His _Representación del Nacimiento de Nuestro Señor_, the earliest successor to the _Misterio de los Reyes Magos_, is a liturgical drama written for and played at the convent of Calabazanos, of which his sister was Superior. It consists of twenty octosyllabic stanzas delivered by the Virgin, St. Joseph, St. Gabriel, St. Michael, St. Raphael, an angel, and three shepherds, the whole closing with a cradle-song. Simple as the construction is, it is more elaborate than that of a later play on the Passion, wherein the Virgin, St. John, and the Magdalen appear (though the last takes no part in the dialogue). The refrain or _estribillo_ at the end of each stanza goes to show that this piece was intended to be sung. These primitive essays in the hieratic drama have all the interest of what was virtually a new invention, and their historical importance is only exceeded by that of a secular play, written by Gómez Manrique for the birthday of Alfonso, brother of Enrique IV., in which the Infanta Isabel played one of the Muses. In all three experiments the action is of the slightest, though the dialogue is as dramatic as can be expected from a first attempt. The point to be noted is that Gómez Manrique foreshadows both the lay and sacred elements of the Spanish theatre. His fame has been unjustly eclipsed by that of his nephew, JORGE MANRIQUE, Señor de Belmontejo (1440-1478), a brilliant soldier and partisan of Queen Isabel's, who perished in an encounter before the gates of Garci-Múñoz, and is renowned by reason of a single masterpiece. His verses are mostly to be found in the _Cancionero General_, and a few are given in the _cancioneros_ of Seville and Toledo. Like that of his uncle, Gómez, his vein of humour is thin and poor, and the satiric stanzas to his stepmother border on vulgarity. In acrostic love-songs and in other compositions of a like character, Jorge Manrique is merely clever in the artificial style of many contemporaries—is merely a careful craftsman absorbed in the technical details of art, with small merit beyond that of formal dexterity. The forty-three stanzas entitled the _Coplas de Jorge Manrique por la muerte de su padre_, have brought their writer an immortality which, outliving all freaks of taste, seems as secure as Cervantes' own. An attempt has been made to prove that Jorge Manrique's elegiacs on his father are not original, and that the elegist had some knowledge of Abu 'l-Bakā Salih ar-Rundi's poem on the decadence of the Moslem power in Spain. Undoubtedly Valera has so ingeniously rendered the Arab poet as to make the resemblance seem pronounced: but the theory is untenable, for it is not pretended that Jorge Manrique could read Arabic, and lofty commonplaces on death abound in all literature, from the Bible downwards.
