Entrance of Demetrius into Moscow. Great splendor, but of a military kind. Poles and Cossacks compose the procession. Gloom and terror mingle with the demonstrations of joy. Distrust and misfortune surround the whole.

Romanow, who came to the army too late, has returned to Moscow to protect Feodor and Axinia. It is all in vain; he is himself thrown into prison. Axinia flies to Marfa, and at her feet implores protection against the Poles. Here Demetrius sees her, and a violent and irresistible passion is kindled in his breast. Axinia detests him.

DEMETRIUS as Czar. A fearful element sustains him, but he does not control it: he is urged on by the force of strange passions. His inward consciousness betokens a general distrust; he has no friend on whom he can rely. Poles and Cossacks, by their insolent licentiousness, injure him in the popular opinion. Even that which is creditable to him—his popular manners, simplicity, and contempt of stiff ceremonial, occasions dissatisfaction. Occasionally he offends, through inadvertency, the usages of the country. He persecutes the monks because he suffered severely under them. Moreover, he is not exempt from despotic caprices in the moments of offended pride. Odowalsky knows how to make himself at all times indispensable to him, removes the Russians to a distance, and maintains his overruling influence.

DEMETRIUS meditates inconstancy to Marina. He confers upon the point with the Archbishop Iob, who, in order to get rid of the Poles, falls in with his desire, and puts before him an exalted picture of the imperial power.

MARINA appears with a vast retinue in Moscow. Meeting with Demetrius. Hollow and cold meeting on both sides; she, however, wears her disguise with greater skill. She urges an immediate marriage. Preparations are made for a magnificent festival.

By the orders of Marina a cup of poison is brought to Axinia. Death is welcome to her; she was afraid of being forced to the altar with the Czar.

Violent grief of Demetrius. With a broken heart he goes to the betrothal with Marina.

After the marriage Marina discloses to him that she does not consider him to be the true Demetrius, and never did. She then coldly leaves him in a state of extreme anguish and dismay.

Meanwhile SCHINSKOI, one of the former generals of the Czar Boris, avails himself of the growing discontent of the people, and becomes the head of a conspiracy against Demetrius.

ROMANOW, in prison, is comforted by a supernatural apparition. Axinia's spirit stands before him, opens to him a prospect of happier times in store, and enjoins him calmly to allow destiny to ripen, and not to stain himself with blood. ROMANOW receives a hint that he may himself be called to the throne. Soon afterwards he is solicited to take part in the conspiracy, but declines.
