There can be no doubt, however, that the volume appeared in 1635 or 1636 as stated. In 1637 Don Joseph Calderon published the "Second Part" of his brother's dramas containing like the former volume twelve plays.* In his dedication of this volume to D. Rodrigo de Mendoza, Joseph Calderon expressly alludes to the First Part of his brother's comedies which he had "printed." "En la primera Parte, Excellentissimo Senor, de las comedias que imprimi de Don Pedro Calderon de La Barca, mi hermano," etc. This of course settles the fact of the prior publication of the first Part. It is singular, however, to find that the most famous of all Calderon's dramas should have been frequently ascribed to Lope de Vega. So late as 1857 it is given in an Italian version by Giovanni La Cecilia, under the title of "La Vita e un Sogno", as a drama of Lope de Vega, with the date 1628. This of course is a mistake, but Senor Hartzenbusch, who makes no allusion to this circumstance, admits that two dramas of Lope de Vega, which it is presumed preceded the composition of Calderon's play turn on very nearly the same incidents as those of "La Vida es Sueno". These are "Lo que ha de ser", and "Barlan y Josafa". He gives a passage from each of these dramas which seem to be the germ of the fine lament of Sigismund, which the reader will find translated in the present volume. [footnote] *In the library of the British Museum there is a fine copy of this "Segunda Parte de Comedias de Don Pedro Calderon de la Barca" Madrid, 1637. Mr. Ticknor mentions (1863) that he too had a copy of this interesting volume. Senor Hartzenbusch, in the edition of Calderon's "La Vida es Sueno", already referred to (Madrid, 1872), prints the passages from Lope de Vega's two dramas, but in neither of them, he justly remarks, can we find anything that at all corresponds to this "grandioso caracter de Segismundo." The second drama in this volume, "The Wonderful Magician", is perhaps better known to poetical students in England than even the first, from the spirited fragment Shelley has left us in his "Scenes from Calderon." The preoccupation of a subject by a great master throws immense difficulties in the way of any one who ventures to follow in the same path: but as Shelley allowed himself great licence in his versification, and either from carelessness or an imperfect knowledge of Spanish is occasionally unfaithful to the meaning of his author, it may be hoped in my own version that strict fidelity both as to the form as well as substance of the original may be some compensation for the absence of those higher poetical harmonies to which many of my readers will have been accustomed.
