rumours of the Jewish descent of the accused;[103] the gravest fact the witness could allege was Luis de Leon's view that a friar, despite his vow of poverty, might spend a couple of coppers without mortal sin in buying an _Agnus Dei_.[104] Arboleda gives the impression of being a dullard, and this is pretty much the description of him by another member of the Augustinian order--Pedro de Rojas,[105] son of the Marqués de Pozas and afterwards Bishop of Astorga and Osuna. Luis de Leon apparently agreed with Rojas in his estimate of Arboleda's ability, and this may account for his comparative leniency to the poor numbskull. More severe treatment is meted out to another Augustinian, Diego de Zúñiga, whom Luis de Leon brands as a deliberate perjurer.[106] Who was this Zúñiga? He has generally been identified with the Zúñiga who was among the first in Spain to declare in favour of the Copernican theory;[107] this action needed courage and Zúñiga has had his reward. As he is respectfully quoted by Galileo, he has attained something like immortality.[108] There is, however, no conclusive evidence to show that this enlightened writer is the Zúñiga who came under Luis de Leon's lash. The correctness of the current identification is, at least, doubtful. The fact that Diego de Zúñiga 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 Zúñiga 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 Zúñiga 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 Béjar--it was to the seventh Duque de Béjar 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 Zúñigas 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 Zúñiga who appeared against Luis de Leon at Valladolid was evidently professed as early as 1559 or 1560;[114] the more celebrated Zúñiga was not professed till 1566.[115] General considerations point in the same direction. The views of Zúñiga (_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] Zúñiga (_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
