Browning's third literary venture was a tragedy, _Strafford_, dedicated to Macready, at whose request it was written. The drama presents the impeachment, condemnation, and execution of the Earl of Strafford, a statesman who, according to the play, loved the unworthy King Charles the First and sacrificed everything, even to life itself, in his blind loyalty to a master who treacherously deserted him in the hour of need. It was a topic to which Browning had already given much thought, for he had the preceding year completed, from materials supplied by Mr. John Forster, a _Life of Strafford_ begun by Forster for Lardner's _Eminent British Statesmen_.[2] The question of the historic truthfulness of the drama is discussed by the historian Gardiner in the Introduction to Miss Emily H. Hickey's edition of _Strafford_. He shows that the play is in its details and "even in the very roots of the situation" untrue to fact, and yet he maintains that in the chief characters there is essential truth of conception. "Every time that I read the play," says Gardiner, "I feel more certain that Browning has seized the real Strafford ... Charles, too, with his faults, perhaps exaggerated, is nevertheless the real Charles." The play was produced at Covent Garden Theater in May, 1837, with Macready as Strafford and Miss Helen Faucit as Lady Carlisle, and was successful in spite of poor scenery and costuming and poor acting in some of the parts. But owing to the financial condition of the theater and the consequent withdrawal of one of the important actors after the fifth night, the play had but a brief run. It was presented again in 1886 under the auspices of the Browning Society, and its power as an acting play "surprised and impressed" the audience.
Before the composition of _Strafford_ Browning had begun a long poem, _Sordello_, which he completed after his first visit to Italy in 1838, and published in 1840. No one of his poems is more difficult to read, and many are the stories told of the dismay occasioned by its various perplexities. The effect of this poem on Browning's fame was disastrous. In fact, after _Sordello_ there began a period, twenty years long, of almost complete indifference in England to Browning's work. The enthusiasm over the promise of his early poems died quite away. Late in life Mr. Browning commented on this period of his literary career as a time of "prolonged desolateness." Yet the years 1841-1846 are the years in which he attained his poetic maturity, and years in which he did some of his best work. During this period he brought out the series somewhat fancifully called _Bells and Pomegranates_. The phrase itself comes from _Exodus_ xxviii, 33, 34. As a title Browning explained it to mean "something like a mixture of music with discoursing, sound with sense, poetry with thought." This cheap serial edition, the separate numbers of which sold at first at sixpence and later at half a crown, included _Pippa Passes_, _King Victor and King Charles_, _Dramatic Lyrics_, _The Return of the Druses_, _A Blot in the 'Scutcheon_, _Colombe's Birthday_, _Dramatic Romances and Lyrics_, _Luria_, and _A Soul's Tragedy_.
