The Market at Tlatelolco

Tlatelolco, the northern twin city of Tenochtitlan, set on the island in the lakes of the Basin of Mexico. By the early sixteenth century it was the largest market in the Americas and among the largest in the world. Its roots predate Mexica political dominance of the basin.

When Hernán Cortés wrote to Charles V in 1520, he reached for superlatives he rarely used. The great market he described—orderly, vast, fragrant, loud with commerce—held more than sixty thousand people on a given day, a figure that stopped the emperor's secretary cold and has anchored the imagination of every food historian who followed. Bernal Díaz del Castillo, a soldier with no reason to flatter, said he and his companions stood on the great temple and could not take it all in, that some who had been in Rome and Constantinople said they had seen nothing so well composed or so large. Both men were looking at Tlatelolco. Tlatelolco occupied the northern portion of the island of Tenochtitlan, the Mexica capital set in the shallow lakes of the Basin of Mexico. It was politically distinct from Tenochtitlan—a twin city, not a neighbourhood—and its market had been the commercial engine of the basin for generations before the Mexica rose to dominance. By the time the Spanish arrived in 1519, the market operated under the jurisdiction of the pochteca, the long-distance merchants who were a class unto themselves: they had their own patron deity, their own courts, their own codes of conduct on the road. They brought goods from the Gulf coast, from the tropical lowlands, from the Pacific, and from the distant south. The market's reach was, in effect, the reach of the Triple Alliance and then some. What Cortés, Díaz, and the priest Francisco López de Gómara described—each drawing on the other or on common testimony—was a market segmented by commodity with a precision that rivalled anything in early modern Europe. There were streets of goldsmiths, of featherworkers, of potters. There were slaves, tethered upright to poles, sold under regulations Cortés noted with some admiration. And there was food, in a density and variety that tells us more about pre-Columbian cuisine than almost any other single source. The produce stalls held maize in every form the basin knew: dried ear, shelled grain, fresh green cob, ground masa, made tortillas, made tamales. Maize by then had been shaped by human selection for at least eight thousand years in Mesoamerica, and the market concentrated the regional diversity of that long work—different races, different colours, different textures—into a single trading floor. Alongside it were chiles, dried and fresh, stacked by type, because Mesoamerica had been domesticating Capsicum annuum in centre-east Mexico for perhaps six and a half millennia. Squash, beans, tomatoes—the milpa companions—lay in their sections. Avocados, chayotes, quelites of a dozen kinds, mushrooms, nopales, tunas, sapotes, mamey, guava, pineapple. There were live turkeys and dogs raised for the table, venison, rabbit, fish from the lake and from the coasts carried in on the backs of the tamemes, the porters who formed the arteries of a world without wheeled transport or draft animals. There were insects: dried grasshoppers, the axayácatl egg cakes skimmed from the lake surface, ants, larvae. There was chocolate—cacao beans both as currency and as commodity, traded in counted lots—and there were prepared drinks sold by women who moved through the market crowd. Pulque, the fermented maguey sap, was available but governed by social rules strict enough to have been codified; Sahagún's later account in the Florentine Codex preserves something of those rules even as the Nahua scholars who compiled the work with him were themselves working under colonial conditions. The Florentine Codex, completed in 1577, is not a market document but it is one of the richest sources for understanding what the market's goods became in the kitchen: how turkey was prepared, how tamales were filled and shaped, how cacao was toasted on the comal, ground on the metate, beaten with water and poured from a height to build the foam that mattered as much as flavour. Bernardino de Sahagún compiled this knowledge with Nahua collaborators whose names are not all recorded, a loss the history of Mexican gastronomy has never fully reckoned with. The market also makes visible the political economy of food. Many of the goods in Tlatelolco arrived as tribute—the Mexica state extracted cacao, dried chiles, maize, cloth, and a hundred other commodities from subject peoples across a wide geography. The Totonac of the Gulf coast, who would ally with Cortés in 1519, were among those tributaries; Totonac farmers had been tending vanilla orchids and nurturing the knowledge of their curing for generations. The market thus concentrated not only flavour but power: to walk its aisles was to walk through the material expression of an empire. Tlatelolco did not survive the siege of 1521 intact. The lake was gradually drained, the island merged with the mainland, the market suppressed and replaced by the colonial economy centred on the Plaza Mayor. What persisted was the practice: the daily market, the gendered labour of selling, the taxonomy of goods by type, the negotiation over freshness and price. Mexico's great covered markets—the Mercado de Jamaica, the Mercado Benito Juárez in Oaxaca, the Lucas de Gálvez in Mérida—are not descendants in any unbroken genealogy, but they carry forward a logic of commerce and community that the witnesses of 1519 would have recognised at once.

The market is evidence of culinary range: the variety of chiles, the maize races, the live and dried proteins, the prepared foods sold ready to eat all confirm that pre-Columbian cuisine in the Basin of Mexico was neither simple nor monotonous. The concentration of cacao, vanilla, and dried chiles in one place meant that complex combinations of flavour were not exceptional but routine.
