Among the historical romances, contained in the Romancero, those in which anecdotes of the Moorish war, or the heroic and gallant adventures of Moorish knights, are poetically treated, seem, for the most part, to belong to the latter half of the fifteenth century. All these romances relate to the civil wars of Granada, the last Moorish principality in Spain. The civil dissensions of Castile retarded for upwards of half a century the conquest of Granada, which was at length effected in the year 1492, by the united power of Isabella of Castile and Ferdinand of Arragon. During this last period of the conflict between the Christians and the Mahometans of Spain, the former became more intimately acquainted with the history of the latter. As the last blow for the deliverance of the Peninsula was now about to be struck, all that related to the Moors was doubly interesting to the Castilians. The two rival factions, the Zegris and the Abencerrages, whose mutual enmity accelerated the fall of Granada, were, in a particular manner, the objects of their adversaries attention. About this period it seems to have become a fashion among the Spanish romance writers, to select from the events of Moorish history, materials for their songs; and in these romances the heroes of the Zegri and Abencerrage tribes sustain the principal characters. Even after the conquest of Granada, the interest excited throughout Spain by that great national event, still continued; and, doubtless, many romances, the subjects of which are borrowed from Moorish history, were produced in the sixteenth century.[121] The first Spanish pastoral romances, were probably produced during the last ten years of the fifteenth century. But no distinct traces exist of the rise of this species of poetry in Spain. In the poetry of the age of John II. neither pastoral names nor ideas appear, except in the satyrical poem, entitled, _Mingo Rebulgo_, which will be hereafter noticed. Pastoral dramas are, however, to be found in the works of Juan de la Enzina, who flourished towards the close of the fifteenth century, and of whom we shall also have occasion to speak more at large. The Spanish pastoral poetry seems, shortly after its rise, to have been blended with the romantic poetry. Many of the most beautiful narrative pieces in the _Romancero general_ are properly pastoral romances. It is quite impossible to ascertain correctly to what age these bucolicks belong;[122] and it has, hitherto, proved equally impossible to obtain any positive information respecting the origin of the facetious and satyrical romances and songs, dispersed through the _Romancero general_.[123]
