Upon leaving office in 1716, the Duke of Linares, the viceroy of New Spain, warned his successor of a particularly vexing issue: the question of what to do about Mexico City's Baratillo marketplace. “There is in the Plaza of Mexico,” he wrote, “a traffic prohibited by law or decree that is so problematic that ending it has been a great challenge for me, being that what is stolen [in the city] is sold there, only disguised.” Hipólito Villarroel, writing his treatise about the decadence of Mexico City more than a half-century later, was no more sparing in his description of the market. He referred to it as the “cave or depository for the thieving committed by artisans, maids, and servants, and, in sum, all the plebeians—Indians, mulattos, and the other castas—that are permitted to inhabit this city.” The market was even the subject of a book-length satirical manuscript, written in 1754. Pedro Anselmo Chreslos Jache's unpublished “Ordenanzas del Baratillo” is a legal code for a world turned upside down, where the mixed-race castas reigned and Spaniards were ostracized, and where “four thousand vagabonds” congregated every day to be instructed by “doctors in the faculty of trickery.”
