Still, it would be wrong to think that Berceo contents himself with mere servile reproduction, or that he trespasses in the manner of a vulgar plagiary. Seven of his legends he seeks elsewhere than in Gautier, and he takes it upon himself to condense his predecessor's diffuse narration. Thus, where Gautier needs 1350 lines to tell the legend of St. Ildefonsus, or 2090 to give the miracle of Theophilus, Berceo confines himself to 108 and to 657 lines. Gautier will spare you no detail; he will have you know the why, the when, the how, the paltriest circumstance of his pious story. Beside him Berceo shines by his power of selection, by his finer instinct for the essential, by his relative sobriety of tone, by his realistic eye, by his variety of resource in pure Castilian expression, by his richer melody, and by the fleeter movement of his action. In a word, with all his imperfections, Berceo approves himself the sounder craftsman of the two, and therefore he finds thirty readers where the Prior of Vic-sur-Aisne finds one. Small and few as his opportunities were, he rarely failed to use them to an advantage; as in the invention of the singular rhymed octosyllabic song—with its haunting refrain, _Eya velar!_—in the _Virgin's Lament_ (stanzas 170-198). This argues a considerable lyrical gift, and the pity is that the most of Berceo's editors should have been at such pains to hide it from the reader. In the ten thousand lines of the _Libro de Alexandre_ are recounted the imaginary adventures of the Macedonian king, as told in Gautier de Lille's _Alexandreis_ and in the versions of Lambert de Tort and Alexandre de Bernai. Traces of the Leonese dialect negative the ascription to Berceo, and the Juan Lorenzo Segura de Astorga mentioned in the last verses is a mere copyist. The _Poema de Fernán González_, due to a monk of San Pedro de Arlanza, embodies many picturesque and primitive legends in Berceo's manner. But the value of both these compositions is slight.
