: he, Manlius, having nobly resolved to test miraculous assistance to the last, but now tremblingly believing the chance of a Providence interfering, since Lucia's escape from Nero at the golden house.

Just as the emperor, after a sarcastic speech, characteristically interlarded with courtier conversation, is commanding the fagot to be lighted, and Lucia's constant faith has bade Manlius _do it_--a rush of Nattalis with attendant conspirators and Rufa the Sibyl, up to Nero; Nattalis strikes him, but the sword breaks short off on the hidden armour; Nero's majestic rising for a moment, asserting himself Caesar still, the inviolable majesty;--suddenly stopped by a centripetal rush of the conspirators; who kill him, (after he has vainly attempted in despair to kill himself,) and Galba sits on the throne, while Nero, unpitied and unhelped, gasps out in the middle his dying speech.
Meanwhile, at the other side, Manlius has killed Nattalis for his treachery, cut the bonds of Publius and Lucia, and all ends in moral justice for the triumph of good, and the defeat of evil; Manlius and Lucia, hand in hand, Publius with white head and upraised hands blessing them, Nero, a mangled corpse, Nattalis in his dying agonies persecuted by the vindictive Rufa, and Galba hailed as Caesar by the assembled Romans.
