Charles took, moreover, great interest in the mechanism of timepieces. He had a good number of clocks and watches ticking together in his apartments; and a story has obtained credit, that the difficulty he found in making any two of them keep the same time drew from him an exclamation on the folly of attempting to bring a number of men to think alike in matters of religion, when he could not regulate any two of his timepieces so as to make them agree with each other; a philosophical reflection for which one will hardly give credit to the man who, with his dying words, could press on his son the maintenance of the Inquisition as the great bulwark of the Catholic faith. In the gardens of Yuste there is still, or was lately, to be seen, a sun-dial constructed by Torriano to enable his master to measure more accurately the lapse of time as it glided away in the monotonous routine of the monastery.[302] Though averse to visits of curiosity or idle ceremony,[303] Charles consented to admit some of the nobles whose estates lay in the surrounding country, and who, with feelings of loyal attachment to their ancient master, were anxious to pay their respects to him in his retirement. But none who found their way into his retreat appear to have given him so much satisfaction as Francisco Borja, duke of Gandia, in later times placed on the roll of her saints by the Roman Catholic Church. Like Charles, he had occupied a brilliant eminence in the world, and like him had found the glory of this world but vanity. In the prime of life, he withdrew from the busy scenes in which he had acted, and entered a college of Jesuits. By the emperor's invitation, Borja made more than one visit to Yuste; and Charles found much consolation in his society, and in conversing with his early friend on topics of engrossing interest to both. The result of their conferences was to confirm them both in the conviction, that they had done wisely in abjuring the world, and in dedicating themselves to the service of Heaven. The emperor was also visited by his two sisters, the dowager queens of France and Hungary, who had accompanied their brother, as we have seen, on his return to Spain. But the travelling was too rough, and the accommodations at Yuste too indifferent, to encourage the royal matrons to prolong their stay, or, with one exception on the part of the queen of Hungary, to repeat their visit.
