Lope finished this play on the 1st of August, 1631, when he was nearly sixty-nine years old; and yet there are few of his dramas, in the class to which it belongs, that are more marked with poetical vigor, and in none is the versification more light and various.[335] The characters, especially those of the father and son, are better defined and better sustained than usual; and the whole was evidently written with care, for there are not infrequently large alterations, as well as many minute verbal corrections, in the original manuscript, which is still extant. [335] This play contains all the usual varieties of measure,--_redondillas_, _tercetas_, a sonnet, etc.; but especially, in the first act, a _silva_ of beautiful fluency. It was not licensed for representation till the 9th of May, 1632,--apparently from the known unwillingness of the court to have persons of rank, like the Duke of Ferrara, brought upon the stage in a light so odious. At any rate, when the tardy permission was granted, it was accompanied with a certificate that the Duke was treated with “the decorum due to his person”; though, even with this assurance, it was acted but once, notwithstanding it made a strong impression at the time, and was brought out by the company of Figueroa, the most successful of the period,--Arias, whose acting Montalvan praises highly, taking the part of the son. In 1634, Lope printed it, with more than common care, at Barcelona, dedicating it to his great patron, the Duke of Sessa, among “the servants of whose house,” he says, he “was inscribed”; and the next year, immediately after his death, it appeared again, without the Dedication, in the twenty-first volume of his plays, prepared anew by himself for the press, but published by his daughter Feliciana.[336]
