The fact that Diego de Zuniga is a frequent combination of names in Spain is an embarrassment to the investigator.  It is noticeable that Luis de Leon’s references seem to imply some doubt as to his opponent’s real name; he is obviously uncertain whether his accuser should be called Zuniga or Rodriguez,[109] and in this uncertainty he is not alone.[110] It appears that there were at least two Augustinians known as Diego de Zuniga in Luis de Leon’s time; it further appears that neither of the two inherited from his father the surname which he habitually used.  Both men claimed relationship with the Duque de Bejar—­it was to the seventh Duque de Bejar that Cervantes dedicated the First Part of Don Quixote in 1605—­and both assumed the family name of that illustrious stock.[111] The original name of the more celebrated of these Zunigas was Diego Arias;[112] the original name of the less celebrated was Rodriguez.[113] This is not decisive, but it may well be one of those small facts which speak volumes.  Chronology confirms the conclusion to be drawn from these considerations.  The Zuniga who appeared against Luis de Leon at Valladolid was evidently professed as early as 1559 or 1560;[114] the more celebrated Zuniga was not professed till 1566.[115] General considerations point in the same direction.  The views of Zuniga (alias Arias) were approximately those of Luis de Leon;[116] he viewed matters from the same standpoint, was himself a university professor,[117] and had something of Luis de Leon’s fearlessness.[118] Zuniga (alias Rodriguez) was a man of a very different type:  pedantically attached to the letter of the law, morbidly scrupulous on points of discipline.  There seems to be no touch of burlesque intention in Luis de Leon’s presentment of the man.  According to Luis de Leon, Zuniga (alias Rodriguez) was half-crazed with vanity, much given to boasting of the esteem in which he was held at the Papal Court.  On one occasion, the fatuous Zuniga produced a short treatise entitled Manera para aprender todas las ciencias, and, stating that he proposed sending this pamphlet to the Pope, made bold to ask what his interlocutor thought of it.  Can he have been vain enough to expect a favourable verdict?  If so, he did not know his man.  Luis de Leon drily expressed his regret that a work destined for the Pope should be so slight and should contain a number of rather commonplace passages such as might be found in any current book of reference—­though, as he added politely, he assumed that these passages were the fruit of independent reading.  This courteous assumption, which Zuniga hastily assured Luis de Leon was exact,[119] could not alter the fact that the ambitious author had been severely snubbed, and this snub may well have rankled in the mind of a man who is described as ‘vindictive’.  Zuniga had another grievance against Luis de Leon, who had taken a severe view of his companion’s insolence to an official superior at a Provincial
