Two of the dramas contained in this volume are the most celebrated of all Calderon's writings. The first, "La Vida es Sueno", has been translated into many languages and performed with success on almost every stage in Europe but that of England. So late as the winter of 1866-7, in a Russian version, it drew crowded houses to the great theatre of Moscow; while a few years earlier, as if to give a signal proof of the reality of its title, and that Life was indeed a Dream, the Queen of Sweden expired in the theatre of Stockholm during the performance of "La Vida es Sueno". In England the play has been much studied for its literary value and the exceeding beauty and lyrical sweetness of some passages; but with the exception of a version by John Oxenford published in "The Monthly Magazine" for 1842, which being in blank verse does not represent the form of the original, no complete translation into English has been attempted. Some scenes translated with considerable elegance in the metre of the original were published by Archbishop Trench in 1856; but these comprised only a portion of the graver division of the drama. The present version of the entire play has been made with the advantages which the author's long experience in the study and interpretation of Calderon has enabled him to apply to this master-piece of the great Spanish poet. All the forms of verse have been preserved; while the closeness of the translation may be inferred from the fact, that not only the whole play but every speech and fragment of a speech are represented in English in the exact number of lines of the original, without the sacrifice, it is to be hoped, of one important idea.
