Philip’s failure left the Milanese Inquisition in its unsatisfactory condition. There was one burning question especially which refused to be settled. Political considerations of the greatest moment required the maintenance of friendly relations with the Catholic Cantons of Switzerland, but the Catholic Cantons were deeply infected with heresy. Moreover the financial interests of the Milanese called for free commercial intercourse with their northern neighbors while, at the same time, the rules of the Inquisition forbade the residence of heretics and dealings with them. It was impossible to reconcile the irreconcileable--to erect a Chinese wall between Lombardy and Switzerland, as the Roman Holy Office desired, and at the same time to retain the friendship of the Swiss and maintain contentment among the Lombards. Intolerance had to yield to politics and commerce, but not without perpetual protest. Tullio Albonesi writes, April 12, 1564, to Cardinal Borromeo that he had presented to the Duke of Sessa the letter asking him to cease employing those heretic Grisons, the Capitano Hercole Salice and his sons and had remonstrated with him in accordance with the information received from the inquisitor. The duke was to depart for Spain the next day, but took time to explain that the pope was misinformed as to his wishing to bring heretics to reside in the Milanese; he had arranged to pay them in their own country for the king’s service and had given them greater privileges of trade than were accorded to the Grisons in general under the capitulations and, if this did not please his Holiness, he must treat with the king about it. Albonesi adds that he reported this to the inquisitor who concluded that the only way to stop the trade of these heretics with the Milanese was for the pope to appeal to Philip.[242] The next year we find the Bishop of Brescia, in a letter to Borromeo, alluding to two persons in his diocese suspected of heresy because they caused scandal by dealing with the Grisons.[243]
