La Venta was located on an almost inaccessible island, surrounded at that time by the Tonalá River; the river now divides the states of Veracruz and Tabasco. As San Lorenzo’s fortunes fell, La Venta’s rose, and between 800 and 400 bce it was the most important site in Mesoamerica.

At the centre of La Venta is a 100-foot (30-metre)-high mound of earth and clay that may well house the tomb of a great Olmec ruler. Immediately north of the Great Mound is a narrow north–south plaza flanked by a pair of long mounds. Beyond the plaza is a ceremonial enclosure surrounded by a “fence” made entirely of upright shafts of columnar basalt. A low, round mound on the north side of the ceremonial enclosure contained several tombs, one of which was surrounded and covered by basalt columns. In this tomb were found the bundled remains of two children, accompanied by magnificent ornaments of jade. Offerings were not only placed with the dead but were also deposited as caches in the site, especially along the north–south axis of the ceremonial centre.

Among the most beautiful objects manufactured by the Olmec were the concave mirrors of iron ore, which were pierced to be worn around the neck. These could throw pictures on a flat surface and could probably start fires on hot tinder. Olmec leaders at La Venta, whether they were kings or priests, undoubtedly used them to impress the populace with their seemingly supernatural powers. Olmec sculptors continued to produce the basalt monuments, including colossal heads and “altars,” that have been found at La Venta. Significantly, an increasing number of monuments were carved in relief, and some of these were stelae with rather elaborate scenes obviously based upon historical or contemporary events.

Olmec colonization in the Middle Formative

From the Middle Formative there are important Olmec sites located along what appears to have been a highland route to the west to obtain the luxury items that seemed to have been so desperately needed by the Olmec elite—e.g., jade, serpentine, iron ore for mirrors, cinnabar, and so forth. Olmec sites in Puebla, the Valley of Mexico, and Morelos are generally located at the ends of valleys near or on major passes; they were perhaps trading stations garrisoned by Olmec troops. The largest of these sites is Chalcatzingo, Morelos, a cult centre located among three denuded volcanic peaks rising from a plain. On a talus slope at the foot of the middle peak are huge boulders on which have been carved Olmec reliefs in La Venta style. The principal relief shows an Olmec woman, richly garbed, seated within the mouth of a cave; above her, cumulus clouds pour down rain.

Similar Olmec reliefs, usually narrative and often depicting warriors brandishing clubs, have been located on the Pacific plain of Chiapas (Mexico) and Guatemala. Since about 1960, spectacular Olmec cave paintings have been found in Guerrero, offering some idea of what the Olmec artists could do when they worked with a large spectrum of pigments and on flat surfaces.

metalwork: Pre-Columbian

Olmec culture or civilization did not spread eastward from its Veracruz–Tabasco centres into the Maya lowlands, but occasional Olmec artifacts have been found in Formative Maya contexts, such as at Seibal, in southern Petén, Guatemala. Maya Formative Period occupations, represented by settled farming villages and well-made ceramics, date to c. 1000 bce in the lowlands of Guatemala and Belize. It seems reasonably certain, however, that at this early date great ceremonial centres, comparable to those of Olmec San Lorenzo or La Venta, were never constructed in the Maya lowlands.

It was formerly thought that the Olmec worshiped only one god, a rain deity depicted as a were-jaguar, but study has shown that there were at least 10 distinct gods represented in Olmec art. Surely present were several important deities of the later, established Mesoamerican pantheon, such as the fire god, rain god, corn god, and Feathered Serpent. Other aspects of mental culture are less well-known; some Olmec jades and a monument from La Venta have non-calendrical hieroglyphs, but none of this writing has been deciphered.

To sum up the Olmec achievement, not only was this the first high culture in Mesoamerica—one that had certainly achieved political statehood—but either it or cultures influenced by it lie at the base of every other Mesoamerican civilization.

Early Monte Albán

Monte Albán is a prominent series of interconnected hills lying near Oaxaca, Mexico. One of these was completely leveled off in Middle Formative times to serve as the base for a site that was to become the Zapotec people’s most important capital. Prior to that time, the Early Formative ancestral Zapotec had lived in scattered villages and at least one centre of some importance, San José Mogote. San José Mogote shows evidence of Olmec trade and contacts dating to the time of San Lorenzo.

At Monte Albán, during the earliest, or Monte Albán I, epoch of that site’s history, a peculiar group of reliefs was carved on stone slabs and affixed to the front of a rubble-faced platform mound and around a contiguous court. The reliefs are usually called danzantes, a name derived from the notion that they represent human figures in dance postures. Actually, almost all of the danzante sculptures show Olmecoid men in strange, rubbery postures as though they were swimming in honey. From their open mouths and closed eyes, it is assumed that they are meant to represent dead persons. On many danzantes one or more unreadable hieroglyphs appear near the heads of the figures, most likely standing for the names of the sacrificed lords of groups beaten in combat by the Zapotec. Several slabs also bear calendrical notations, and it can be stated that the Middle Formative elite of Monte Albán were the first in Mesoamerica to develop writing and the calendar (at least in written form).

The Valley of Mexico in the Middle Formative

The cultures of central Mexico tended to lag behind those of southern Mexico in the development of political and religious complexity. The presence of Olmec figurines and ceramics in Early Formative burials in the Valley of Mexico has been noted, but the local communities of that time were of a modest village sort, as were those of the succeeding Middle Formative. On the western shores of the great lake filling the Valley of Mexico, for instance, remains of several simple villages have been uncovered that must have been not unlike small settlements that can be found in the Mexican hinterland today. The people who lived at El Arbolillo and Zacatenco had simply terraced off village refuse to make platforms on which their pole-and-thatch houses were built. Metates and manos are plentiful; pottery is relatively plain—featuring the abundant hard, white-slipped ware of the Middle Formative—and small female figurines are present by the thousands. Subsistence was based upon corn farming and upon hunting. In some Middle Formative sites, however, such as Tlatilco, there is evidence of Olmec influence, as in the previous Early Formative Period. There are also indications that ceremonial pyramid construction began in the latter part of the Middle Formative at Cuicuilco, a site in the southern part of the valley, which was to become a major centre in the succeeding Late Formative Period.

The Maya in the Middle Formative

In the Maya highlands, the key archaeological region has always been the broad, fertile Valley of Guatemala around present-day Guatemala City. The earliest occupation is known as the Arevalo phase, a village culture of the Early to Middle Formative. It was followed by Las Charcas, a Middle Formative culture known largely from the contents of bottle-shaped pits found dug into the subsoil on the western edge of the modern city. Extremely fine ceramics have been excavated from them, including red-on-white bowls with animal figures, effigy vessels, three-footed cups, and peculiar three-pronged incense burners. Solid female figurines are also present.

The earliest Middle Formative cultures of the Maya lowlands are called, collectively, the Xe horizon. They apparently developed from antecedent Early Formative cultures of the Maya lowlands that have been discussed above. The problem of the origin of the Mayan-speaking people has not been solved. It may be that they were Olmec people who had been forced out of their homeland to the west by the collapse of San Lorenzo. There were already peoples in the Maya lowlands in Early Formative times, however, and if the early Maya were Olmec, they brought little of their Olmec culture with them. Another hypothesis is that the earliest Maya descended to their lowland homelands from the Guatemalan highlands.

In the Maya lowlands the Mamom cultures developed out of those of Xe times. Mamom shares many similarities with the highland Maya at Las Charcas: pottery is almost entirely monochrome—red, orange, black, and white—and figurines are female with the usual punched and appliquéd embellishments. Toward the end of the Middle Formative, or after about 600 bce, Mamom peoples began building small ceremonial centres and modest-sized pyramidal platforms.
