"The Widow's Marriage," in manuscript, and never published, was accepted by Marshall, manager of the Walnut, and is noted by Boker, in a letter to Stoddard, October 12, 1852, the chief handicap confronting him being the inability to find someone suited to take the leading rôle. Stoddard's own comment was:

Whether [it] was ever produced I know not, but I should say not, for the part of the principal character, Lady Goldstraw, is one which no actress whom I remember could have filled to the satisfaction of her creator. The fault of this character (me judice) is that it is too good to be played on a modern stage. It ought to have been written for antiquity two hundred years ago.

Boker was right when he referred to himself as "prolific" at this time. He already had produced, in 1851, according to markings on the manuscript, a piece called "All the World a Mask," and he had written "The Podesta's Daughter," a dramatic sketch, issued, with "Miscellaneous Poems," in 1852. Toward the end of this year, he completed "Leonor de Guzman."

"Her history," he writes to Stoddard, on November 14, "you will find in Spanish Chronicles relating to the reigns of Alfonso XII of Castile and his son, Peter the Cruel. There are no such subjects for historical tragedy on earth as are to be found in the Spanish history of that period. I am so much in love with it that I design following up 'Leonor de Guzman' by 'Don Pedro'. The present tragedy, according to the judgment of Leland, is the very best play I have written, both for the closet and the stage. Perhaps I am too ready to agree with him, but long before he said it I had formed the same judgment."

This tragedy was performed at the Philadelphia Walnut Street Theatre, on October 3, 1853, and at the New York Broadway Theatre, on April 24, 1854. Boker wrote to his friends, showing his customary concern about an actress skilled enough for the rôle of his heroine. When, finally, for the Philadelphia première, Julia Dean was decided upon, he thus expressed his verdict to Stoddard, after the opening performance: "Miss Dean, as far as her physique would admit, played the part admirably, and with a full appreciation of all those things which you call its beauties."

During these years of correspondence with his friends, Boker was determining to himself the distinction between poetic and dramatic style.

"Seriously, Dick," he writes to Stoddard, on October 6, 1850, "there is, to my mind, no English diction for your purposes equal to Milton's in his minor poems. Of course any man would be an intensified ass who should attempt to reach the diction of the 'Paradise Lost', or aspire to the tremendous style of Shakespeare. You must not confound things, though. A Lyric diction is one thing—a Dramatic diction is another, requiring the utmost force and conciseness of expression,—and Epic diction is still another; I conceive it to be something between the Lyric and Dramatic, with all the luxuriance of the former, and all the power of the latter."

He must have written to Taylor in the same vein, for, in a letter from the latter, there is assurance that he fully understands what a slow growth dramatic style must be. But Boker was not wholly wed to theatrical demands; he still approached the stage in the spirit of the poet who was torn between loyalty to poetic indirectness, and necessity for direct dialogue. On January 12, 1853, he writes to Stoddard:

Theatricals are in a fine state in this country; every inducement is offered to me to burn my plays as fast as I write them. Yet, what can I do? If I print my plays, the actors take them up, butcher, alter and play them, without giving me so much as a hand in my own damnation. This is something beyond even heavenly rigour; and so I proceed to my own destruction, with the proud consciousness that, at all events, it is my own act. À propos, have you ever read the English acting copy of my "Calaynos"? A viler thing was never concocted from like materials.

Whether or not the play, "The Bankrupt," preceded or followed the writing of "Francesca da Rimini" in 1853, we have no way of determining; but it would seem that it progressed no further in its stage career than in manuscript form, it being the only play on a modern theme attempted by Boker. Then, it seems, he was hot on the trail of the Francesca love story told in Dante, and used by so many writers in drama and poetry. It is this play, conceded to be his best, which is included in the present collection, and which calls for analysis and history by itself.
