"People who are anxious to bring on war don't know what they are bargaining for; they don't see all the horrors that must accompany such an event."

--Lt. General Thomas J. "Stonewall" Jackson

"Captain Smith sprang to his side, and as he raised his head a bright beam of moonlight made its way through the thick foliage and rested upon the pale face of the sufferer. The captain was startled by its great pallor and stillness, and cried out: "Oh! General, are you seriously hurt?"

"No," he answered, "don't trouble yourself, my friend, about me;" [17]

Mayan Ruins as Seen From Space

Mayan ruins were spotted in the dense forest from space.

Urban design

As Maya cities spread throughout the varied geography of Mesoamerica, site planning appears to have been minimal. Maya architecture tended to integrate a great degree of natural features, and their cities were built somewhat haphazardly as dictated by the topography of each independent location. For instance, some cities on the flat limestone plains of the northern Yucat√°n grew into great sprawling municipalities, while others built in the hills of Usumacinta utilized the natural loft of the topography to raise their towers and temples to impressive heights. However, some semblance of order, as required by any large city, still prevailed.

Classic Era Maya urban design could easily be described as the division of space by great monuments and causeways. Open public plazas were the gathering places for people and the focus of urban design, while interior space was entirely secondary. Only in the Late Post-Classic era did the great Maya cities develop into more fortress-like defensive structures that lacked, for the most part, the large and numerous plazas of the Classic.

At the onset of large-scale construction during the Classic Era, a predetermined axis was typically established in a cardinal direction. Depending on the location of natural resources such as fresh-water wells, or cenotes, the city grew by using sacbeob (causeways) to connect great plazas with the numerous platforms that created the sub-structure for nearly all Maya buildings. As more structures were added and existing structures re-built or remodeled, the great Maya cities seemed to take on an almost random identity that contrasted sharply with other great Mesoamerican cities such as Teotihuacan and its rigid grid-like construction.

At the heart of the Maya city were large plazas surrounded by the most important governmental and religious buildings, such as the royal acropolis, great pyramid temples and occasionally ball-courts. Though city layouts evolved as nature dictated, careful attention was placed on the directional orientation of temples and observatories so that they were constructed in accordance with Maya interpretation of the orbits of the heavenly bodies. Immediately outside of this ritual center were the structures of lesser nobles, smaller temples, and individual shrines; the less sacred and less important structures had a greater degree of privacy. Outside of the constantly evolving urban core were the less permanent and more modest homes of the common people.

Building materials

A surprising aspect of the great Maya structures is their lack of many advanced technologies seemingly necessary for such constructions. Lacking draft animals necessary for wheel-based modes of transportation, metal tools and even pulleys, Maya architecture required abundant manpower. Yet, beyond this enormous requirement, the remaining materials seem to have been readily available. All stone for Maya structures appears to have been taken from local quarries. They most often used limestone which remained pliable enough to be worked with stone tools while being quarried and only hardened once removed from its bed. In addition to the structural use of limestone, much of their mortar consisted of crushed, burnt and mixed limestone that mimicked the properties of cement and was used as widely for stucco finishing as it was for mortar. Later improvements in quarrying techniques reduced the necessity for this limestone-stucco as the stones began to fit quite perfectly, yet it remained a crucial element in some post and lintel roofs. In the case of the common Maya houses, wooden poles, adobe and thatch were the primary materials; however, instances of what appear to be common houses of limestone have been discovered as well. Also notable throughout Maya architecture is the corbel arch (also known as a "false arch"), whose limitations kept their structures generally weighty rather than airy.

Notable constructions

  • Ceremonial platforms were commonly limestone platforms of typically less than four meters in height where public ceremonies and religious rites were performed. Constructed in the fashion of a typical foundation platform, these were often accented by carved figures, altars and perhaps tzompantli, a stake used to display the heads of victims or defeated Mesoamerican ballgame opponents.
  • Palaces were large and often highly decorated, and usually sat close to the center of a city and housed the population's elite. Any exceedingly large royal palace, or one consisting of many chambers on different levels might be referred to as an acropolis. However, often these were one-story and consisted of many small chambers and typically at least one interior courtyard; these structures appear to take into account the needed functionality required of a residence, as well as the decoration required for their inhabitants stature.
  • E-Groups are specific structural configurations present at a number of centers in the Maya area. These complexes are oriented and aligned according to specific astronomical events (primarily the sun’s solstices and equinoxes) and are thought to have been observatories. These structures are usually accompanied by iconographic reliefs that tie astronomical observation into general Maya mythology. The structural complex is named for Group E at Uaxactun, the first documented in Mesoamerica.

  • Pyramids and temples. Often the most important religious temples sat atop the towering Maya pyramids, presumably as the closest place to the heavens. While recent discoveries point toward the extensive use of pyramids as tombs, the temples themselves seem to rarely, if ever, contain burials. Residing atop the pyramids, some of over two-hundred feet, such as that at El Mirador, the temples were impressive and decorated structures themselves. Commonly topped with a roof comb, or superficial grandiose wall, these temples might have served as a type of propaganda. As they were often the only structure in a Maya city to exceed the height of the surrounding jungle, the roof combs atop the temples were often carved with representations of rulers that could be seen from vast distances.
  • Observatories. The Maya were keen astronomers and had mapped out the phases of celestial objects, especially the Moon and Venus. Many temples have doorways and other features aligning to celestial events. Round temples, often dedicated to Kukulcan, are perhaps those most often described as "observatories" by modern ruin tour-guides, but there is no evidence that they were so used exclusively, and temple pyramids of other shapes may well have been used for observation as well.
  • Ball courts. As an integral aspect of the Mesoamerican lifestyle, the courts for their ritual ball-game were constructed throughout the Maya realm and often on a grand scale. Enclosed on two sides by stepped ramps that led to ceremonial platforms or small temples, the ball court itself was of a capital "I" shape and could be found in all but the smallest of Maya cities.

16th century Missionary burns Mayan Texts (This is a fairly advanced read)

When Diego de Landa burned the books of the Maya in the 16th century, the Spanish Roman Catholic inquisitor thought he could wipe out Indigenous memory. By destroying long sheets of bark paper, he thought he could destroy knowledge conveyed in signs and images that spoke of dreams and wars and people born before Christ, of the movements of stars and frequency of eclipses, of the respect for God in nature necessary to call for timely rain and good corn harvests.

Yet Diego de Landa, in his zeal to destroy what he deemed idolatry, was mistaken. The faith of the Maya wasn't bound in those primitive codices he turned to ash.

Evidence that he ultimately failed can be found every morning throughout the Indigenous highlands of Guatemala and southern Mexico, where Maya farmers rise from their sleep to thank father sun and mother earth for another day.

Though Diego de Landa failed in his campaign against paganism, he shouldn't be forgotten. To write about interfaith relations in Guatemala today leads back to the first encounter between two worlds -- the violence and ethnocide that followed quickly upon Christopher Columbus' journeys to what Europeans called the New World.

Although Diego de Landa, a Franciscan priest, was a fanatic who had his share of Spanish critics, his naming as a bishop shortly after his book-burning rampage indicates he carried out imperial and ecclesiastical policy. It was clearly a period of history marked by fear and arrogance, European sins for which millions of Maya paid with their lives.

By tearing down Maya altars or building their Roman Catholic churches on top of the Indians' sacred sites, and forcing the Maya to convert to Christianity or perish, the Spanish engaged in what some historians call a sacramentalization of Indigenous culture, as opposed to an authentic process of evangelization that seeks to express Gospel values within a culture.

Imposing Christian beliefs produced generations of Maya who became Christians to survive, who went to mass but in their hearts still felt the presence of the sacred altars below the cathedral floor, who practiced what became a syncretic faith mixing their ancestors' faith with elements of the colonial master's religion.
