MEXICAN PEOPLES The Nahuatl-speaking Peoples.—In this section the centre of interest is the Valley of Mexico, where Mexico City (Tenoch titlan) was, at the time of the Conquest, the seat of Aztec power. Excavation, principally at Azcapotzalco, has demonstrated that the earliest remains show close affinity with those of the Huaxtec region, of the Tarascan area (in Guadalajara), and with certain archaic pottery found in the Maya district. Superimposed are objects which can be related with the Toltec, which exhibit a close relation to Maya art of the finer period. Above these are the inferior relics of the Aztec regime. So far these results sug gest that a common culture, based on agricultural life (with maize as the staple plant), extended throughout. The development of Maya culture in the south had very far-reaching effects upon the Mexican Valley, the Zapotec tribes of Oaxaca acting as inter mediaries. The successive waves of Nahuatl-speaking tribes, im migrants from the north (fundamentally hunters) adopted this culture when they became sedentary and developed it, though in rather degraded form, according to their own psychology. In brief, the history of the Nahuatl, summarized from legends col lected by the early chroniclers (such as Sahagun and Ixtlilxochitl) supplemented by native pictographical manuscripts, appears to be as set out in the accompanying chronological table. This table, taken from Joyce's Mexican Archaeology, is explained in detail in that work. The first wave Qf immigrants appears to have been constituted by the people known to history as Toltec, who, establishing themselves at the "city" of Tulan, gradually ex tended their power over the Valley of Mexico, and absorbed, to the best of their ability, those elements of early Maya culture which had percolated to that region. Three centuries of develop ment followed, during which arts and crafts were brought to a high pitch of perfection. So that, when eventually the Toltec "empire" collapsed under further pressure of hunting tribes from the north, the name of the Toltec survived in tradition as the great exponents of culture. The generic name given to these later immigrants is "Chichimec." Like the Toltec, they were speakers of the Nahuatl tongue, and the name survived in Aztec times as applied to the rude hunting-tribes on the northern borders, who still lived under the primitive conditions which characterized the earliest Nahuatl immigrants. The terminology is confusing, because in the widest sense the term Chichimec is equivalent to Nahuatl ; in the narrower sense it applies to that branch of Nahuatl who settled at Tenayocan, under the "Chichi mec" chief Xolotl, at the time of the Toltec downfall, and who appear to have exercised a loose suzerainty over the remaining Toltec, whose legitimate ruler had moved to Colhuacan. The population of this settlement were termed "Acolhua," but the term was later expanded to include all those "Chichimec" who adopted settled life.
The "Chichimec" (using the word in the narrower sense) in course of time transferred their seat of power to Tezcoco. The next wave of immigration, the Tepanec, settled at Azcapotzalco and later at Tlacopan. The final wave, the Aztec, after some years spent in subordination to the earlier immigrants, finally established themselves on the islands of Tenochtitlan and Tlalte lolco in the Lake of Mexico, and eventually became rulers, not only of the Valley, but suzerains of countries far to the south. (For details see Bibliography, Joyce.) The break-up of the Toltec "empire" led to a whole-sale emi gration of Toltec clans, which had far-reaching effects on the populations to the south and east, resulting in the introduction of Toltec art into Yucatan and Salvador. Further pressure sent Nahuatl influence further afield, with the result that, at the time of the Conquest, tribes speaking Nahuatl were found in Nica ragua (Rivas) and even in Panama (Chiriqui Lagoon). It seems certain that the Nahuatl were responsible for the introduction of the bow into the areas previously dominated by Maya culture, and this weapon no doubt facilitated their progress as conquerors. There is no trace of the bow among the early Maya, but refer ences occur in the tribal legends of the Quiche (Popol Vuli) and Kakchiquel (Annals of Xahila) in the region of Lake Atitlan in Guatemala; and the bow was the weapon of the immigrant aristocracy in Yucatan at the time of the Conquest. Further, the Aztec historical manuscripts show, in pictographic form, the immigrant Aztec, skin-clad and armed with the bow, overcoming the valley-dwellers clothed in cotton garments but armed only with the inacquauitl, a wooden club edged with obsidian.
Settled on their islands in the Lake of Mexico, for a century the Aztec played an unimportant part in the politics of the Mexican Valley. But under their fourth historical ruler, Itzcoatl, in the early part of the i 5th century, owing to intertribal con flicts, they rose to prominence. A league was formed between Tenochtitlan (including Tlaltelolco), the Acolhua settlement of Tezcoco, and the Tepanec settlement at Tlacopan, and this con federation endured until the Conquest. The Aztec reserved for themselves the direction of the military policy of the confedera tion, and thereby became the paramount power, owing to the in timate connection of war with religion. Tezcoco, however, was, to the end, regarded as the seat of learning and culture, the Mexican "Athens." One settlement alone held its independence, the "city" of Tlaxcala, where Toltec traditions still survived. Though the league maintained continual hostilities against the Tlaxcalans, no very serious effort appears to have been made to conquer them, owing to the ceremonial nature of Mexican war fare as explained below. The long-enduring hostility felt by the Tlaxcalans for the Aztec led them to ally themselves with the Spaniards to whom they gave invaluable assistance.
The final step in the consolidation of the Aztec "Empire" was the incorporation of the island of Tlaltelolco, which had previ ously been ruled by its own chiefs, with that of Tenochtitlan. This occurred in 1473, when Axayacatl attacked Tlaltelolco, killed the ruler Moquiuix and incorporated the smaller island with Tenochtitlan. Axayacatl, by means of various expeditions, extended Aztec influence far beyond the confines of the Valley, and his policy of expansion was continued by his successors. Such expeditions were not conquests in the normal sense of the word, owing to the Mexican attitude towards war; but they re sulted eventually in a complex system of trade and tribute, extend ing from the Panuco River to Central Guatemala. The "tribute lists" of the Mexican ms. known as the Codex Mendoza (preserved in the Bodleian Library at Oxford) shows the enormous extent of territory from which Mexico City drew "tribute" at the time of the Conquest.
Of Aztec buildings, little trace has remained. The two great pyramids of Tenochtitlan and Tlaltelolco, each supporting two shrines, were utterly destroyed by the Conquistadores, but con temporary accounts suggest that they were built on the Toltec model, i.e., stepped pyramids, with a stairway on the west. As regards the shrines, native manuscripts suggest that they were small and flat-roofed, with an embattled pediment, or roof-comb, and built probably of wood. Cne sole survivor of Aztec religious architecture remains, in ruined form, at Teportlan and has been described by Seler. The same author has recorded buildings be longing to the Aztec period in the Huaxtec and Totonac settle ments of Papantla and Cempoala. Both here, and in Mexico City, stucco was freely used as a coating to masonry, and the facing of the Totonac buildings was so perfect that the spies sent in advance by Cortes, reported that they were faced with silver plates.
As regards secular buildings, the reports of the Conquistadores provide the only source of information. The houses of the upper class were built on terraces and constructed of stone. The build ings usually enclosed a court, where the girls of the household could walk under the supervision of duennas; and the roofs of the more important buildings were flat and battlemented. In fact there is little trace of the Maya false arch in Aztec buildings.
Less pretentious dwellings were constructed of sunbaked bricks (adobe), while the poorest class lived in flimsy structures of reeds and mud, roofed with straw of leaves of maguey.
A remarkable architectural achievement on the part of the Aztec was the series of causeways which connected the island with the mainland. In building them, a double palisade was first erected and the space between filled with earth and rubble and faced with stones. The great dam, which led from Iztapalapa to Atzacualco (built by Montecuzoma I. on the advice of Neza hualcoyotl of Tezcoco), was ten miles long, perforated by sluices and was erected in an attempt to control the inundations to which Tenochtitlan was subject. Another work of great economic im portance was a double stone aqueduct, which brought water to the city from Chapultepec.
Ceremonial cannibalism was an occasional feature of sacrifice, certain individuals being privileged to partake of the body of the victim. But the act was purely ritual, and, in fact, an act of corn munion, for which many parallels can be found in other parts of the world.
To Quetzalcoatl no human sacrifices were made, and, as it is clear that this god was originally adopted from the early Maya, further support is given to the theory that human offerings were introduced into Mexico by the Nahuatl immigrants.
The composite nature of Aztec religion is equally expressed in the method of disposing of the dead. Both cremation and in humation were practised, but the two methods bore a definite relation both to the method of death of the individual, and to the worship of certain gods. The fate of the soul varied accord ingly. Men killed in battle or by sacrifice reached the Paradise of the Sun; women dying in child-birth had a paradise of their own, because their death was considered a warrior-death. Persons who were drowned, or who perished of dropsical affections were accommodated in a separate paradise belonging to the pre-Aztec fertility- and rain-god Tlaloc. People dying normally had only the dim underworld of the death-god, Mictlantecuhtli, as their future abode. Cremation was the fate of all except those who were destined for Tlaloc's paradise. This fact affords a clear indication that inhumation was the early form of funerary rite, and that cremation was introduced by the Nahuatl immigrants. Much has been recorded on the subject of Mexican religion, the gods, their respective ritual and feast, their attributes and tribal affinities. For details see Bibliography under Sahagun, Seler and Joyce.
In their contest with the Spaniards the Mexicans were, in a sense, betrayed by their own religion. There was an ancient legend that the great culture-god, Quetzalcoatl, after instructing the people in the useful arts, departed eastward over the sea, promising to return in a year of a certain date. According to tradition, Quetzalcoatl was white-skinned and bearded and the arrival of the Spaniards, in the appropriate year, led Montecu zoma II., who had been trained as a priest, to adopt a fatally hesitating policy towards them. Again, the fact that the Aztec fought, not to kill, but to capture, on more than one occasion saved the small force of Cortez from annihilation.
Metal-working in Mexico was, in the main, confined to gold, and there were two separate "guilds" of gold-workers, the beaters and the casters. Casting was done by means of the "cire-perdue" method, and the same process was employed, especially by the Totonac, in dealing with copper, which, owing to the presence of a percentage of tin (as an impurity) was, in fact, an accidental bronze. Gold-foil, of extreme thinness, was produced by the beaters, and frequently applied to wood-carving. Many works of art, known to us by description, have perished in the melting pot being composed of a metal precious in European economy, with the result that Mexican gold-work is extremely rare in Museums. Wood was used both for building and in the manu facture of various utensils and instruments, especially gongs (teponaztli), but, owing to the perishable nature of the material, specimens are scarce (see Saville, Bibliography). The art of the potter flourished in Mexico, and though the wheel was unknown, certain classes of ware are remarkable for the perfection of their shape, firing and decoration. For the most part the coiling pro cess was employed, but the use of moulds was also known. The pottery of the Aztec is distinctly inferior from every point of view. Toltec ware shows close affinities with the Maya, but exhibits in the most characteristic examples a peculiar "cloisonne" technique, in which a dark slip, added to the surface of the pot has been cut out to form outlines, and slips of other colours, principally turquoise-blue, inlaid between them. Ware of this class is found in the Totonac area of Vera Cruz, and bears wit ness to the close association of the Totonac with Toltec culture. But such examples are rare, and as regards the two qualities of form and firing, Totonac pottery (of which the most notable series is preserved in the British Museum), represents the finest achieve ment of the Mexican potter. In colour and burnish, however, the pottery of Cholula (in the state of Puebla), and of the Zapotec, are paramount. The two classes of ceramic ware show very close similarities, and the colours employed are those of the finest Maya pottery. Puebla was peopled by clans of Toltec origin and the Zapotec country had been permeated by Maya influence. The inference is that the population of Puebla had received, through the Zapotec, the tradition of Maya colouration. In any case under the late Aztec regime, the potters of Cholula were regarded as the masters of the ceramic art, and the table-ware of Montecuzoma and the Aztec nobles was provided by this province.
Good pottery was manufactured also by the Huaxtec and Taras cans, the large figurines of the latter people showing conspicuous freedom and originality in modelling.
The textile art was developed to a high degree by means of a very simple form of loom. Patterns of the most intricate type were inwoven or embroidered, and one of the most important dyes was that produced by the cochineal insect, which consti tuted an important item of tribute to Mexico City. Very few Mexican textiles have survived, but the native mss. bear witness to the perfection of technique and brilliancy of colouring.
The art of feather-mosaic was extensively practised in Aztec times. Complicated designs were produced by the meticulous application of the small feathers of tropical birds to a background of cloth or maguey (aloe) paper. Practically all the surviving specimens relate to post-conquest times, when, under the influence of missionaries, numbers of sacred pictures were produced in this technique. Complicated arrangements of feathers, secured to a bamboo framework, were worn by warriors of different ranks attached to the back, and military standards were constructed of the same materials. Art can best be studied in Museums, or by means of well-illustrated books devoted to this subject (see Joyce, Bibliography). Toltec art shows a very close correspondence with that of the Maya, with a tendency to stylization in angular form. The flowing line was not lost, but the increased convention alism often gives to Toltec art a slightly "mechanical" aspect. In Aztec times the angularity is accentuated in the mss., but in sculp ture there is a great tendency towards simplification combined with a subtle suggestion of ferocity.

The inner social system of Mexico under Aztec domination provides all the features which might be expected from the in cursion of immigrants, who acquired land-interests, either by right of conquest or by intermarriage with the daughters of local chiefs. The conquering chiefs gave land to their principal re tainers, and these formed an aristocracy who paid no taxes but owed feudal service to the ruler. Associated with them was a military nobility, who held estates at the ruler's good-will, and whose tenants paid royal taxes. Next came a class of landed freemen, members of "clans," known as calpulli. These calpulli distributed the land over which they had rights among their members, but any member who, whether by carelessness or by change of abode, allowed his plot to go out of cultivation, lost his holding. The calpulli paid taxes in common. Below the free men ranked the tax-paying rent-holders, and, finally the serfs who paid taxes only to their feudal lords. Apart from these were the members of the official class and their families, who, ranking as warriors and "nobles," paid no taxes, but contributed their personal services, and formed the suite of the ruler. To provide for the education both of the artisan and upper classes full pro vision was made. The exercise of certain pursuits was in the hands of close corporations (mainly of different tribal stocks) ; but apart from technical specialists, provision was made for the "higher education" of children. The institution known as the Calmecac provided the education for those who desired to adopt a priestly career, and was under the especial protection of the god Quetzalcoatl, while the candidates for military service entered the Telpochcalli, where, under the aegis of the god Tezcatlipoca, they received a military training. Details of the Aztec constitution are readily available in the works of Sahagun, and the compilation of Joyce (see Bibliography).
In Nicaragua stone-building on the scale practised by the Maya and Aztec was unknown, but monolithic sculptures, some of considerable size, have been found on the islands in lakes Managua and Nicaragua. These are not Nahuatl in style, and are believed to have been the work of the Chorotega people, who probably occupied a wider area in ancient times than is indicated by later linguistic surveys. Archaeological evidence, slight as it is, suggests that their original territory was reduced by the expansion of the Matagalpa, Sumo and Ulua peoples. They manu factured good painted pottery, and it is quite possible that their art was a reflection of that of the Maya; but far more explora tion is necessary in Honduras before the connection can be proved. The Nicarao (or Niquirian) people in Rivas, were of comparatively late Nahuatl stock, but the pottery found in the area possesses finer qualities than that of the Aztec. Though stone-carving on a large scale is rare, yet the Nicaraguans and Northern Costa Ricans produced smaller examples of sculpture, in the form of figures, bowls and, especially, metates (tripod slabs for grinding maize). In the peninsula of Nicoya, jadeite was worked with great skill, and pendants in the Nicoyan style have been found in regions north and south of the district. Probably more worked jadeite has been recovered from Nicoyan ceme teries than anywhere else in America, yet the source of the material is still unknown. The Nicoyans represent a definite lin guistic unit to-day, but archaeological evidence proves, that in the heart of the peninsula was an enclave of Nahuatl immigrants, who manufactured pottery of extremely good technique (both as regards paste and coloured decoration) in which the Mexican tradition is obvious.
On the mainland, opposite the Nicoyan peninsula, is a strip of territory (in Costa Rica) occupied by the Guetar people whose ancient cemeteries have yielded quantities of polychrome pottery, which, though inferior in colour to that of Nicoya, and, again, inferior in quality of paste to that of the tribes to the south and east, nevertheless shows great variety and takes a high rank in the scale of primitive ceramics. In southern Costa Rica, and western Panama, inhabited for the most part by Talamancan tribes, the potter's art was developed to a degree which has its only parallel in Peru. In the quality of technique the so-called "biscuit-ware" of the Talamancans is unsurpassed in the history of hand-made pottery, and the sense of form exhibited in these vases is beyond reproach. In slip-decoration the brilliancy of colour is inferior to that of the ware of Cholula or Oaxaca, and, especially that of Southern Peru. But the Talamancans were masters of the so-called "lost colour" process, whereby elements of a design were "reserved" by wax-painting on a slip of a cer tain colour. Upon this a second slip of another colour was added, which, in the firing was released from the waxed portions. Pottery of this class is common in Colombia and Ecuador, and occasional in Peru, while its occurrence in the Isthmian region emphasizes the connection of the Talamancan region with the southern con tinent. Further evidence of this connection is provided by the gold-work, recovered in large quantities from Talamancan ceme teries. Pendants in human and animal form have been obtained in considerable bulk from this area. The raw material was ob tained by the laborious process of picking out grains of gold from river-sands, and the ornaments were partly cast (by the process), and finished by hammering. The same processes pre vailed in Colombia, and it is not easy to distinguish the products of the two regions. Between the Talamancan district and the southern continent lay a densely forested area, peopled by tribes of lower culture, but on the Pacific coast, especially in the gulf of San Miguel, the first Spanish explorers found settlements engaged in pearl-fishery and a coastal trade southwards. From a chief named Tumaco they received an itinerary by sea to Peru, then undiscovered, and an allusion, in vague terms, to the great Inca Empire. (See Joyce, Bibliography.) Inter-tribal traffic had attained a high degree of development in Central America. The jadeite work of Nicoya is found sporadi cally in southern Costa Rica, while the gold-work of the Tala mancan area has been discovered, not only in Nicoya, but even at Chichen Itza in Yucatan. The Isthmian region in every respect, flora, fauna and ethnography, combines the characteristics of both North and South America. Apart from the interchange of commercial products by hand-to-hand trade, Mexican influence from the north introduced the practice of cremation into certain restricted areas, where it impinged on certain technical processes (pottery and gold-work) characteristic of the Southern Continent.
