Considering what happened on the morning of the 10th of May, we should now presume that the second opening of the abscess, whether by Vesalius or someone else, relieved the pressure on the brain; that a critical period of exhaustion followed, probably prolonged by the Moor’s premature caustic, which stopped the suppuration:  but that God’s good handiwork, called nature, triumphed at last; and that therefore it came to pass that the prince was out of danger within three days of the operation.  But he was taught, it seems, to attribute his recovery to a very different source from that of a German knife.  For on the morning of the 9th, when the Moor was gone, and Don Carlos lay seemingly lifeless, there descended into his chamber a Deus e machina, or rather a whole pantheon of greater or lesser deities, who were to effect that which medical skill seemed not to have effected.  Philip sent into the prince’s chamber several of the precious relics which he usually carried about with him.  The miraculous image of the Virgin of Atocha, in embroidering garments for whom, Spanish royalty, male and female, has spent so many an hour ere now, was brought in solemn procession and placed on an altar at the foot of the prince’s bed; and in the afternoon there entered, with a procession likewise, a shrine containing the bones of a holy anchorite, one Fray Diego, “whose life and miracles,” says Olivarez, “are so notorious;” and the bones of St. Justus and St. Pastor, the tutelar saints of the university of Alcala.  Amid solemn litanies the relics of Fray Diego were laid upon the prince’s pillow, and the sudarium, or mortuary cloth, which had covered his face, was placed upon the prince’s forehead.

Modern science might object that the presence of so many personages, however pious or well intentioned, in a sick chamber on a hot Spanish May day, especially as the bath had been, for some generations past, held in religious horror throughout Spain, as a sign of Moorish and Mussulman tendencies, might have somewhat interfered with the chances of the poor boy’s recovery.  Nevertheless the event seems to have satisfied Philip’s highest hopes; for that same night (so Don Carlos afterwards related) the holy monk Diego appeared to him in a vision, wearing the habit of St. Francis, and bearing in his hand a cross of reeds tied with a green band.  The prince stated that he first took the apparition to be that of the blessed St. Francis; but not seeing the stigmata, he exclaimed, “How?  Dost thou not bear the marks of the wounds?” What he replied Don Carlos did not recollect; save that he consoled him, and told him that he should not die of that malady.
