His mother had died in 1849, and in 1866 his father, who had been one of his most constant companions since his wife's death, died also. Thereafter, he and his sister Sarianna, who had passed a life of devotion to their parents, became inseparable. Though England was their home, they spent many summers in Brittany, as his poems indicate, and now and then returned to Italy, where his son was established finally as a painter.

In 1868 appeared the six volume uniform edition of his poems, and immediately afterward began the publication, to be completed in four volumes, of The Ring and the Book. Mrs. Orr traces, in an ingenious manner, the influence which Mrs. Browning's personality had in the conception of Pompilia in this poem. However much a single character may have been affected, it is easy to believe that this elaborate construction building in Browning's mind during the closing years of his wife's life and actually brought into existence in the years immediately following was, more than any single work, a great monument which the poet raised to the memory of that companion whose own poetic achievement always seemed to him of a higher worth than his own. "The simple truth is," he wrote to a common friend, "that she was the poet and I the clever person by comparison: remember her limited experience of all kinds, and what she made of it. Remember, on the other hand, how my uninterrupted health and strength and practice with the world have helped me."

After The Ring and the Book the only new departure, so to speak, of Browning's genius was in the group of poems which were built upon the foundation of Greek poetry. In 1871 appeared Balaustion's Adventure, in 1875 Aristophanes' Apology, and in 1877 The Agamemnon of Æschylus. They have their value as expressive of Browning's catholicity, and more particularly as his one great literary feat. With all his interest in Italy, and his delving in Renaissance literature, there can scarcely be said to be any criticism of Italian literature in the form of his own poetry. In like manner his dramatic works are not, except in a very remote or general sense, criticism of the Elizabethan drama. But his three poems above named do represent the thought and criticism of a Gothic mind confronting and admiring the Greek art and thought. Browning in these works is not a reproducer in his own terms of Greek life; he is a poet of varied experience, who, coming in contact with a great and distinct manifestation of human life, is moved to strike in here also with his thought and fancy, and because of the very elemental nature of the material, to find the keenest delight in exercising his genius upon it.

Meanwhile the facility which his long and varied practice with the English language had brought him made every new subject that appealed to him a plaything for his fertile imagination; and the speculative temper which grew upon him as the maturity of experience enlarged and enriched his material for thought, led him into long and tortuous ways. The Ring and the Book stands about midway in the bulk of his work, but whereas all the poetry and drama before that work represent thirty-five years of his life, that which follows, nearly as great in amount, represents but twenty years.

In these last years of his life, when fame had come to him and his versatility made him a ready companion, he led a semi-public life. He was in demand in all directions. As Mr. Sharp has rapidly summed it up: "Everybody wished him to come and dine; and he did his utmost to gratify everybody. He said everything; read all the notable books; kept himself acquainted with the leading contents of the journals and magazines; conducted a large correspondence; read new French, German, and Italian books of mark; read and translated Euripides and Æschylus; knew all the gossip of the literary clubs, salons, and the studios; was a frequenter of afternoon-tea parties; and then, over and above it, he was Browning: the most profoundly subtle mind that has exercised itself in poetry since Shakespeare."

In 1881 was founded the English Browning Society, one of the most singular testimonials to the interest awakened by a contemporaneous poet known in literary history. The great mass of his writings, the recondite nature of some of the material which he had used, but more than all, the astounding variety of problems in human life and character which he had presented and either solved or opened the way to solve, made Browning an object of the greatest interest to the curious, the sympathetic, and the restless of his day. Any such movement has on its edge a frayed sort of membership, but no one can note the names of members or read the communications which appear in the society's proceedings without recognizing the intellectual ability that carried the movement along. Browning's own attitude toward the society is pretty clearly expressed in the following words which he wrote to Mr. Edmund Yates at the time of the society's foundation:—

"The Browning Society, I need not say, as well as Browning himself, are fair game for criticism. I had no more to do with the founding it than the babe unborn; and, as Wilkes was no Wilkesite, I am quite other than a Browningite. But I cannot wish harm to a society of, with a few exceptions, names unknown to me, who are busied about my books so disinterestedly. The exaggerations probably come of the fifty-years'-long charge of unintelligibility against my books; such reactions are possible, though I never looked for the beginning of one so soon. That there is a grotesque side to the thing is certain; but I have been surprised and touched by what cannot but have been well intentioned, I think. Anyhow, as I never felt inconvenienced by hard words, you will not expect me to wax bumptious because of undue compliment: so enough of 'Browning'—except that he is yours very truly 'while the machine is to him.'"

In 1887 Browning removed to a more agreeable quarter in De Vere Gardens in the west end of London, and with his affection for Asolo, he set about purchasing a residence there in 1889, and it was while engaged in negotiations for the purchase that he was taken ill with bronchial troubles, and died at his son's home in Venice, December 12, 1889. He was buried in Poet's Corner, Westminster Abbey, on the last day of the year. Italy rightly divided honors with England, and on the outer wall of the Rezzonico Palace in Venice is a memorial tablet with the inscription:—
