Four years earlier Garcilaso had been edited by the learned Francisco Sánchez (1523-1601), commonly called _El Brocense_, from Las Brozas, his birthplace, in Extremadura; and an excitable admirer of the poet, Francisco de los Cobos, denounced Sánchez for exhibiting his author's debts by means of parallel passages. The partisans of Sánchez took Herrera's commentary as a challenge, and were not mollified by the fact that Herrera nowhere mentioned Sánchez by name. It had been bad enough that an Extremaduran pundit should edit a Castilian poet; that a mere Andalucían should repeat the outrage was insufferable. It was as though an Englishman edited Burns. The Clan of Clonglocketty (or of Castile) rose as one man, and Herrera was flagellated by a tribe of scurrilous, illiterate patriots. Among his more urbane opponents was Juan Fernández de Velasco, Conde de Haro, son of the Constable of Spain, who published his _Observaciones_ under the pseudonym of Prete Jacopín, and was rapturously applauded for calling Herrera an ass in a lion's skin. It is discouraging to record that Haro's impertinence went through several editions, while Herrera's commentary has never been reprinted.[9] Yet this monument of enlightened learning reveals its author, not only as the best lyrist, but as the acutest critic of his age. Cervantes knew it almost by heart, and he honoured it by writing his dedication of _Don Quixote_ to the Duque de Béjar in the very words of Medina's preface and of Herrera's epistle to the Marqués de Ayamonte. So that, since countless readers have admired a passage from the _Anotaciones_ without knowing it, Herrera the prose-writer has enjoyed a vicarious immortality.
