Mr. Browning gives, in conclusion, a test by which the relative merit of any two real poets may be gauged. _The greater is he who leads the happier life_. To be a poet is to see and feel. To see and feel is to suffer. His is the truest poetic existence who enslaves his sufferings, and makes their strength his own. He who yokes them to his chariot shall win the race.[83]

"CENCIAJA" signifies matter relating to the "Cenci;"[84] and the poem describes an incident extraneous to the "Cenci" tragedy, but which strongly influenced its course. This incident was the murder of the widowed Marchesa dell' Oriolo, by her younger son, Paolo Santa Croce, who thus avenged her refusal to invest him with his elder brother's rights. He escaped the hands of justice, though only to perish in some other disastrous way. But the matricide had been committed on the very day which closed the trial of the Cenci family for the assassination of its Head; and it sealed Beatrice's fate. Her sentence seemed about to be remitted. The Pope now declared that she must die.

... "Paolo Santo Croce Murdered his mother also yestereve, And he is fled: she shall not flee at least!" (vol. xiv. p. 104.)

The elder son of the Marchesa, Onofrio Marchese dell' Oriolo, was arrested on the strength of an ambiguous scrap of writing, which appeared to implicate him in his brother's guilt; and subjected in prison to such a daily and day-long examination on the subject of this letter, that his mind gave way, and the desired avowal was extracted from him. He confessed to having implied, under reserves and conditions which practically neutralized the confession, his assent to his mother's death. He was beheaded accordingly; and the Governor of Rome, Taverna, who had conducted the inquisition, was rewarded by a Cardinal's hat. Other motives were, however, involved in the proceeding than the Pope's quickened zeal for justice. He had entrusted the case to his nephew, Cardinal Aldobrandini; and it was known that the Cardinal and the Marchese had courted the same lady, and the latter unwisely flaunted the possession of a ring which was his pledge of victory.

This story, with other details which I have not space to give, was taken from a contemporary Italian chronicle, of which some lines are literally transcribed.
