The two parties in the Court fought over the little power which the all-absorbing personal government of Philip left to his ministers. At the head of one was the great Duque de Alba, who represented the purely warlike policy of force; the other was led by the Prince of Évoli, D. Ruy Gómez, representing the opposite policy of diplomacy, intrigue and peace.
The followers of the first were the Prior D. Antonio de Toledo, the Prince of Mélito, the Marqués de Aguilar, and the secretary, Zayas; the partisans of the other were the Archbishop of Toledo, D. Gaspar de Quiroga, the Marqués de los Vélez, Mateo Vázguez, Santoyo and Gonzalo Pérez.
It is most extraordinary that the open, generous nature of D. John did not lead him to the side of the Duque de Alba, and that, on the contrary, he joined the Prince of Évoli, who rather represented the lawyers and churchmen, but no doubt the explanation must be sought in the cleverness which this party displayed in attracting him, guessing the genuine great qualities of the illustrious youth.
They first provided Antonio Pérez, who with adroit flatteries, in which he was a past master, and with studied confidences as between man and man, made D. John understand how much he was appreciated by the coterie of Ruy Gómez, the great hopes they placed in his bravery and influence, and how much they were trying to work on the King to name him Captain-General of the Mediterranean galleys, as he had already promised.
All of which, it is unnecessary to say, assumed a great air of truth in the mouth of the son of Gonzalo Pérez, who through this channel might well know what was happening, since it was intended that he should succeed his father in the appointment.
When the ground was sufficiently prepared for such an important personage to step in without danger, Ruy Gómez arranged a meeting, as if by accident, with D. John, and repeated the same things in a different way, adding that his appointment was already settled and that it was a magnificent one, as also was the ship "Capitana," which was being got ready at Barcelona, that it would not be long before his desire of fighting the Turks was gratified at the head of a brilliant squadron, and that was a foregone conclusion.
Gonzalo Pérez died this year (1566), and Philip II resisted the efforts of Ruy Gómez to obtain his father's vacant secretaryship for Antonio Pérez, giving as a pretext, not his youth, for he was thirty-two, but the laxity of his life and the depravity of his morals.
Taking, however, as a sign of repentance and amendment Antonio Pérez's marriage with Doña Juana de Coello Bozmediano, which was celebrated on the 3rd of January, 1567, D. Philip hastened to bestow on him Gonzalo Pérez's secretaryship, which delighted D. John as much as if it were the summit of his ambitions or the triumph of his interests.
Once having caught the Prince on the weak side of his ambitions, they wished to do so on that of his platonic love. The Princess de Évoli undertook this, attracting him to her house, giving in his honour balls and banquets, and putting before his eyes, and even within his reach, the lady, the object of his then honest intentions, Doña Maria de Mendoza, one of the ladies of the Palace, and it is thought a near kinswoman of the restless, intriguing Princess. Such artifices did the Princess use to influence the will and gain the confidence of the grateful D. John, that years afterwards, when she was no longer the intriguing, restless lady of former times, but the shameless, criminal woman who plotted with Antonio Pérez perfidious treasons which were, incidentally, to ruin D. John himself, the latter wrote, nevertheless, to his friend D. Rodrigo de Mendoza with the utmost affection and blind confidence: "I kiss the hands of my one-eyed lady, and I do not say her eyes until I write it to her, in order that she may remember this her friend, so much her friend now, who cannot do more, nor has anything else to offer her in payment of his debt. And the reason that this message is sent with so much prudence is that, coming from such a distance, it cannot be otherwise."
