NOT SHOWING UP FOR AN auto da fé was regarded as a Bad Idea everywhere in the Spanish Empire, and especially in Mexico City. Every scrap of land in the town was owned by the Church, and the Holy Surveyors of Rome had (or so Jack phant’sied) come out here and planted Trinitarian transits on the land that had been miraculously reclaimed from Lake Texcoco and hung holy plumb-bobs made of saints’ skulls and stretched cords of spun angels’ hair, driven crucifixes into the ground at strategickal Vertices, and platted the land into quadrilaterals, each one butted snugly against the next; angels might slip through the interstices, but never Indians nor Vagabonds. These parcels had been entrusted to various religious Orders, viz. Carmelites, Jesuits, Dominicans, Augustinians, Benedictines, et cetera , each of which had lost no time in erecting a high stone wall around its property-line to shield it from the intrigues and supposed heresies of the neighboring Orders. This accomplished, they had got to work filling in the middle with churches, chapels, and dormitories. The buildings sank into the soft ground almost as quickly as they were built, which made the place seem much beyond its true age of about a hundred and eighty years. At any rate there was no place to live in Mexico City that was not controlled by one Order or another, and consequently no way not to show up for an auto da fé without its being noticed by someone who’d be apt to take it the wrong way.
