"El Magico Prodigioso" appeared for the first time in the same volume as "La Vida es Sueno", prepared for publication in 1635 by Don Joseph Calderon. The translation is comprised in the same number of lines as the original, and all the preceding remarks on "Life is a Dream", whether in reference to the period of the first publication of the drama in Spain, or the principles I kept in view while attempting this version may be applied to it. As in the Case of "Life is a Dream", "The Wonderful Magician" has previously been translated entire by an English writer, ("Justina", by J.H. 1848); but as Archbishop Trench truly observes, "the writer did not possess that command of the resources of the English language, which none more than Calderon requires." The Legend on which Calderon founded "El Magico Prodigioso" will be found in Surius, "De probatis Sanctorum historiis", t. V. (Col. Agr. 1574), p. 351: "Vita et Martyrium SS. Cypriani et Justinae, autore Simeone Metaphraste", and in Chapter cxlii, of the "Legenda Aurea" of Jacobus de Voragine "De Sancta Justina virgine". The martyrdom of the Saints took place in the year 290, and their festival is celebrated by the Church on the 26th of September. Mr. Ticknor in his History of Spanish Literature, 1863, volume ii. p. 369, says that the Wonder-working Magician is founded on "the same legend on which Milman has founded his 'Martyr of Antioch.'" This is a mistake of the learned writer. "The Martyr of Antioch" is founded not on the history of St. Justina but of Saint Margaret, as Milman himself expressly states. Chapter xciii., "De Sancta Margareta", in the "Legenda Aurea" of Jacobus de Voragine contains her story. The third translation in this volume is that of "The Purgatory of St. Patrick". This, though perhaps not so famous as the two preceding dramas, is intended to be given by Don P. De la Escosura, in a selection of Calderon's finest "comedias", now being edited by him for the Spanish Academy, as the representative piece of its class -- namely, the mystical drama founded on the lives of Saints. Mr. Ticknor prefers it to the more celebrated "Devotion of the Cross," and says that it "is commonly ranked among the best religious plays of the Spanish theatre in the seventeenth century."
