THE OLMECS (1200 B.C. – 600 A.D.) ▪ The Olmec lived along the Gulf Coast of modern-day Mexico in tropical rain forests and lowlands from around 1200 BCE to 400 BCE. ▪ Both the Maya and the Aztecs were influenced by the Olmec civilization, the earliest known civilization in Mesoamerica. ▪ The Olmec are known for the immense stone heads they carved from a volcanic rock called basalt. Archaeological evidence also suggests that they originated the Mesoamerican practices of the Mesoamerican Ballgame—a popular game in the pre-Columbian Americas played with balls made from solid rubber—and that they may have practiced ritual bloodletting.

Olmec Cities and Trading Olmec prosperity was initially based on exploiting the fertile and well-watered coastal areas of the Gulf of Mexico to grow such crops as corn and beans (often twice-yearly) which allowed for an agricultural surplus. By c. 1200 BCE significant urban centers developed at San Lorenzo (the earliest), La Venta, Laguna de los Cerros, Tres Zapotes and Las Limas. San Lorenzo reached its peak of prosperity and influence between 1200 and 900 BCE when its strategic position safe from flooding allowed it to control local trade. The three sites of San Lorenzo, La Venta and Principal Olmec Settlements Laguna de los Cerros all had a bilateral symmetry in their planning and at La Venta the first pyramid in Mesoamerica was constructed.

Trading helped the Olmec build their urban centers of San Lorenzo and La Venta. These cities, however, were used predominantly for ceremonial purposes and elite activity; most people lived in small villages. Individual homes had a lean-to—sort of like a garage shed—and a storage pit for storing root vegetables nearby. They also likely had gardens in which the Olmec would grow medicinal herbs and small crops, like sunflowers.

Olmec Religion Religion has become the unifying force of each civilization that thrive in Mesoamerican region and for the Olmecs, it serves as an energy that bind them as one to their ruler and to the Gods that they believe into. There are no direct written accounts of Olmec beliefs, but their notable artwork provide clues about their life and religion. There were eight different androgynous—possessing male and female characteristics— Olmec deities, each with its own distinct characteristics. For example, the Bird Monster was depicted as a harpy eagle associated with rulership. The Olmec Dragon was shown with flame eyebrows, a bulbous nose, and bifurcated tongue. Deities often represented a natural element and included the following: The Maize deity Surviving art, like this The Rain Spirit or Were-Jaguar relief of a king or chief found in La The Fish or Shark Monster Venta, help provide clues about how Religious activities regarding these Olmec society deities probably included the elite functioned. rulers, shamans, and possibly a priest class making offerings at religious sites in La Venta and San Lorenzo.

Crafted in a variety of materials—jade, clay, basalt, and greenstone, which is an archaeologist's term for carved, green-colored minerals—much Olmec art is naturalistic. Other art expresses fantastic anthropomorphic—human-shaped— creatures, often highly stylized, using an iconography reflective of a religious meaning. Common motifs include downturned mouths and cleft heads, both of which are seen in Olmec hollow baby figurine. Realistic ceramic objects, such as this portrayal of an infant, illustrate representations of were-jaguars and the rain the highly skilled artistic style of the Olmec culture. deity.

Archaeologists speculate that the depopulation was caused by environmental changes, specifically by the silting-up of rivers, which choked off the E. The End of water supply. the Olmecs Another theory for the considerable population drop proposes relocation of settlements due to increased volcanic activity as the cause rather than extinction. Volcanic eruptions during the Early, Late, and Terminal Formative periods would have blanketed the lands with ash and forced the Olmec to move their settlements.

Including the areas that are today Belize, El Salvador, Guatemala, and Honduras. ▪ They were an agriculture-based society. They grow corn, beans, and squash, and practice many of the same crafts, such as weaving and pottery. ▪ Their central location made it very easy for the Map of the ancient Mayan civilization Maya to trade and interact with other cultures from North and South America.

The numerals consisted of only three symbols: zero, represented as a shell shape; one, a dot; and five, a bar. Thus, addition and subtraction was a relatively simple matter of adding up dots and bars. After the number 19, larger numbers were written in a kind of vertical place value format using powers of 20: 1, 20, 400, 8000, 160000, etc (see image on the right), although in their calendar calculations they gave the third position a value of 360 instead of 400 (higher positions revert to multiples of 20).

The Mayans formalized their language into a codified writing system. Their glyphs were used much like those of A glyph found in one of Mayan temple ruins Ancient Egypt, to represent words, sounds, and syllables through the use of pictures and other symbols. The Mayans used around 700 glyphs to do this and, incredibly, 80% of their language can still be understood by their descendants today. The Mayans also developed a form of an early book that recorded the exploits of their gods, daily life, news and many more subjects.

The Mayan Architecture ▪ The Mayan built towering temples, pyramids, plazas and palaces around the empire. ▪ The ceremonial centers usually consisted of pyramidal mounds with temples or other buildings on top. On top of the temples, priests performed religious ceremonies and sacrifices while people watched from the plazas below ▪ These structures were grouped together around an open plaza. The core of the structures was built of stone rubble and lime concrete. The exterior facade was faced with finished limestone blocks or stucco. Carved wood was used for door lintels. A corbel-like vault was developed that required very heavy walls and narrow interior spaces. Windows, if present at all, were very small. Both the interior and exterior walls were colorfully painted. Many of the structures acted as astronomical markers to track the movement of the heavenly bodies. PERSONAL PROPERTY OF JEFFREY ROMERO-GEC108, 1ST SEM 2020-2021 MSU-GSC B.1. Pyramid at Chichén Itzá The Maya incorporated their advanced understanding of astronomy into their temples and other religious structures. The pyramid at Chichén Itzá in Mexico, for example, is situated according to the sun’s location during the spring and fall equinoxes. At sunset on these two days, the pyramid casts a shadow on itself that aligns with a El Castillo (the Castle), Chichen Itza, carving of the head of the Mayan Yucatan, Mexico. 9th-13th century. serpent god.

Sayil Palace (600-900 A.D) Ruins of Sayil Palce at Puuc Route south of Merida in the western Yucatan, Mexico Sayil Palace is one of the oldest palaces in Maya history. The palace is a three-story building with each story set back from the one below. Instead of stacking the rooms one above the other, they were built side by side. The whole palace was made from stone and concrete in the Puuc architectural style. The building known as El Mirador on the site is believed to have been used as an observatory.

Temple of Inscriptions (A.D. 675-A.D. 683) The Temple of the Inscriptions is the largest stepped pyramid in the region, situated in the heart of Palenque. It was built to commemorate the ruler K’inich Janaab’ Pakal. It is one of the best sources of archeological information of the Maya civilization with the inscriptions on its walls telling us much about this great civilization. It has five entrances at the front with carved walls, and the staircase was built to reach the crypt situated at a higher level. Various tablets have been found in the temple which tell us how the Maya understood The Temple of Inscriptions, Palenque, Mexico. the notion of time.

The games had their own rules and regulations where two teams tried to bounce a rubber ball through a ring without using their arms and legs. The ball court usually had sloping sides, but in Uxmal, the sides were vertical; in Tikal, the court was a triple court and the walls were L-shaped. The ball games were believed to be based on religion, and the courts were built with their sacred nature in mind. The games were played One of the walls and goals of the ball court in from north to south, and the loser of the game the Maya-Toltec cityof Chichen Itza. 1050-1200 CE. had to make a sacrifice to the gods.

The Maya Religion High priests The Maya were deeply religious, and performing worshiped various gods related to nature, religious rituals including the gods of the sun, the moon, rain and corn. At the top of Maya society were the kings, or “kuhul ajaw” (holy lords), who claimed to be related to gods and followed a hereditary succession.

The Mayan Agriculture Although somewhat limited by their geographical location and local plant species, Mayan farmers were expert agriculturists. Their main crop staples included Corn (maize) but they also cultivated beans and squash, which were often grown together with corn to provide mutual support for each crop. As their population grow there is a need to double up their production of crops thus this factor drives the Mayans to mass produce the crops they have been utilizing to withstand the growing population of the empire. Some of the crops cultivated by the Maya PERSONAL PROPERTY OF JEFFREY ROMERO-GEC108, 1ST SEM 2020-2021 MSU-GSC  31 Recent discoveries also indicate Mayan farmers grew manioc (cassava), a highly nutritious and energy-rich root vegetable and an excellent source of carbohydrate. It turns out that their cultivation of cassava might solve a long-standing mystery as to how they were able to sustain such a large civilization and population given their lack of metal tools and locale. The Mayans were highly accomplished engineers and employed their skills to develop innovative farming techniques including raised farm beds and terrace farming. These techniques were vitally important in providing means of reducing water runoff and erosion and turning mountainous regions into productive farmlands.  32 D.1. The Rubber  Another unusual Mayan crop was rubber.  The Maya cut slits in the bark of the rubber tree and collected its sap. They used the dried sap to make water-resistant shoes and clothing.  Rubber was also used to make balls. The Maya played games in enclosed, I-shaped courts with the rubber balls. These ball games took on a ritual significance and were an important part of Mayan culture.

Medicinal activities tended to be practised by priests who inherited their positions and received extensive training. For the Mayans, health and ill-health was a matter of balance and imbalance. Balance equalled health and imbalance sickness. They believed this was always controlled by the diet, gender, and age of a person. They knew about stitches and often used human hair to suture wounds. They also regularly made casts to speed the healing and recovery of fractures and other bone breakages. By all accounts, they were particularly skilled at dentistry and used iron pyrite as tooth fillings. Mayan 'witch doctors' were also skilled in creating prosthetics made from jade and turquoise and used obsidian for making cuts. Obsidian is noted for its near-monomolecular edge whose use, when compared to other materials, has the ability to accelerate healing and reduce scarring. It is still in use today by some surgeons performing specialist operations. The Mayans also had extensive knowledge of their local plant ecosystem and used over 1500 different plants to treat a variety of ailments. PERSONAL PROPERTY OF JEFFREY ROMERO-GEC108, 1ST SEM 2020-2021 MSU-GSC  35 Despite the Maya’s remarkable scientific achievements, their culture began to decline toward the beginning of the 11th century. Cause of the civilizations decline are as follows: Maya were wiped out by war; F. The Decline of the Maya Disruption of their trade routes; Maya’s agricultural practices and dynamic growth resulted in climate change and deforestation; Maya culture was subsumed by the Spanish conquistadors in the 16th century.

Sustainable Agriculture: The Aztec Way ▪ The Aztecs were the first to develop the “floating gardens.” Later, it was given a name called “chinampas.” ▪ Chinampas are artificial islands that were created by interweaving reeds with stakes beneath the lake's surface, creating underwater fences. A buildup of soil and aquatic vegetation would be piled into these "fences" until the top layer of soil was visible on the water's surface. ▪ These agricultural lands received this nickname due to the illusion they caused. The bodies of land appeared to be "floating" on the water because the canals surrounded the chinampa plots.

Aztec Canoe Aztecs has developed special boats called canoes which made transportation through streams and rivers easier. This mode of transportation was thus extensively used throughout the Aztec Empire. They dug many small canals for the transportation of canoes. The Aztec canoe Average size of a is 14 feet in length, were dug used for out from a single tree trunk and had upturned transportation ends. They were propelled by wooden pole or paddle. It took about a week for a skilled carpenter to make a canoe, and it could cost the equivalent in the market of a single fine cotton cape.

The Aztec Architecture The Aztec Empire is famous for many of its features including the amazing architectural styles that the Aztec people used in the construction of their buildings and cities. Aztec architecture followed similar principles to other earlier Mesoamerican civilizations, including, the use of a grid system in city building and the construction of large temples in the shape of a pyramid. The Teotihuacan pyramids are some of the largest of their kind in the Americas. Ancient Pyramids at Teotihuacan a vast Mexican archaeological Teotihuacanos constructed the Pyramid of complex northeast of Mexico City. the Sun and the Pyramid of the Moon in the year 100 C.E., centuries before the Aztec had arrived in Teotihuacan.

Aztecs Calendar and Dates The Aztec's system of tracking days was very intricate and their calendar system was derived from the Mayan one. The Aztec people followed two main calendars. One was a more sacred calendar consisting of 13 months of 20 days, while the other was an agricultural or solar calendar with 18 months of 20 days. The solar calendar, being the scientific one, should add up to 365 days, yet it only adds up 360. The Aztec sunstone, a very famous calendar, weighs 24 tons and is 13 feet in diameter.

Aztecs Hieroglyphs The Aztecs language was called Classical Nahuatl and it wasn't written as an alphabet but as a series of glyphs. Each symbol represented only one sound. The language of the Aztecs were eventually developed into an alphabet, yet they used to simply be a series of pictures used in three different ways. The first way was pictograms. This was simply about the symbol meaning what it looked like. This method was easy understand but it required hundreds and thousands of symbols to have meaningful language. The second way is ideograms. Ideograms are related to idea behind what the symbol represents. A picture of footprints could represent a trip or even a passage of time in a certain direction. The last way is phonograms. This is finally how a picture can represent a certain sound such as a picture of a bee could represent the sound of "b". All these components came together in the Aztec glyphs.

In order to tell a story, there wasn't a line of several glyphs but rather a few colorful glyphs positioned properly. PERSONAL PROPERTY OF JEFFREY ROMERO-GEC108, 1ST SEM 2020-2021 MSU-GSC  51 G. Aztec Math and Number System Aztec number system was a vigesimal one, which means they used 20 as a base number. In their arithmetic calculations, there were symbols that were used to represent different values. A dot meant the number 1, a bar meant 5, and there were many other symbols for 20 and its various multiples. It was also clear that the Aztecs had a very clear understanding of multiplication and division in the sense of geometry. Their standard unit of linear measurement was called land rod, equivalent to 2.5 meters. If an object was not an exact amount of land rods, certain symbols were added to indicate the remaining length (less than a land rod). These symbols were related to body parts as the human body was very well understood. For example, the This map from 1540 heart symbol would represent a similar has notations in Aztec length to the distance between one's numbers depicting fingertip and heart. The hand symbol dimensions of lands would stand for an identical length of near Texcoco, the the distance from one's right fingertip ancient capital of the and one's left fingertip. Acolhua Aztecs.

They decided to make it mandatory for children to attend school and receive education. Aztec Calmecac From age 12 to 15, kids attended a type of school from Florentine called cuicalli, also known as house of song. This was a Codex place where they learned ceremonial songs and the cosmology of their people. Most girls ended their education there at age 15, however boys went to a type of school called telpochalli from ages 15 to 20. Aztec Telpochcalli from They slept at this school, but if that wasn't an option the Florentine Codex boys went to another type called calmécac. Calmécac taught of a variety of subjects as well as trained them for the military as the school offered opportunities for a government position.

THE INCA (1438 A.D. – 1533 A.D.) The Inca civilization flourished in ancient Peru between c. 1400 and 1533 CE, and their empire eventually extended across western South America from Quito in the north to Santiago in the south, making it the largest empire ever seen in the Americas and the largest in the world at that time. the Incas conquered people and exploited landscapes in such diverse settings as plains, mountains, deserts, and tropical jungle. Famed for their unique art and architecture, they constructed finely-built and imposing buildings wherever they conquered, and their spectacular adaptation of natural landscapes with terracing, highways, and Map of the Inca empire mountaintop settlements continues to impress modern visitors at such world famous sites as Machu Picchu.

It was a monarchy ruled by a single leader called the Sapa Inca. Sapa Inca - The emperor or king of the Inca Empire was called the Sapa Inca, which means "sole ruler". He was the most powerful person in the land and everyone else reported to the Sapa Inca. His principal wife, the queen, was called the coya. A.1. Inca Government Organization Viceroy - Below the Sapa Inca was the viceroy, or Inkap Rantin. He was a close relative of the Sapa Inca and worked as his closest advisor. High Priest - The high priest, called the "Willaq Umu", was also a very powerful man. He was probably second in power to the Sapa Inca due to the importance of religion in the Inca Empire. Governors of a Quarter - The Inca Empire was divided up into four quarters. Each of these quarters was ruled by a governor called an Apu. Council of the Realm - The Sapa Inca also kept a council of men who advised him on major matters. These men were powerful nobles. Inspectors - In order to maintain control and to make sure people were paying their taxes and following the ways of the Inca, the Sapa Inca had inspectors that watched over the people. The inspectors were called "tokoyrikoq". Military Generals - There were also military generals. The head general was usually a close relative of the Sapa Inca. These leaders were called "Apukuna". Other Officials - There were many other government officials and leaders throughout the Inca Empire such as priests, military officers, judges, and tax collectors.

The Inca Tax For tax purposes censuses were taken and populations divided up into groups based on multiples of ten (Inca mathematics was almost identical to the system we use today). As there was no currency in the Inca world, taxes were paid in kind - usually foodstuffs, precious metals, textiles, exotic feathers, dyes, and spondylus shell - but also in labourers who could be shifted about the empire to be used where they were most needed, known as mit'a service. To keep track of all these statistics, the Inca used the quipu, a sophisticated assembly of knots and strings which was also highly transportable and could record decimals up to 10,000.

Inca Architecture Master stone masons, the Incas constructed large buildings, walls and fortifications using finely-worked blocks - either regular or polygonal - which fitted together so precisely no mortar was needed. With an emphasis on clean lines, trapezoid shapes, and incorporating natural features into these buildings, they have easily withstood the powerful earthquakes which frequently hit the region. The distinctive sloping trapezoid form and fine Inca 12 Angle Stone masonry of Inca buildings were, besides their obvious aesthetic value, also used as a recognisable symbol of Inca domination throughout the empire.

Inca Road System The Inca Empire was connected by its vast road system (running 25,000 miles), which made Inca road communication between even far away points system located possible within days. Messengers lived in pairs – and At the Andes their whole responsibility was to be ready to receive mountain range a message and run to deliver it – so one of them would sleep while the other remained ready to do the job. With the road system and messenger service, the king could send out an order to mobilize an army for defense and the men of the various communities would respond in a timely fashion. There were stations, inns, and storage depots along this roadway to supply troops, give travelers a rest, and maintain those who worked for the messenger services.

As they were built in different geographical zones using local populations, the roads are, consequently, not uniform in construction design or materials. Sometimes there are also two or three roads constructed in parallel, especially near the larger urban centres.

Roads were typically edged and protected with small stone walls, stone markers, wooden or cane posts, or piles of stones. Drainage was provided by frequent drains and culverts, which drew off rainwater from the road surface, channelling it either along or under the road. When crossing wetlands, roads were often supported by buttress walls or built on causeways.

Inca Food & Agriculture The Inca state developed a huge farming apparatus, where crops and herds were commandeered from conquered people and the people themselves were periodically commandeered to work on state-owned farms. More positively, a vast network of storage facilities was developed to insure against times of drought and disaster and foodstuffs were often given out as gifts by rulers seeking to make themselves popular. Land was worked using simple tools such as a hoe, clod breaker, and foot plough - the chakitaqlla, which consisted of a wooden or bronze pointed pole that was pushed into An Inca circular terracing used to increase agricultural the ground by placing one's foot on a yield.

Livestock was primarily llama and alpaca herds. These animals were vital to many aspects of Andean life as they provided wool, meat, leather, moveable wealth, transportation - especially for the army, and they were often sacrificed in religious ceremonies. The Incas were ambitious farmers, and to maximise agricultural production, they transformed the landscape with terracing, canals, and irrigation networks, whilst wetlands were often drained to make them suitable for Some of Inca cultivated crops farming.
