Egyptian pyramids found by infra-red satellite images

Seventeen lost pyramids are among the buildings identified in a new satellite survey of Egypt.
More than 1,000 tombs and 3,000 ancient settlements were also revealed by looking at infra-red images which show up underground buildings.

Initial excavations have already confirmed some of the findings, including two suspected pyramids.
The work has been pioneered at the University of Alabama at Birmingham by US Egyptologist Dr Sarah Parcak.

She says she was amazed at how much she and her team has found.

"We were very intensely doing this research for over a year. I could see the data as it was emerging, but for me the "Aha!" moment was when I could step back and look at everything that we'd found and I couldn't believe we could locate so many sites all over Egypt.

"To excavate a pyramid is the dream of every archaeologist," she said.

The team analysed images from satellites orbiting 700km above the earth, equipped with cameras so powerful they can pin-point objects less than 1m in diameter on the earth's surface.

Infra-red imaging was used to highlight different materials under the surface.

Test excavations
Ancient Egyptians built their houses and structures out of mud brick, which is much denser than the soil that surrounds it, so the shapes of houses, temples and tombs can be seen.

"It just shows us how easy it is to underestimate both the size and scale of past human settlements," says Dr Parcak.

And she believes there are more antiquities to be discovered:
"These are just the sites [close to] the surface. There are many thousands of additional sites that the Nile has covered over with silt. This is just the beginning of this kind of work."

BBC cameras followed Dr Parcak on her "nervous" journey when she travelled to Egypt to see if excavations could back up what her technology could see under the surface.

In the BBC documentary Egypt's Lost Cities, they visit an area of Saqqara (Sakkara) where the authorities were not initially interested in her findings.

But after being told by Dr Parcak that she had seen two potential pyramids, they made test excavations, and they now believe it is one of the most important archaeological sites in Egypt.

But Dr Parcak said the most exciting moment was visiting the excavations at Tanis.

"They'd excavated a 3,000-year-old house that the satellite imagery had shown and the outline of the structure matched the satellite imagery almost perfectly. That was real validation of the technology."

The Egyptian authorities plan to use the technology to help - among other things - protect the country's antiquities in the future.

During the recent revolution, looters accessed some well-known archaeological sites.

"We can tell from the imagery a tomb was looted from a particular period of time and we can alert Interpol to watch out for antiquities from that time that may be offered for sale."

She also hopes the new technology will help engage young people in science and will be a major help for archaeologists around the world.

"It allows us to be more focused and selective in the work we do. Faced with a massive site, you don't know where to start.

"It's an important tool to focus where we're excavating. It gives us a much bigger perspective on archaeological sites. We have to think bigger and that's what the satellites allow us to do."

"Indiana Jones is old school, we've moved on from Indy. Sorry, Harrison Ford."

Egypt's Lost Cities is on BBC One on Monday 30 May at 2030 BST.

The Ten Suns of Heaven

In the beginning, there were ten suns, the sons of Di Jun, Chinese Emperor of the Eastern Heavens, and his wife Xi He, goddess of the sun. They lived in a giant mulberry tree that grew up from the waters of the Heaven Valley—waters that were always boiling hot because the suns all bathed there. Each morning, the suns took turns shining in the sky, leaving the others resting in the tree. But one day, bored with their orderly life, they all rushed up into the sky at once and ran around wildly having fun. Their tenfold strength began to scorch the earth but when their parents told them to behave and come down they would not listen. So Di Jun sent his archer, Hou Yi, to teach his sons a lesson. Yi then shot down nine of the ten suns. Di Jun was devastated and he stripped Yi and his wife Chang E of their immortality and banished them from heaven.

Pan Gu Creates the World
In the beginning, the universe was contained within an egg, inside of which the vital forces of yin (dark, female, and cool) and yang (light, male, and hot) interacted with each other. Inside the egg, Pan Gu, formed from these forces, slept for 18,000 years. When he awoke, he stretched and broke the egg. The heavier elements inside the egg sank to form the earth, and the lighter ones floated to form the sky. Between the earth and the sky was Pan Gu. Every day, for another 18,000 years, the earth and sky separated a little more, and every day Pan Gu grew at the same rate so that he always filled the space in between. At last the earth and sky reached their final positions, and exhausted, Pan Gu lay down to rest. But he was so worn out that he died. His torso and limbs became the mountains. His eyes became the sun and moon, his flesh the land, his hair the trees and plants, and his tears the rivers and seas. His breath became the wind, and his voice the thunder and lightning. Finally, Pan Gu’s fleas became humankind.

Creation myths of Nü Wa
Human beings were created by the goddess Nü Wa, either out of mud and water, or with her brother Fu Xi. Wanting the gods’ approval, she and Fu Xi lit two bonfires and said, “If Heaven wants us to marry, may the smoke of the two fires mingle; if not, may it drift in separate ways.” It mingled, so they married; but Nü Wa was shy and covered her face with a fan—as brides still do today. Nü Wa felt protective toward humanity. When Gong Gong, the Water God, made holes in the sky during a battle with Zhu Rong, the Fire God, and the whole world was unbalanced and ravaged by fire and flood, Nü Wa melted stones to plug the gap and make the sky as good as new. And, to make it extra safe, she killed a giant turtle and used its four legs as pillars to support the four corners of heaven.

Lalibela

The 11 12th-century churches chiselled out of red volcanic rock at Lalibela still hum with the sound of murmured prayer and the shuffle of bare feet.

Lalibela is a town in northern Ethiopia, known for its monolithic churches. Lalibela is one of Ethiopia's holiest cities, second only to Aksum, and is a center of pilgrimage for much of the country. Unlike Aksum, the population of Lalibela is almost completely Ethiopian Orthodox Christian. The layout and names of the major buildings in Lalibela are widely accepted, especially by the local clergy, to be a symbolic representation of Jerusalem. This has led some experts to date the current form of its famous churches to the years following the capture of Jerusalem in 1187 by the Muslim soldier Saladin.

Qutb Minar

The five-story Qutb (pole or axis) Minar (tower) in Delhi was begun in 1193 by Qutbuddin Aibak, a slave who rose to become a general, and finally the ruler of the Mamluk (Slave) dynasty (ad 1206–46). This massive stone structure was, for many years, the world’s highest single tower. The minar marked Aibak’s victory over the Rajputs, and the start of Muslim rule in India. It took stonemasons and sculptors over 150 years to build, and was finally completed in 1368.

Lalkot is the first of the seven cities of Delhi, established by the Tomar Rajput ruler, Anang Pal, in 1060. The Qutb complex lies in the middle of the eastern part of Lalkot. Building of the Quwwatu'l-Islam (Might of Islam) congregational mosque was begun in 1192 by Qutbu'd-Din Aibak and completed in 1198, using the demolished remains of Hindu temples. It was enlarged by Iltutmish (1211-36) and again by Alauld-Din Khalji (1296-1316).

The Qutb Minar was also begun by Qutbu'd-Din Aibak, in around 1202 and completed by his successor, Muhammad-bin-Sam. It was damaged by lightning in 1326 and again in 1368, and was repaired by the rulers of the day, Muhammad-bin-Tughluq (1325-51) and Firuz Shah Tughluq (1351-88). In 1503 Sikandar Lodi carried out some restoration and enlargement of the upper storeys. The iron pillar in the mosque compound was brought from elsewhere in India. It bears a Sanskrit inscription from the 4th century AD describing the exploits of a ruler named Chandra, believed to be the Gupta King Chandragupta II (375-413). Of the other monuments, the Tomb of Iltutmish was built in 1235 by the ruler himself and Alai Darwaja was built in 1311 by Alauld-Din Khalji, who also began the construction of the Alai Minar.

The Quwwatu'l-Islam mosque consists of a courtyard, cloisters, and a prayer hall. The high arched screen facing the prayer hall was added in the 14th century. The Qutb Minar is a column built from red and buff sandstone blocks rising to a height of 72.5 m, tapering from 2.75 m diameter at the top to 14.32 m at the base, making it the highest stone tower in India. In addition to its traditional use for calling the faithful to prayer, it also has a monumental purpose, since a later Nagari inscription calls it Alauld-Din's 'victory monument' (Vijava-stambha). In its present form it consists of five storeys, the topmost of the original four storeys having been replaced by two storeys during the reign of Firuz Shah Tughluq. Each storey is separated from the next by highly decorated balconies, with pendentives and inscribed bands. The three earlier storeys are each decorated differently, the lowest being of alternating angular and rounded flutings, the second with rounded flutings alone, and the third with angular flutings alone; the same vertical alignment continues, however, through all three storeys. The whole structure was originally surmounted by a cupola, which fell during an earthquake and was replaced by a new cupola in late Mughal style in the early 19th century. This was so incongruous that it was removed in 1848 and now stands on the lawns to the south-east of the minaret.

The Iron Pillar is 7.02 m long, 0.93 m of which is below ground. It is built up of many hundreds of small wrought-iron blooms welded together and is the largest known composite iron object from so early a period. The remarkable lack of corrosion is attributable to the combination of several factors, among them the high corrosion-resistance of wrought iron, the climatic conditions in Delhi, and the likelihood that it was frequently anointed with ghee (melted butter). The deep cavity at the top suggests that it may at one time have been crowned by a Garuda image. The ornate Tomb of Iltutmish is in the north-west corner of the mosque. It consists of a square chamber of red sandstone with the tomb itself in the centre on a raised platform. The lower part of the interior is covered with fine Islamic carvings and arabesques. There is a marble mihrab (prayer niche) in the centre of the interior west wall. The Alai Darwaza, built from red sandstone and elaborately carved, is the southern entrance to the enlarged enclosure of the Qutb complex. The Alai Minar, to the north of the enclosure, is the base of a second minaret which was to overtop the Qutb Minar. It was begun by Alau'd-Din-Khalji, but he died before it reached the first storey and work on the structure was abandoned.

Until the thirteenth century Muslims continued to treat India as a land fit only for periodic plunder, a domain at “war,” rather than in “submission.” However, after 1206—the dawn of the Delhi sultanate, when the first of five Muslim dynasties established dominance over North India—Muslim rule remained an integral part at least of some portion of South Asia, if not its entire length and breadth. The Afghan “Slave” (Mamluk) dynasty lasted less than a century, followed by tougher Turkish Khaljis, who brought the faith of Islam to the Deccan, looting and plundering Devagiri, capital of pastoral Yadavas, worshipers of Krishna. Under Ala-ud-din Muhammad Khalji (r. 1296–1316), the sultanate reached its peak of power, but his sons were unable to consolidate their father’s phenomenal conquests.
The Sultanate Period (1192–1526)
As Ghaznavid power declined, it gave way to the reign of other “slave kings,” which included the dynastic succession of the Ghorids (1192–1290), the Khaljis (1290–1320), and the Tughluqs (1320–1398), culminating in the Lodi (1451–1526) dynasty. The Sultanate period, which lasted from the late twelfth to the early sixteenth centuries, began with the invasion of India by Muiz al-Din Ghori, who was of Turkish origin. Unlike Mahmud of Ghazni, who came to India simply to plunder and loot, Ghori and his descendants aimed to establish political control which manifested itself as the Delhi Sultanate.

The sultanates created a relatively stable political structure during this period, while the ultimate political authority rested with the Turkic sultans who, at least nominally, displayed Islam as their religious as well as political ideology. Among the populace, the religion of Islam meant something different. It was not synonymous with power or political dominance, and mostly grew among the poor. In fact, in the multifaceted social structure that developed in the midst of this complex period, it was generally acknowledged within the Muslim populace that the ulama held a religious authority that could not be subordinated or abrogated by the sultan, be he a local or imperial sultan. Instead, sultans generally attempted to legitimize their rule by acknowledging the authority of local ulama and particularly of Sufi saints.

It should be noted that during this period there was a creative cultural melding of traditions, which resulted in systems of military cooperation strong enough to head off the powerful Mongol advance, agrarian management systems that would survive well into the British colonial period, and an artistic and architectural synthesis so compelling that its creations still draw tourists to India today. Through the medieval period, Muslim intellectuals, Sufis, artisans, and travelers in general were attracted to South Asia from all parts of the Muslim world. This resulted in an administrative system resembling Islamic structures developed in the Muslim caliphates of Iraq and Syria.

The role of the Sufis was central to the growth of Islam, as they were generous in establishing their khanqahs. These centers also served as places for devotional and therapeutic needs. Sufis and religious leaders filled the need for education as well as spiritual fulfillment.

As the Delhi Sultanate became weak at the center, it resulted in the emergence of regional dynasties—in Bengal in the east and Gujarat in the west. The Bahmani kingdom in the south became independent of the Sultanate in 1347 and lasted for almost two hundred years before being split up into four smaller kingdoms. Its rulers, patrons of Sufi saints, also supported a variety of forms of Indo-Islamic art and the spread of Islamic tradition in South India.

In this regional arrangement of political power, Muslim culture developed in collaboration with local linguistic and social norms. This contributed to the increasing diversity of Islamic societies, cultures, and traditions. Muslim rulers and nobles formed alliances based on political and economic interests that went beyond religious and sectarian (Shia-Sunni) affiliation. Hindu kings fought with Turkish rulers, Muslim rebels collaborated with Hindus to secede from the Sultanate’s center, and so on.

Wisdom of the oracle

Delphi is located on the southern slopes of sacred Mount Parnassus, about 12 miles from the Gulf of Corinth. While some come here to question the oracle, most attend the site to celebrate a festival of Apollo or Dionysus. This reconstruction shows the entire Delphi complex, from the stadium at the top to the Sanctuary of Athena at the very bottom. The area of the plan is indicated in red.
The most famous oracle in Greece is that of Apollo at Delphi. It was discovered long ago that a cleft in the side of Mount Parnassus emitted a gas that caused seizures among the goats that grazed nearby. When a goatherd was also affected, the locals interpreted his convulsions and ravings as divine inspiration.

This became the place decreed by Apollo to be the omphalus (navel) of the world. Delegations now travel from all over Greece to seek advice, the words of Apollo interpreted through the medium of the Pythia, high priestess of Delphi.

The Pythia is crowned in laurel and seated on a tripod perched over the vaporous cleft. Any man (women are not allowed in the sanctuary) wishing to ask a question about the future must first be ritually purified by washing in the Castalian Spring, which is where Apollo killed the Python dragon.

The request is written down and given to the Pythia by a priest. Her utterances are usually so disjointed that her servant-priests are needed to interpret the answer—even then, they often get it wrong, to the questioner’s usually dreadful misfortune.
#
The celebrant climbs a steep road toward the sanctuary entrance at its eastern corner. During a major festival this road is lined by numerous stores selling the pilgrims food, mementoes of their visit, and sacrificial offerings to place on the many altars. From the gate, the Sacred Way rises steeply in a zigzag, between the votive altars and then the state treasuries of several city-states.

It takes a sharp bend in front of the Athenian treasury before passing close to the rock on which in ancient times the mythical prophetess Sibyl sang her predictions in Gaia’s shrine. From here, the procession continues up past the Porch of the Athenians. This stoa (a covered walkway) is built in the Ionic order, and has seven fluted, or grooved columns, each made from a single stone. According to the inscription, it was erected by the Athenians after 478 BCE to house the trophies taken in their naval victories over the Persians.

 The Sacred Way now bends around to take the last, steep rise up to the great Doric temple dedicated to Apollo. Inside is the adyton, the seat of the Pythia.

Facing the steps to the temple’s entrance is the large altar of the sanctuary. It was paid for and erected by the people of Chios, in the 5th century BCE. The monument is made of black marble, except for the base and cornice, which are of white marble, resulting in an impressive color contrast.

Heart of the Polis—the Agora

AAthens is governed by an assembly of 500 elected members— called the Boule—who meet in the New and Old Bouleuterion. A “steering committee” of 50 selected Boule members, called the prytani, meets in the circular Tholos, which also houses the official weights and standard measures. B The old law court (top right) fell into disuse early on and cases are heard in the Hellaea, which is incorporated in the new south stoa. C The ancient race track has disappeared under the agora’s center, which is filled with market stalls and small stores.

The Greek agora, or marketplace, is a natural place for exchanging gossip, debating matters of state, and for public discussion. It is the center of trade and of politics, where the government meets and from where wars are conducted.

At the heart of every Greek city is the agora. It is the center of a city’s commercial life, and a social focus where people gather to meet friends. The finest agora in all Greece is found in Athens, which was once the place where an ancient race track existed for the annual religious games. Gradually, it developed into a market, and from there to the political hub of the city.

Farmers from the surrounding region still come to the central open space, erect their stalls, and sell meat, poultry, fish, vegetables, cheese, fruit, and eggs. Around the edges craftsmen have their numerous workshops, while here and there knots of men looking for work gather in spots where employers are known to hire for particular trades.

The political hub
To the east and south are the great stoas, or porches, colonnaded arcades that offer welcome shade and also provide space for small shops and business offices. The shops are open rooms with a counter across the front, and since they cost more to rent than a market stall, they tend to sell luxury goods.

On the western side of the agora sit the various government buildings that house the Boule and the Strategion. This is the center of the Athenian military command. In times of war, the Boule appoints a supreme commander—the strategos—who is responsible for the navy and the army. In other times, there were a number of strategoi, who acted as generals.

Together with altars and temples, you have in one place the essence of a Greek city.

Nabta

    Oldest Astronomical Megalith Alignment Discovered In Egypt. By Science Team
ScienceDaily (Apr. 3, 1998)
An assembly of huge stone slabs found in Egypt's Sahara Desert that date from about 6,500 years to 6,000 years ago has been confirmed by scientists to be the oldest known astronomical alignment of megaliths in the world.

Known as Nabta, the site consists of a stone circle, a series of flat, tomb-like stone structures and five lines of standing and toppled megaliths. Located west of the Nile River in southern Egypt, Nabta predates Stonehenge and similar prehistoric sites around the world by about 1,000 years, said University of Colorado at Boulder astronomy Professor J. McKim Malville.

The Nabta site was discovered several years ago by a team led by Southern Methodist University anthropology Professor Fred Wendorf. A 1997 GPS satellite survey by Malville, Wendorf, Ali A Mazar of the Egyptian Geological Survey and Romauld Schild of the Polish Academy of Sciences confirmed one of the megalith lines was oriented in an east-west direction.

A paper on the subject by the four researchers will appear April 2 in the weekly British science journal, Nature.

"This is the oldest documented astronomical alignment of megaliths in the world," said Malville. "A lot of effort went into the construction of a purely symbolic and ceremonial site." The stone slabs, some of which are nine feet high, were dragged to the site from a mile or more distant, he said.

The ruins lie on the shoreline of an ancient lake that began filling with water about 11,000 years ago when the African summer monsoon shifted north. It was used by nomads until about 4,800 years ago, when the monsoon moved southwest and the area again became "hyperarid and uninhabitable."

Five megalithic alignments at Nabta radiate outward from a central collection of megalithic structures. Beneath one structure was a sculptured rock resembling a cow standing upright, Malville said. The team also excavated several cattle burials at Nabta, including an articulated skeleton buried in a roofed, clay-lined chamber.

Neolithic herders that began coming to Nabta about 10,000 years ago -- probably from central Africa -- used cattle in their rituals just as the African Massai do today, he said. No human remains have yet been found at Nabta.

The 12-foot-in-diameter stone circle contains four sets of upright slabs. Two sets were aligned in a north-south direction while the second pair of slabs provides a line of sight toward the summer solstice horizon.

Because of Nabta's proximity to the Tropic of Cancer, the noon sun is at its zenith about three weeks before and three weeks after the summer solstice, preventing upright objects from casting shadows. "These vertical sighting stones in the circle correspond to the zenith sun during the summer solstice," said Malville, an archeoastronomer. "For many cultures in the tropics, the zenith sun has been a major event for millennia."

An east-west alignment also is present between one megalithic structure and two stone megaliths about a mile distant. There also are two other geometric lines involving about a dozen additional stone monuments that lead both northeast and southeast from the same megalith. "We still don't understand the significance of these lines," Malville said.

During summer and fall, the individual stone monoliths would have been partially submerged in the lake and may have been ritual markers for the onset of the rainy season. "The organization of these objects suggest a symbolic geometry that integrated death, water and the sun," Malville said.

Although some believe the "high culture" of subsequent Egyptian dynasties was borrowed from Mesopotamia and Syria, Malville and others believe the complex and symbolic Nabta culture may have stimulated the growth of the society that eventually constructed the first pyramids along the Nile about 4,500 years ago.

"The Nabta culture may have been a trigger for the development of social complexity in Egypt that later led to the Pharaonic dynasty," he said. The Nabta project was funded primarily by the National Science Foundation.

The site also contains a wealth of cultural debris, including small, fire-blackened stones from ancient hearths built along the ancient lakeshore as well as manos, metates and carved and decorated ostrich eggshells.

Mỹ Sơn

Perhaps because so many people travelling down the Vietnamese coast are en route to Angkor Wat in Cambodia, My Son, about an hour from Hoi An, often gets overlooked. Yet it’s an incredible, eerie site of towering temples, covered in jungle creepers.

Paro Taktsang

Clinging to the edge of a 900m cliff, Taktshang Goemba (Tiger’s Nest Monastery) is famous in Bhutan but like so much of the remote kingdom, little-known outside. The monastery is not open to visitors but you can hike to a viewpoint to take in the epic scenery.

The Nabta megaliths were recently discovered in the Egyptian Sahara.

Oldest Astronomical Megalith Alignment Discovered In Egypt
The Nabta megaliths were recently discovered in the Egyptian Sahara. The circle of stones is astronomically aligned, although no one is sure of its exact purpose. It dates to between 4500 and 4000 BCE – making it 1,000 years older than the circle at Stonehenge in Wiltshire, England.

The Nabtans erected five megalithic alignments all radiating like wheel spokes from a central cluster of stones.

Nabta boasts numerous fire hearths located around a stone calendar circle about 300 meters north of the mega stones. This stone circle is very small compared with the great structures of Stonehenge and Carnac but it demonstrates similar astronomical affiliations. Archaeologists, using global positioning systems, have surveyed the large radial stones and found that their alignments are exactly on the axis north-south and east-west as are the stones of the calendar circle.

The east-west line has been calculated to align with the rising and setting sun of the summer solstice more than 6,000 years ago.
Many cattle bones have been discovered, adding to the speculation that this was a place of animal veneration. The ancient Egyptians deified cattle, especially the cow. One tumulus contained a fully articulated cow while numerous other, more basic, tumuli contained some artifacts, unshaped stones, and disarticulated cattle bones.

Galilee

The vast majority of Bible narratives occur in the hills, from the Galilee in the north, down through Samaria to Jerusalem and Bethlehem. “There is some rainfall (above 24 in.). The nights are cool in summer, cold in winter, when frost and snow are unusual but not unknown” (George Cansdale 1970, 27). The forests that once covered these hills are mentioned in stories of David. His son Absalom was killed in a forest, when his long hair caught on the branches of the trees. At one time, the region was alive with wild animals, which found plenty of grazing land, as well as fruits and nuts from the variety of trees.

The rock formations in the sandstone provide many holes and clefts that have served as homes to humans and beasts throughout the centuries. This was an excellent hiding place for David when he was fleeing Saul, and it was later used to shelter the Zealots and outlaws in Jesus’s day.

Galilee, the home of Jesus and his disciples, is north of the Plain of Esdraelon. The upland ranges of the hills here “stretch away northward, gradually rising as they come nearer to the high mountains of Lebanon. They rise in a series of steps, with scarp edges, facing generally south or south-east. The lower steps in the ‘staircase’ were and are fertile basin lands, separated from each other by barren limestone edges. In the time of Jesus, these basins were known for their grain, fruit and olives. They formed a prosperous, well-populated area. But the higher steps rise to a bleak and windswept upland. This is isolated and infertile, and lacks the forests of the higher mountain slopes farther north” (Pat Alexander, Eerdman ’ s Family Encyclopedia of the Bible, 6–7). This was sometimes divided into the Lower and Upper Galilee, with the northern section often under foreign control.

Galilee was a busy region, crossed by the great trade routes, bringing many strangers with news of the outside world; a mixed community with fishermen casting their nets on the Sea of Galilee and farmers tilling the soil of their fertile farmlands. It was full of people who were more racially mixed than in the Jerusalem region, and considered hayseeds by these city-dwellers.

Peru: 'sensational' Inca find for British team in Andes

Discovery of sacred ancestor stones has archaeologists 'dancing a jig'
Dalya Alberge
The Observer, Sunday 5 December 2010

A British team of archaeologists on expedition in the Peruvian Andes has hailed as "sensational" the discovery of some of the most sacred objects in the Inca civilisation – three "ancestor stones", which were once believed to form a precious link between the heavens and the underworld.

The find, which was made on an isolated Andean mountainside, provoked joy among local specialists and the experts present from, among others, the British Museum, Reading University and Royal Holloway, University of London. No examples of the stones were thought to have survived until now.
"It was a very moving moment," said Dr Colin McEwan, the British Museum's head of the Americas, as he recalled seeing the stones for the first time.

Dr Frank Meddens, research associate of Royal Holloway, who was also on the expedition, said they had "danced a little jig on top of the mountain" after discovering the objects that they had only read about in 16th-century Spanish documents.

The Incas would have been just as overawed. The conical-shaped stones were among the most significant items in Inca society and religion. Key elements in ritual events, they were thought to facilitate a connection between different realms of the world – the celestial and the underworld of the ancestors – with the Inca king, as the divine ruler, acting as intermediary. And they were considered more precious than gold.

"This is a whole new category of object. It is nothing short of sensational," said McEwan of the three stones in red and white Andesite, a hard, granite-like rock, which were excavated some 2.5 metres beneath an Inca stone platform. The platform too was recently excavated and is a structure of distinctive stonework that once symbolised the imperial control of conquered territories.

The site – at Incapirca Waminan – is one of 20 undocumented high-altitude Inca ceremonial platforms explored by the archaeologists around the Ayacucho basin. Such sites were potent imperial symbols of religious and political authority as the Incas expanded outwards from Cuzco, a sacred city of temples and palaces in the central Peruvian Andes.

Ancestor stones represented deities, ancestors and the sun, and were imbued with supreme symbolic significance. They were greeted with incomprehension by Spanish chroniclers of the early 16th century, who sacrilegiously likened their shape to sugar loaves, pineapples and bowling pins. The insult, however, was returned: when the 16th-century Inca ruler Atahualpa was shown a copy of the Bible by the Conquistadors, he reacted with similar contempt.

According to Spanish sources, the stones were used in public solar rituals, sometimes draped in gold cloth and paraded. One witness wrote: "The stones… were held to be blessed and sacred."
Symbols of the ancestral essence of the Inca king, the objects were placed on display when the supreme leader was absent from Cuzco, the capital of the Inca people, in an attempt to demonstrate the perpetual presence and his power. The Incas believed their king to be a living god who ruled by divine right.

As the Incas had no system of writing, the significance of the archaeologists' unprecedented find is reinforced by the identification of ancestor stones in the decoration of a unique 16th-century Inca vessel (cocha) in the British Museum. Spanning 50cm in diameter, it bears a carved scene showing a central solar disc and two kneeling figures with their hands clasped as they honour an ancestor stone. They are flanked on either side by an Inca king and queen and high-ranking lords.

The Incas created a huge empire that stretched more than 2,400 miles along the length of the Andes and whose economy was based on taxed labour, with its people farming and herding animals, working in mines and producing goods such as clothing and pottery.

The sites for ceremonial platforms were chosen for their vistas of the snow-capped peaks, which were worshipped as mountain deities. It was at such sites that the Incas sacrificed children – the ceremony of capacocha – at moments of potential instability.

These structures also had sacred central spaces known as the ushnu, with a vertical opening into "the body of the earth" into which libations such as maize beer were poured. The ushnu platforms served as a stage from which the Inca king and his lords could preside over seasonal festivals and ceremonies.
