Volcano Yellowstone

Yellowstone Volcano is one of a series of active volcanoes located on the west coast of the United States. Mountains of fire in this region is part of a ring of fire thatsurrounds the Pacific Ocean, and into areas prone to earthquakes. YellowstoneVolcano storing wealth of flora, animal and amazing natural beauty, so designated as nature conservation area in the world's first-named Yellowstone National Park. Yellowstone National Park is a national park in the United States Located in the state of Wyoming, Montana, and Idaho. Covering 3468 square miles (8983 km ²).Yellowstone National Park is the world's oldest national park, established on March 1,1872 when the leadership of U.S. President Ulysses S. Grant. 
Yellowstone National Park is famous for its geysers and hot springs. World famousgeyser, Old Faithful Geyser, is here. Here also live grizzly bears, wolves, bison anddeer. Many tourists visit this place to witness the lives of wildlife and natural beauty. 
The Yellowstone Plateau volcanic field developed through three volcanic cycles spanning two million years that included some of the world's largest known eruptions. Eruption of the >2450 cu km Huckleberry Ridge Tuff about 2.1 million years ago created the more than 75-km-long Island Park caldera. The second cycle concluded with the eruption of the Mesa Falls Tuff around 1.3 million years ago, forming the 16-km-wide Henrys Fork caldera at the western end of the first caldera. Activity subsequently shifted to the present Yellowstone Plateau and culminated 640,000 years ago with the eruption of the >1000 cu km Lava Creek Tuff and the formation of the present 45 x 85 km caldera. Resurgent doming subsequently occurred at both the NE and SW sides of the caldera and voluminous (1000 cu km) intracaldera rhyolitic lava flows were erupted between 150,000 and 70,000 years ago. No magmatic eruptions have occurred since the late Pleistocene, but large phreatic eruptions took place near Yellowstone Lake during the Holocene. Yellowstone is presently the site of one of the world's largest hydrothermal systems including Earth's largest concentration of geysers.

Yellowstone's world-famous natural history is marked by such colossal volcanic events that their reflections in today's landscape are difficult to grasp and impossible to take in at just a glance, even for those familiar with the signs of past volcanism. The stunning features of Yellowstone National Park result from great explosive eruptions and profound collapse of the ground, enormously thick lava flows, uplift and extensive faulting, and the erosive power of flowing water and ice. For more than a century, geologists have discovered and analyzed evidence of the dramatic events that have shaped the land here. When combined with growing knowledge about how volcanoes work and the never-ending motion of Earth's surface, the evidence tells a remarkable story of the Yellowstone landscape.

When combined with growing knowledge about how volcanoes work and the never-ending motion of Earth's surface, the evidence tells a remarkable story of the Yellowstone landscape. 

The volcanism most directly identified with the Yellowstone region has, during about the past 2 million years, built an immense volcanic plateau that straddles a high mountain divide—the Yellowstone Plateau volcanic field. This volcanic region has evolved through 3 cycles of voluminous outpourings of rhyolite lava and volcanic ash, each of them climaxing with one of Earth's greatest pyroclastic-floweruptions and the resulting collapse of a central area to form a large caldera. Other eruptions have poured out basalt lava flows around the margins of the volcanic field. 

Yellowstone's volcanism is only the most recent in a 17 million-year history of volcanic activity that has occurred progressively from southwestern Idaho to Yellowstone National Park. At least six other large volcanic centers along this path generated caldera-forming eruptions; the calderas are no longer visible because they are buried beneath younger basaltic lava flows and sediments that blanket the Snake River Plain.  
In the 1970s, a resurvey of benchmarks discovered the unprecedented uplift of the Yellowstone Caldera of more than 28 inches (72 cm) over five decades. More recently, new and revolutionary satellite-based methods for tracking the Earth's shifting ground motions have enabled University of Utah, US Geological Survey, and other scientists to assemble a more precise and detailed picture of Yellowstone's ground movements.

The Acropolis

Acropolis is Heritage Historic in Greece, This site, shaped building natural stronghold or citadel in ancient Greece. The Greeks built their towns in plains near or around a rocky hill that could easily be fortified and defended. The word acropolis referred both to the hill and to what was built on it. Almost every Greek city had its acropolis, which provided a place of refuge for townspeople during times of war. Sometimes the ruler of the town lived within the walls of this stronghold. In many cases the acropolis became the site of temples and public buildings and thus served as the town’s religious center and the focal point of its public life and as a place of refuge.
The best-known acropolis of the ancient world is the Acropolis of Athens. The ruins of its temples and their sculptures are widely regarded as the finest examples of ancient Greek art and architecture. Built on a limestone hill that rises about 150 m (about 500 ft) above sea level, the Acropolis dominates the city of Athens. It houses the remains of the Parthenon, a magnificent temple dedicated to the goddess Athena; the Propylaea, a monumental marble gateway and the main entrance to the Acropolis; the Erechtheum, a temple famous for the perfection of its details; and the Temple of Athena Nike.

I. HISTORY OF THE ATHENIAN ACROPOLIS

The fate of the buildings on the Acropolis reflects the history of Athens. As Christianity spread through the ancient world, some of the buildings on the Acropolis were converted to churches. The Parthenon, for example, became a church in ad 426 and was rededicated to the Virgin Mary and named Our Lady of Athens in 622. After Athens came under control of the Ottoman Empire in 1458, the Parthenon became a mosque, and the Acropolis later became a garrison. In 1687 Venetian general Francesco Morosini besieged and bombarded the Acropolis, causing great damage when a cannonball ignited gunpowder stored in the Parthenon.

In the early 1800s the British ambassador to the Ottoman sultan, Lord Elgin, obtained permission to “take away pieces of stones with inscriptions or figures.” He thereafter removed most of the decoration from the Parthenon, transported the pieces to Britain, and later sold them to the British Museum, where they are on display as the Elgin Marbles. Successive Greek governments have unsuccessfully sought the return of the Parthenon sculptures.

The Acropolis was gradually restored after Greece gained its independence from Ottoman rule in 1829. Early restoration efforts concentrated on removing all additions constructed after the classical period ended in 323 bc. In the 20th century air pollution and the thousands of annual visitors to the Acropolis also caused serious damage, and measures taken from the 1970s on have focused on protecting and preserving the buildings on the Acropolis. The Erechtheum’s caryatids, for example, were removed and replaced with marble casts of the originals. Visitors can view the original caryatids in the Acropolis Museum and the British Museum. A major reconstruction project began on the Acropolis in 1981 after the buildings suffered earthquake damage. Work on the Propylaea was completed by the 2004 Summer Olympic Games held in Athens, but the Parthenon remained partially hidden by scaffolding.

II. BUILDINGS ON THE ATHENIAN ACROPOLIS
The Athenian Acropolis has been occupied since Neolithic times, but archaeologists have found few remains of its early inhabitants. During the late Bronze Age (1450 to 1200 bc), a heavily fortified palace citadel was built on the hill, and a massive stone wall was built around it. Scholars know little about the Acropolis of Athens in the period from the late Bronze Age to the Archaic period (750 to 480 bc) because later building activities obscured the traces. The Acropolis probably remained a fortified citadel while also becoming a religious sanctuary. The first stone temple to Athena, the patron goddess and protector of the city, was built on the Acropolis at the beginning of the 6th century bc. It may have stood roughly where the Parthenon now stands. Simpler temples probably preceded it.

A Greek victory in the Battle of Marathon (490 bc) near Athens inspired the Athenians to undertake an ambitious program to build new temples in celebration of their defeat of the Persians (see Persian Wars). Construction of the first temple was underway when the Persians sacked Athens in 480 bc, plundering and burning the temples and monuments on the Acropolis. The Greeks finally defeated the Persians in 479 bc, but no building took place on the Acropolis for nearly 30 years. An enormous project to rebuild the Acropolis began about 450 bc under Pericles, the leading figure in Athenian politics of the 5th century bc. The masterpieces that resulted reflect Athens at the height of its power in the ancient world.

The Propylaea

The principal entrance to the Acropolis is a monumental gateway called the Propylaea, which is made of white marble. It is located at the western end of a walled enclosure near the top of the Acropolis, at the head of a steep, winding path. It was begun in 437 bc, but work on it stopped five years later, probably because of a threat of war. The Peloponnesian War, between Athens and an alliance led by Sparta, finally broke out in 431 bc. Sparta’s alliance defeated Athens, and the Propylaea was never completed.

The Propylaea was designed by Greek architect Mnesicles to have a central section with wide openings and two wings, one to the north and the other to the south. The facade of the central section consists of six widely spaced columns in the simple Doric order (style). Inside, two rows of columns in the more elegant Ionic order divide the central area into three sections through which visitors proceed. The north wing was to house a gallery of paintings, and the south wing was to provide a passageway to the Temple of Athena Nike. The wings were never completed.

Temple of Athena Nike

The small marble Temple of Athena Nike stands just outside the Propylaea, on a projecting ridge to the south and west. This temple is the first building visitors see as they make their way up the Acropolis. It was designed by the architect Callicrates, who also worked on the Parthenon, and was built in the 420s bc in the Ionic style. Four Ionic columns stand in a row at the front and the back of this temple, which measures only 8.2 by 5.4 m (27 by 18 ft). A carved frieze (continuous horizontal band) runs around the temple just below the roof. On the east side it depicts a conference of the gods and on the other sides battle scenes from Greek mythology. The goddess Athena was the patron and protector of the city of Athens; nike (pronounced nee-kay) is Greek for “victory.” The temple is thus dedicated to Athena as the bringer of victory.

The Parthenon


The Parthenon comes immediately into view after the visitor enters the Acropolis through the Propylaea. Also dedicated to Athena, this large temple built entirely of marble is considered the greatest masterpiece of Greek architecture for its harmonious proportions, its architectural refinements, and the elegant sculptures that decorated it. The temple was designed by Greek architects Ictinus and Callicrates and was constructed from 447 to 438 bc. It measures 31 by 70 m (102 by 230 ft).

The Parthenon was built in the simple and powerful Doric order, with 8 columns along each end and 17 columns along each side. Through careful adjustments to the design and location of the Parthenon’s columns and floor platform, the architects counteracted optical illusions that could have distorted the building’s appearance from a distance. Without such adjustments, the platform might seem to sag in the middle, for example, and the columns might appear to have a slight curve in profile. A central structure with two chambers once housed a statue of Athena made of ivory and gold that was perhaps 10 m (33 ft) tall.

Phidias, considered by many to have been the finest Greek sculptor, supervised the design and execution of the sculpture on the Parthenon, which was completed in 432 bc. Sculpture adorned the pediments (triangular elements) below the roof at each end, the metopes (square panels) beneath the pediments and on all four sides of the Parthenon, and the frieze around the interior chamber. Sculpture in the west pediment depicted Athena’s contest with the god Poseidon for rule over Athens; sculptures showing Athena’s birth, flanked by gods and goddesses, decorated the east pediment. Sculptures carved on the metopes depicted legendary battles fought by the Greeks. A procession in honor of Athena ran along the frieze. Little of the original Parthenon sculpture remains in place. Many of the surviving sculptures can be seen at the British Museum in London, England. An Acropolis Museum in Athens also houses sculpture and objects from the site.

The Erechtheum

Beyond the Parthenon and near the north wall of the Acropolis stands the Erechtheum, which takes its name from Erechtheus, a hero and, according to some mythological genealogies, a king of Athens. This temple was dedicated to several deities, including Athena and Poseidon, and housed the Athenians’ most sacred statue, a wooden image of Athena Polias (Athena, goddess of the city). The Erechtheum, like the Propylaea, was probably designed by Mnesicles. Construction of it began in the 430s or 420s bc and ended in 405 bc.

The Erechtheum is one of the most elaborate buildings on the Acropolis. Its plan is irregular, probably because of the sloping site and the need to preserve earlier places of worship on the site or nearby. Porches project from three sides of the Erechtheum, but they are at different heights and are not centered on each side. Graceful Ionic columns support the porches on the eastern and northern sides. Elegant caryatids (columns carved in the shape of draped female figures) support the Porch of the Maidens on the south side.

Inca civilization

Inca civilization is vast kingdom in the Andes Mountains of South America that was created by the Quechua, a Native American people, in the 15th century ad. The Inca Empire was conquered by the Spanish in the early 16th century. The Incas built a wealthy and complex civilization that ruled between 5 million and 11 million people. The Inca system of government was among the most complex political organizations of any Native American people. Although the Incas lacked both a written language and the concept of the wheel, they accomplished feats of engineering that were unequaled elsewhere in the Americas. They built large stone structures without mortar and constructed suspension bridges and roads that crossed the steep mountain valleys of the Andes.
The Incas conquered a number of neighboring peoples as they expanded their area of influence outward from their home in the Cuzco valley of highland Peru. Inca lands eventually totaled about 906,500 sq km (about 350,000 sq mi). This territory centered on the peaks of the Andes, but extended to the Pacific Coast and the Amazon basin. The political center of the empire was in what is now Peru, and its territory included parts of present-day Ecuador, Bolivia, northern Chile, and northwest Argentina. The terrain included high grass plateaus, low-lying jungles, deserts, and fertile river valley.
   
Most of the major ideas and institutions incorporated within Inca culture developed from a series of earlier Native American civilizations in the Andes. According to legend, the people later known as Incas began as a small group of warlike people and lived near Lake Titicaca in southeastern Peru sometime before the 13th century. According to Inca myths, the first Inca emperor, Manco Capac, and his three brothers and four sisters emerged from caves in the earth. Around the year 1200, Manco Capac led ten Inca ayllus, or clans, from Lake Titicaca north to the fertile valley of Cuzco. The Incas conquered the people of the area and took it over for themselves. They founded the city of Cuzco as their capital. Manco Capac married one of his sisters, Mama Ocllo, to establish the royal Inca bloodline. He and succeeding emperors increased their power through marriage alliances and the conquest of neighboring groups. By the reign of Viracocha Inca, the eighth emperor, the Incas dominated an area stretching about 40 km (about 25 mi) around Cuzco. Recent archaeological evidence, however, shows that Inca culture was developing in the Cuzco Valley for centruries.

The Incas dramatically expanded and unified their territory after the conquest of the Chancas, under Viracocha's son, Pachacuti Inca Yupanqui. Pachacuti (whose name means 'earthquake' or 'cataclysm') reorganized the Inca social and political system. He and his son, Topa Inca Yupanqui, were brilliant soldiers and statesmen who extended the empire from northern Ecuador to central Chile. Under their leadership, the Incas united the diverse native peoples along 4800 km (3000 mi) of coast into a far-flung empire with a common Quechuan language and way of life. These leaders brought Inca civilization to its peak: They made the capital city of Cuzco into the center of Inca society and government, developed a state religion, and set up an elaborate administrative system to control their widely scattered subjects and territories.

Heritage History of the Inca Empire

Cuzco itself was a marvel of Inca building and metalwork. The great Temple of the Sun was almost entirely sheathed with gold plate. In its courtyard, figures fashioned of gold depicted scenes from Inca life. Gold corn appeared to grow out of clods of earth made of gold, and golden llamas grazed on gold grass. Other cities included Machu Picchu, whose ruins were discovered in 1911.

Machu Picchu is a heritage of historic Inca empire. Machu Picchu can be defined "lost city", the form of temples building complex , fortresses, temples, palaces and residential areas. The most impressive of the Incas’ building projects were their vast temples, palaces, and fortresses. Massive stone buildings, such as the fortress at Sacsahuaman near Cuzco, were skillfully erected with a minimum of engineering equipment. The wall of Sacsahuaman was made of enormous stones, the largest of which weighed 200 tons. Stones were transported with the help of wooden rollers, and they fitted together so exactly that no mortar was necessary.
Machu Picchu, located in the Andes Mountains, about 80 km (about 50 mi) northwest of Cuzco, Peru. Located at a high altitude on a ridge between two peaks, about 600 m (about 1950 ft) above the Urubamba River, the ruined city covers about 13 sq km (about 5 sq mi) of terraces built around a central plaza and linked by numerous stairways. The majority of buildings are one-room stone houses (now roofless), arranged around internal courts; some larger structures were evidently used for religious purposes. All are distinguished by engineering skill and fine craftsmanship. The city was discovered in 1911 by the American explorer Hiram Bingham; it is not mentioned in the writings of the Spanish conquerors of Peru, and the time of its occupancy is uncertain. Bingham believed that Machu Picchu might have been the last refuge of Incas from Cuzco fleeing the Spanish invaders, but nothing is actually known of its history.

Garden of Babylon

Hanging Gardens Babylon is one heritage history ancient civilization babylonian. This site is one Seven Wonders Ancient World, located in Al-Hillah, 50 KM south of Baghdad, Iraq, and east of the River Euphrates. The term hanging garden does not mean hanging using a rope, only just its location on the mainland is a bit high. this garden area estimated 4 acres (1 acre = 4046.86 m). Its architecture is unique, because it is stratified. The park is planted with a variety of beautiful trees and equipped with irrigation systems to a height of 100 meters above ground level. From the top of this garden scene can view around the kingdom of Babylon. 

Like the Taj Mahal in Agra India, the hanging garden is also a form from the power of love. A very deep sense of love to his wife inspired the king Nebuchadnezzar II, give a gift a beautiful hanging garden. Hanging garden made ​​around the year 600 BC as a gift to his wife, Amyitis. Amytismiss the trees and fragrant plants such as in Persia. This park estimated destroyedaround 2 century BC. Then this hanging Parks documented by Greece historians such as Strabo and Diodorus Circulus. 

The Hanging Gardens of Babylon, built by King Nebuchadnezzar II about 600 BC, were a mountainlike series of planted terraces. Ancient historians report that Babylon at that time was dazzling in the splendor of its palace and temple buildings, fortification walls, and paved processional ways. The Hanging Gardens consisted of several tiers of platform terraces built upon arches and extending to a great height. Accounts of their height range from about 24 m (80 ft) to a less reliable estimate of more than 90 m (300 ft). Trees and colorful plants and flowers grew on the terraces, irrigated with water brought up from the Euphrates River. Archaeologists have discovered remains of walls along the Euphrates that may have belonged to the Hanging Gardens.

Nebuchadnezzar's conquests brought in much booty and tribute, creating an age of prosperity for Babylonia. He undertook an ambitious construction program, rebuilding the temples in the major cult cities and refurbishing his capital at Babylon with a splendid ziggurat (pyramid temple) as well as other shrines, palaces, fortification walls, and processional ways. Later legend credited him with building one of the Seven Wonders of the World, the Hanging Gardens of Babylon, for his Median wife Amyitis. Nebuchadnezzar died in early October 562 bc and was succeeded by his son Amel-Marduk (the biblical Evil-Merodach) (626-539 bc).

The Babylonians, in coalition with the Medes and Scythians, defeated the Assyrians in 612 bc and sacked Nimrud and Nineveh. They did not establish a new style or iconography. Boundary stones depict old presentation scenes or the images of kings with symbols of the gods. Neo-Babylonian creativity manifested itself architecturally at Babylon, the capital. This huge city, destroyed (689 bc) by the Assyrian Sennacherib, was restored by Nabopolassar and his son Nebuchadnezzar II. Divided by the Euphrates, it took 88 years to build and was surrounded by outer and inner walls. Its central feature was Esagila, the temple of Marduk, with its associated seven-story ziggurat Etemenanki, popularly known later as the Tower of Babel. The ziggurat reached 91 m (300 ft) in height and had at the uppermost stage a temple (a shrine) built of sun-dried bricks and faced with baked bricks.

From the temple of Marduk northward passed the processional way, its wall decorated with enamelled lions. Passing through the Ishtar Gate, it led to a small temple outside the city, where ceremonies for the New Year Festival were held. West of the Ishtar Gate were two palace complexes; east of the processional way lay, since the times of Hammurabi, a residential area. Like its famous Hanging Gardens, one of the Seven Wonders of the World, at the palace of Nebuchadnezzar II, little of the city remains. The Ishtar Gate (575? bc) is one of the few surviving structures. The glazed-brick facade of the gate and the processional way that led up to it were excavated by German archaeologists and taken to Berlin, where the monument was reconstructed. The large complex, some 30 m (about 100 ft) long, is on display in the city's Vorderasiatische Museum. On the site of ancient Babylon, restoration of an earlier version of the Ishtar Gate, the processional way, and the palace complex, all constructed of unglazed brick, has been undertaken by the Iraq Department of Antiquities.

ancient mayans,world heritage sites

Ancient maya civilization is one the world heritage sites. Maya Civilization, an ancient Native American culture that represented one of the most advanced civilizations in the western hemisphere before the arrival of Europeans. The people known as the Maya lived in the region that is now eastern and southern Mexico, Guatemala, Belize, El Salvador, and western Honduras. They thrived for more than 2,000 years. The Maya built massive stone pyramids, temples, and sculpture; developed a system of writing using hieroglyphs; and recorded their achievements in mathematics and astronomy. Archaeologists long believed that Maya culture reached its highest development from about ad 300 to 900, during what is known as the Classic period. Recent discoveries in northern Guatemala, however, have challenged that assumption. There, archaeologists have found highly developed cities, sophisticated art, and examples of Maya writing that date from as early as 600 years before the Classic period began.

After 900 the Maya mysteriously declined in the southern lowlands of Guatemala. They later revived in the north on the Yucatán Peninsula and continued to dominate the area until the Spanish conquest in the 16th century. Descendants of the Maya still form a large part of the population of the region. Although many have adopted Spanish ways, a significant number of modern Maya maintain traditional cultural practices.

PRE CLASSIC PERIOD

Many aspects of Maya civilization developed slowly through a long Preclassic period, from about 2000 bc to ad 300. By the beginning of that period, Mayan-speaking Native Americans were settled in three adjacent regions of eastern and southern Mexico and Central America: the dry, limestone country along the north coast of Mexico’s Yucatán Peninsula; the inland tropical jungle in the Petén region of northern Guatemala; and an area of volcanic highlands and mountain peaks in southern Guatemala near the Pacific Ocean.


The earliest Maya were farmers who lived in small, scattered villages of pole and thatch houses. They cultivated their fields as a community, planting seeds in holes made with a pointed wood stick. Later in the Preclassic period, they adopted intensive farming techniques such as continuous cultivation involving crop rotation and fertilizers, household gardens, and terraces. In some areas, they built raised fields in seasonal swamps. Their main crops included maize (corn), beans, squash, avocados, chili peppers, pineapples, papayas, and cacao, which was made into a chocolate drink with water and hot chilies. The women ground corn on specially shaped grinding stones and mixed the ground meal with water to make a drink known as atole or to cook as tortillas (flat cakes) on flat pottery griddles. The Maya also drank balche made from fermented honey mixed with the bark of the balche tree. Rabbits, deer, and turkeys were hunted for making stews. Fishing also supplied part of their diet. Turkeys, ducks, and dogs were kept as domesticated animals.

When they were not hunting, fishing, or in the fields, Maya men made stone tools, clay figurines, jade carvings, ropes, baskets, and mats. The women made painted pottery vessels out of coiled strands of clay, and they wove ponchos, men’s loincloths, and women’s skirts, out of fibers made from cotton or from the leaves of the maguey plant. They also used the bark of the wild fig tree to make paper, which they used primarily for ceremonial purposes. Since the Maya had neither draft animals nor wheeled vehicles, they carried goods for trade over the narrow trails with tumplines (backpacks supported by a strap slung across the forehead or chest) or transported them in dugout canoes along the coasts and rivers.


The early Maya probably organized themselves into kin-based settlements headed by chiefs. The chiefs were hereditary rulers who commanded a following through their political skills and their ability to communicate with supernatural powers. Along with their families, they composed an elite segment of society, enjoying the privileges of high social rank. However, these elites did not yet constitute a social class of nobles as they would in the Classic period. A council of chiefs or elders governed a group of several settlements located near one another. The council combined both political and religious functions.

Like other ancient farming peoples, the early Maya worshiped agricultural gods, such as the rain god and, later, the corn god. Eventually they developed the belief that gods controlled events in each day, month, and year, and that they had to make offerings to win the gods’ favor. Maya astronomers observed the movements of the sun, moon, and planets, made astronomical calculations, and devised almanacs (calendars combined with astronomical observations). The astronomers’ observations were used to divine auspicious moments for many different kinds of activity, from farming to warfare.

The Maya did not remain an entirely agricultural people living in villages during the pre-Classic period. Rulers and nobles directed the commoners in building major settlements, such as Kaminaljuyú, in the southern highlands, and Tikal, in the central lowlands of the Petén jungle. Pyramid-shaped mounds of rubble topped with altars or thatched temples sat in the center of these settlements, and priests performed sacrifices to the gods on them. As the Preclassic period progressed, the Maya increasingly used stone in building. Both nobles and commoners lived in extended family compounds.

During the Preclassic period the basic patterns of ancient Maya life were established. However, the period was not simply a rehearsal for the Classic period but a time of spectacular achievements. For example, enormous pyramids were constructed at the site of El Mirador, in the lowlands of Guatemala. These pyramids are among the largest constructions in the ancient Maya world. By about 500 bc El Mirador was a major population center that served as the seat of a powerful chiefdom. Pyramids also were built on large plazas at Cival, a royal metropolis near Tikal in Guatemala. Cival probably had 10,000 inhabitants.


The highland and the lowland regions were in close contact at this time. Obsidian, a smooth volcanic rock used to make weapons and tools, from highland Guatemala has been found at El Mirador, and a sculptural style that originated in the Pacific lowland region of Chiapas and Guatemala was common in the southern highlands. Kaminaljuyú was the most powerful chiefdom of the highlands, and it probably controlled the flow of obsidian to the lowlands. Control of this important resource allowed Kaminaljuyú to dominate trade networks. Economic and political institutions during this period were more advanced in the southern highland area.

CLASSIC PERIOD

Classic Maya kings carried the title k’ul ahau (supreme and sacred ruler). In the latter part of the Classic period, kings were assisted in governing by a hereditary ruling council. The power of the king existed as both a political and religious authority in this period. In contrast, the king’s religious power declined during the Postclassic period (ad 900 to 1521) because the institution of priesthood appeared.


Merchants were important to Maya society because of the significance of trade. Principal interior trade routes connected all the great Classic lowland centers and controlled the flow of goods such as salt, obsidian, jade, cacao, animal pelts, tropical bird feathers, and luxury ceramics. In the early Classic period Teotihuacán in central Mexico emerged as the greatest city in Mesoamerica, an area that included modern Mexico and most of Central America. The religious and political power of Teotihuacán radiated throughout Mesoamerica. One result of Teotihuacán’s influence was a highly integrated network of trade in which the Maya participated.

Highland Maya from the southern region carried obsidian for tools and weapons; grinding stones; jade; green parrot and quetzal feathers; a tree resin called copal to burn as incense; and cochineal, a red dye made from dried insects. Those from the lowlands brought jaguar pelts, chert (flint), salt, cotton fibers and cloth, balche, wax, honey, dried fish, and smoked venison. People either bartered goods directly or exchanged them for cacao beans, which were used as a kind of currency. Wealth acquired from trade enabled the upper classes to live in luxury, although there was little improvement in the lives of the lower classes.


A Maya nobleman wore an embroidered cotton loincloth trimmed with feathers; a robe of cotton, jaguar skin, or feathers; sandals; and an elaborate feather headdress that was sometimes as large as himself. His head had been fashionably elongated by being pressed between boards when he was a few days old, and his eyes had purposely been crossed in childhood by having objects dangled before them. His nose was built up with putty to give it an admired beak shape, and his ears and teeth were inlaid with jade. A noblewoman wore a loose white cotton robe that was often embroidered. Her head was also elongated, and she filed her teeth to points.

Nobles lived in houses of cut stone with plastered walls that often bore brightly painted murals. In the living room nobles gave banquets of turkey, deer, duck, chocolate, and balche. The guests were expected to bring gifts and to give a banquet in return. A dead noble was buried in a stone vault with jade and pottery ornaments, and occasionally with human sacrifices, which were provided to serve him in the afterlife.

Most of the Maya people were village farmers who gave two-thirds of their produce and much of their labor to the upper classes. Commoner men wore plain cotton loincloths and simple tunics. Women wore woven cotton blouses and skirts or loose-fitting sack dresses with simple embroidered patterns. Women and girls wore their hair long and took care that it was always combed and arranged attractively. Different hairstyles signaled the marital status of women. Both men and women tattooed their bodies with elaborate designs.

At the bottom of Maya society were slaves who were convicted criminals, poor commoners who sold themselves into bondage, captives of war, or individuals acquired by trade. Slaves performed menial tasks for their owners and they were often sacrificed when their owners died so that they could continue to serve in the afterlife.

Although Maya builders possessed many practical skills, the most distinctive Maya achievements were in abstract mathematics and astronomy. One of their greatest intellectual achievements was a pair of interlocking calendars, which was used for such purposes as the scheduling of ceremonies. One calendar was based on the sun and contained 365 days. The second was a sacred 260-day almanac used for finding lucky and unlucky days. The designation of any day included the day name and number from both the solar calendar and the sacred almanac. The two calendars can be thought of as two geared wheels that meshed together at one point along the rim, with the glyphs for the days of the sun calendar on one wheel and the glyphs for the days of the sacred almanac on the other. With each new day the wheels were turned by one gear. The name for each day was formed by combining the name for the sun calendar day with the name for the sacred almanac day.

Maya astronomers could make difficult calculations, such as finding the day of the week of a particular calendar date many thousands of years in the past or in the future. They also used the concept of zero, an extremely advanced mathematical concept. Although they had neither decimals nor fractions, they made accurate astronomical measurements by dropping or adding days to their calendar. For example, during 1000 years of observing the revolution of the planet Venus, which is completed in 583.92 days, Maya astronomers calculated the time of the Venusian year as 584 days. The Maya method of reckoning time involved counting forward from a hypothetical fixed point and expressing the date in time periods based on the number 20 and counted in intervals of 1, 20, 360, 7200, and 144,000 days. Such dates appear on carved stone monuments dating to as early as the late Preclassic period, and they are prevalent throughout the lowlands on monuments from the Classic period.


The Maya developed a complex system of hieroglyphic writing to record not only astronomical observations and calendrical calculations, but also historical and genealogical information. Many recent advances have occurred in the decipherment of the Mayan script. These breakthroughs made it possible to conclude that Mayan hieroglyphs were a mixture of glyphs that represent complete words and glyphs that represent sounds, which were combined to form complete words. Scribes carved hieroglyphs on stone stelae, altars, wooden lintels, and roof beams, or painted them on ceramic vessels and in books made of bark paper. Discoveries reported early in 2006 indicate that the Maya were writing more than 2,300 years ago, at least 600 years earlier than previously thought.

From about ad 790 to 889, Classic Maya civilization in the lowlands collapsed. Construction of temples and palaces ceased, and monuments were no longer erected. The Maya abandoned the great lowland cities, and population levels declined drastically, especially in the southern and central lowlands. Scholars debate the causes of the collapse, but they are in general agreement that it was a gradual process of disintegration rather than a sudden dramatic event. A number of factors were almost certainly involved, and the precise causes were different for each city-state in each region of the lowlands. Among the factors that have been suggested are natural disasters, disease, soil exhaustion and other agricultural problems, peasant revolts, internal warfare, and foreign invasions. Whatever factors led to the collapse, their net result was a weakening of lowland Maya social, economic, and political systems to the point where they could no longer support large populations. Another result was the loss of inestimable amounts of knowledge relating to Maya religion and ritual.

Pembelajaran IPS Terpadu

Pembelajaran terpadu pada mata pelajaran IPS sangat diperlukan dalam pelaksanaan KTSP, mengingat standar isi mata pelajaran IPS pada dasarnya sudah menganut prinsip integrasi. Namun kenyataan di lapangan guru masih kesulitan menerapkan pola integrasi baik inter disipliner maupun intra disipliner. Mainset guru masih terkotak-kotak sesuai pada bidang ilmunya ketika menempuh pendidikan S1. Hal ini adalah implikasi karena LPTK masih jarang bahkan mungkin belum ada yang meluluskan guru-guru IPS.
Yang ada adalah guru geografi, guru sejarah, guru ekonomi, dan sosiologi. Bagaimana menerapkan pola pembelajaran IPS terpadu dalam KBM? Bagaimana perencanaannya mulai dari pemetaan KD hingga pelaksanaan Di kelas? apa saja kendala-kendala penerapan pembelajaran IPS terpadu? untuk menjawab pertanyaan-pertanyaan barusan, saya coba sediakan panduan dengan harapan dapat memberikan solusi atau setidak-tidaknya bahan diskusi terutama bagi guru-guru IPS SMP/MTs.
