110-555: The ANS was the site of some of man's earliest geologic efforts, principally by the ancient Egyptians to extract gold from the rocks of Egypt and NE Sudan. This was the most easily worked of all metals and does not tarnish. All of the gold deposits in Egypt and northern Sudan were found and exploited by Egyptians. The earliest preserved geologic map was made in 1150 BCE to show the location of gold deposits in Eastern Egypt; it

220-639: A ceramic glaze known as faience , which was used well into the Roman Period to decorate cups, amulets, and figurines. During the last predynastic phase, the Naqada culture began using written symbols that eventually were developed into a full system of hieroglyphs for writing the ancient Egyptian language. The Early Dynastic Period was approximately contemporary to the early Sumerian - Akkadian civilization of Mesopotamia and of ancient Elam . The third-century   BC Egyptian priest Manetho grouped

330-469: A corvée system. Artists and craftsmen were of higher status than farmers, but they were also under state control, working in the shops attached to the temples and paid directly from the state treasury. Scribes and officials formed the upper class in ancient Egypt, known as the "white kilt class" in reference to the bleached linen garments that served as a mark of their rank. The upper class prominently displayed their social status in art and literature. Below

440-417: A nomarch , who was accountable to the vizier for his jurisdiction. The temples formed the backbone of the economy. Not only were they places of worship , but were also responsible for collecting and storing the kingdom's wealth in a system of granaries and treasuries administered by overseers , who redistributed grain and goods. Much of the economy was centrally organized and strictly controlled. Although

550-444: A balanced relationship between people and animals was an essential element of the cosmic order; thus humans, animals and plants were believed to be members of a single whole. Animals, both domesticated and wild , were therefore a critical source of spirituality, companionship, and sustenance to the ancient Egyptians. Cattle were the most important livestock; the administration collected taxes on livestock in regular censuses , and

660-607: A brief but spirited resurgence in the economy and culture, but in 525   BC, the Persian Empire, led by Cambyses II , began its conquest of Egypt, eventually defeating the pharaoh Psamtik III at the Battle of Pelusium . Cambyses II then assumed the formal title of pharaoh, but ruled Egypt from Iran, leaving Egypt under the control of a satrap . A few revolts against the Persians marked the 5th century   BC, but Egypt

770-710: A confident, eloquent style. The relief and portrait sculpture of the period captured subtle, individual details that reached new heights of technical sophistication. The last great ruler of the Middle Kingdom, Amenemhat III , allowed Semitic -speaking Canaanite settlers from the Near East into the Delta region to provide a sufficient labor force for his especially active mining and building campaigns. These ambitious building and mining activities, however, combined with severe Nile floods later in his reign, strained

880-542: A cornerstone in the history of human civilization. Nomadic modern human hunter-gatherers began living in the Nile valley through the end of the Middle Pleistocene some 120,000 years ago. By the late Paleolithic period, the arid climate of Northern Africa had become increasingly hot and dry, forcing the populations of the area to concentrate along the river region. In Predynastic and Early Dynastic times,

990-576: A large-scale building campaign to promote the god Amun , whose growing cult was based in Karnak . They also constructed monuments to glorify their own achievements, both real and imagined. The Karnak temple is the largest Egyptian temple ever built. Around 1350   BC, the stability of the New Kingdom was threatened when Amenhotep IV ascended the throne and instituted a series of radical and chaotic reforms. Changing his name to Akhenaten , he touted

1100-576: A period of economic and cultural renaissance known as the Middle Kingdom . The kings of the Middle Kingdom restored the country's stability and prosperity, thereby stimulating a resurgence of art, literature, and monumental building projects. Mentuhotep II and his Eleventh Dynasty successors ruled from Thebes, but the vizier Amenemhat I , upon assuming the kingship at the beginning of the Twelfth Dynasty around 1985   BC, shifted

1210-508: A piece of papyrus or an ostracon . A combination of favorable geographical features contributed to the success of ancient Egyptian culture, the most important of which was the rich fertile soil resulting from annual inundations of the Nile River. The ancient Egyptians were thus able to produce an abundance of food, allowing the population to devote more time and resources to cultural, technological, and artistic pursuits. Land management

1320-689: A queen who established herself as pharaoh, launched many building projects, including the restoration of temples damaged by the Hyksos, and sent trading expeditions to Punt and the Sinai. When Tuthmosis III died in 1425   BC, Egypt had an empire extending from Niya in north west Syria to the Fourth Cataract of the Nile in Nubia , cementing loyalties and opening access to critical imports such as bronze and wood . The New Kingdom pharaohs began

1430-608: A rival dynasty in the delta arose in Leontopolis , and Kushites threatened from the south. Around 727   BC the Kushite king Piye invaded northward, seizing control of Thebes and eventually the Delta, which established the 25th Dynasty . During the 25th Dynasty, Pharaoh Taharqa created an empire nearly as large as the New Kingdom 's. Twenty-fifth Dynasty pharaohs built, or restored, temples and monuments throughout

1540-662: A series of vassals who became known as the Saite kings of the Twenty-Sixth Dynasty . By 653   BC, the Saite king Psamtik I was able to oust the Assyrians with the help of Greek mercenaries, who were recruited to form Egypt's first navy . Greek influence expanded greatly as the city-state of Naucratis became the home of Greeks in the Nile Delta. The Saite kings based in the new capital of Sais witnessed

1650-407: Is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic , lithologic or paleontologic features ( facies ) that characterize it. Units must be mappable and distinct from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when

1760-679: Is associated with overthrust tectonics, but bear no relationship to the ancient gold mines. The superstructure consists of an ophiolite -like sequences with island arc volcanics , Hammamat sediments, and post orogenic granites . The ophiolite sequences range in age from 746 to 832 million years ( Ma ) and are mainly serpentite with elevated gold values of 25  parts per billion . The Hammamat sediments, common in Wadi Hammamat and referred to as "bekhen" stone, consist of greywackes and siltstones , which are slightly enriched in gold. The Hammamat sediments include dike intrusions and

1870-517: Is especially true for ancient gold exploitations oriented in north-northwest–south-southeast shear zones, such as the sites at Hammama, Abu Had North, Wad Atalla el-Mur, Atalla, Umm el Esh Sarga, Fawakhir, El-Sid, Umm Soleimat and Hamuda. Wadi el-Sid was the chief mining area for the New Kingdom of Egypt , with high gold grades of 30 grams per tonne in the mineralized quartz veins within sheared ophiolite sequences of serpentinite and metabasalt , imbricated with Hammamat sediments, in direct contact with

1980-503: Is known as the Turin papyrus . New gold discoveries have been found in Sudan, Eritrea, and Saudi Arabia. Pharonic Egyptians also quarried granite near Aswan and floated this down the Nile to be used as facing for the pyramids . The Greek name for Aswan, Syene ; is the type locality for the igneous rock syenite . The Romans followed this tradition and had many quarries especially in

2090-550: Is reputed to be the original source of King Solomon's legendary gold. Today, mining at Mahd adh Dhahab is conducted by the Saudi Arabian Mining Company, Ma'aden. Deposits of iron, tungsten, mineral sands, copper and phosphates have been found in many locations. Mining in the Eastern Desert of Egypt and Sudan is limited due to a shortage of water and infrastructure. The Arabian-Nubian Shield (ANS)

2200-562: Is the northern half of a great collision zone called the East African Orogeny . This collision zone formed near the end of Neoproterozoic time when East and West Gondwana collided to form the supercontinent Gondwana . The East African orogeny extends southward to the Mozambique Belt , and is a subset of the overall Pan-African orogeny . The assembly of Gondwana coincided with the breakup of Rodinia , closure of

2310-583: The Amarna Period . Around 1279   BC, Ramesses II , also known as Ramesses the Great, ascended the throne, and went on to build more temples, erect more statues and obelisks, and sire more children than any other pharaoh in history. A bold military leader, Ramesses II led his army against the Hittites in the Battle of Kadesh (in modern Syria ) and, after fighting to a stalemate, finally agreed to

2420-508: The Egyptian climate was much less arid than it is today . Large regions of Egypt were covered in treed savanna and traversed by herds of grazing ungulates . Foliage and fauna were far more prolific in all environs, and the Nile region supported large populations of waterfowl . Hunting would have been common for Egyptians, and this is also the period when many animals were first domesticated . By about 5500 BC , small tribes living in

2530-501: The Great Kenbet , over which the vizier or pharaoh presided. Plaintiffs and defendants were expected to represent themselves and were required to swear an oath that they had told the truth. In some cases, the state took on both the role of prosecutor and judge, and it could torture the accused with beatings to obtain a confession and the names of any co-conspirators. Whether the charges were trivial or serious, court scribes documented

2640-613: The Macedonians under Alexander the Great . The Greek Ptolemaic Kingdom , formed in the aftermath of Alexander's death, ruled until 30   BC, when, under Cleopatra , it fell to the Roman Empire and became a Roman province . Egypt remained under Roman control until 642 AD, when it was conquered by the Rashidun Caliphate . The success of ancient Egyptian civilization came partly from its ability to adapt to

2750-971: The Mouseion . The Lighthouse of Alexandria lit the way for the many ships that kept trade flowing through the city—as the Ptolemies made commerce and revenue-generating enterprises, such as papyrus manufacturing, their top priority. Hellenistic culture did not supplant native Egyptian culture, as the Ptolemies supported time-honored traditions in an effort to secure the loyalty of the populace. They built new temples in Egyptian style, supported traditional cults, and portrayed themselves as pharaohs. Some traditions merged, as Greek and Egyptian gods were syncretized into composite deities, such as Serapis , and classical Greek forms of sculpture influenced traditional Egyptian motifs. Despite their efforts to appease

2860-746: The Mozambique Ocean , and growth of the shield at 870 million years ago ( Ma ). This shield growth extended for the next 300 million years, and included island arc convergence and terrane suturing at 780 Ma, with final assembly by 550 Ma. At this time, the East African Orogen became a passive margin and the southern shore of the Paleo-Tethys Ocean . The shield is divided into crustal blocks or tectonostratigraphic terranes delineated by ophiolite shear zones or sutures. These terranes are paired across

2970-496: The Near East . The New Kingdom pharaohs established a period of unprecedented prosperity by securing their borders and strengthening diplomatic ties with their neighbours, including the Mitanni Empire, Assyria , and Canaan . Military campaigns waged under Tuthmosis I and his grandson Tuthmosis III extended the influence of the pharaohs to the largest empire Egypt had ever seen. Between their reigns, Hatshepsut ,

3080-772: The New Kingdom of the Late Bronze Age . Ancient Egypt reached the pinnacle of its power during the New Kingdom, ruling much of Nubia and a sizable portion of the Levant . After this period, it entered an era of slow decline. During the course of its history, ancient Egypt was invaded or conquered by a number of foreign powers, including the Hyksos , the Nubians , the Assyrians , the Achaemenid Persians , and

3190-584: The Nile . They also traded with Nubia to the south, the oases of the western desert to the west, and the cultures of the eastern Mediterranean and Near East to the east. The Naqada culture manufactured a diverse selection of material goods, reflective of the increasing power and wealth of the elite, as well as societal personal-use items, which included combs, small statuary, painted pottery, high quality decorative stone vases , cosmetic palettes , and jewelry made of gold, lapis, and ivory. They also developed

3300-415: The Nubians to the south of Egypt, but failed to defeat the Hyksos. That task fell to Kamose's successor, Ahmose I , who successfully waged a series of campaigns that permanently eradicated the Hyksos' presence in Egypt. He established a new dynasty and, in the New Kingdom that followed, the military became a central priority for the kings, who sought to expand Egypt's borders and attempted to gain mastery of

3410-606: The Persians and was welcomed by the Egyptians as a deliverer. The administration established by Alexander's successors, the Macedonian Ptolemaic Kingdom , was based on an Egyptian model and based in the new capital city of Alexandria . The city showcased the power and prestige of Hellenistic rule, and became a centre of learning and culture, that included the famous Library of Alexandria as part of

3520-707: The Pliocene , when a marine environment took over. As Rosemarie and Dietrich Klemm point out, "...gold deposits exploited in antiquity occur almost exclusively in the Neoproterozoic sequences of the ANS in the Eastern Desert in Egypt and Northern Sudan." The shield in this part of Africa consists of a cratonic African basement or "infrastructure", overlain by a pan-African overthrust "superstructure". The infrastructure consists of migmatite gneiss and gneiss domes such as Gebel Hafafit and Gebel Meatiq. The metamorphism

3630-537: The Red Sea , starting from the south, these include Nakfa (870–840 Ma) with Asir (785–720 Ma, 850–790 Ma), Haya (870–790 Ma) with Jiddah (870–760 Ma), Gabgaba (735–700 Ma) and Gebeit (832–810 Ma) with Hijaz (870–807 Ma), and Eastern Desert (810–720 Ma) with Midyan (780–710 Ma). In addition the Halfa (2600–1200 Ma, 750–718 Ma) and Bayuda (806 Ma) terranes are in

3740-619: The Thirtieth , proved to be the last native royal house of ancient Egypt, ending with the kingship of Nectanebo II . A brief restoration of Persian rule, sometimes known as the Thirty-First Dynasty , began in 343   BC, but shortly after, in 332   BC, the Persian ruler Mazaces handed Egypt over to Alexander the Great without a fight. In 332   BC, Alexander the Great conquered Egypt with little resistance from

3850-549: The Wadi Natrun for mummification , which also provided the gypsum needed to make plaster. Ore-bearing rock formations were found in distant, inhospitable wadis in the Eastern Desert and the Sinai, requiring large, state-controlled expeditions to obtain natural resources found there. There were extensive gold mines in Nubia , and one of the first maps known is of a gold mine in this region. The Wadi Hammamat

3960-451: The chaff from the grain, and the grain was then ground into flour, brewed to make beer, or stored for later use. The ancient Egyptians cultivated emmer and barley , and several other cereal grains, all of which were used to make the two main food staples of bread and beer. Flax plants, uprooted before they started flowering, were grown for the fibers of their stems. These fibers were split along their length and spun into thread, which

4070-581: The composite bow and the horse-drawn chariot . After retreating south, the native Theban kings found themselves trapped between the Canaanite Hyksos ruling the north and the Hyksos' Nubian allies, the Kushites , to the south. After years of vassalage, Thebes gathered enough strength to challenge the Hyksos in a conflict that lasted more than 30 years, until 1555   BC. The kings Seqenenre Tao II and Kamose were ultimately able to defeat

4180-758: The dacite to rhyolite Dokhan volcanics, which formed in the early stages of orogeny at 625–600 Ma. These volcanics include the Roman imperial porphyry quarries. The granite intrusions include two sequences, an older one 709–614 Ma, and a younger sequence at 596–544 Ma, which includes the Aswan granite at 565 Ma. The margin of the includes granodiorite and diorite , and most importantly, auriferous quartz veins . These veins mineralized from hydrothermal flow inside tectonic extensional gaps, or within cavities from shearing. These characteristics were exploited by New Kingdom of Egypt prospectors. This

4290-458: The earliest known peace treaty , made with the Hittites . Ancient Egypt has left a lasting legacy. Its art and architecture were widely copied, and its antiquities were carried off to be studied, admired or coveted in the far corners of the world. Its monumental ruins have inspired the imaginations of travelers and writers for millennia. A newfound respect for antiquities and excavations in

4400-478: The tonalite margins of the Fawakhir granite pluton . The ophiolite nappe dates from 850 to 770 Ma, while the Fawakhir pluton dates from 574 Ma. These gold-rich veins are oriented according to post-tectonic extension, something the Egyptian prospectors understood. The well of Umm el-Fawakhir area includes a Large Ptolemaic settlement and round stone mills dating from the Roman or Early Arab Period to

4510-523: The vizier and his court for redress. Although slaves were mostly used as indentured servants, they were able to buy and sell their servitude, work their way to freedom or nobility, and were usually treated by doctors in the workplace. Both men and women had the right to own and sell property, make contracts, marry and divorce, receive inheritance, and pursue legal disputes in court. Married couples could own property jointly and protect themselves from divorce by agreeing to marriage contracts, which stipulated

4620-709: The 600 km (370 mi) long and 5–30 km (3–19 mi) wide Hulayfah–Ad-Dafinah–Ruwah Suture formed between the Afif Terrance and terranes to the southwest. Simultaneously, the Halaban Suture formed between the Afif and Ad-Dawadimi Terranes as a nappe of Halaban ophiolite thrust westward. In addition, the Al-Amar Suture, consisting of the Al-Amar Fault zone with ophiolite lenses, between

4730-866: The Ad-Dawadimi and Ar-Rayan Terranes, while the Nabitah Fault Zone formed in Asir Terrane. The final amalgamation event occurred 650–600 Ma, when the Keraf Suture, consisting of ophiolite folded and sheared rocks, formed between the Bayuda–Halfa and GebeitGabgaba Terranes. Post-amalgamation events include the formation of the Huqf Supergroup (732–540 Ma) in Oman and western Saudi Arabia, which accumulated in basement basins,

4840-672: The Ar-Rika–Qazaz Shear Zone (640–610 Ma) within the Najd Fault System, and the Oko Shear Zone (700–560 Ma). A number of features have been ascribed to late stage extensional tectonics including a widespread northeast trending dyke swarm, northeast–southwest trending normal faults and northwest–southeast trending sedimentary basins filled with post-orogenic molasse deposits Crustal weaknesses before 500 Ma influenced continental rifting , as

4950-665: The Arabian peninsula moved away from Africa, and the formation of the Red Sea Basin at the start of the Oligocene . By then, some of the Paleozoic and Mesozoic rocks had been eroded, if ever deposited. In fact, the 1,200 km (750 mi) wide ANS orogenic belt, has a present-day layered crustal structure, with a uniform Moho depth of 35–45 km (22–28 mi). Post-rift deposition of evaporites occurred until

5060-572: The Assyrians. The effects of external threats were exacerbated by internal problems such as corruption, tomb robbery, and civil unrest . After regaining their power, the high priests at the temple of Amun in Thebes accumulated vast tracts of land and wealth, and their expanded power splintered the country during the Third Intermediate Period. Following the death of Ramesses XI in 1078   BC, Smendes assumed authority over

5170-476: The Christian emperor Theodosius introduced legislation that banned pagan rites and closed temples. Alexandria became the scene of great anti-pagan riots with public and private religious imagery destroyed. As a consequence, Egypt's native religious culture was continually in decline. While the native population continued to speak their language , the ability to read hieroglyphic writing slowly disappeared as

5280-435: The Delta, seized control of Egypt and established their capital at Avaris , forcing the former central government to retreat to Thebes . The king was treated as a vassal and expected to pay tribute. The Hyksos ('foreign rulers') retained Egyptian models of government and identified as kings, thereby integrating Egyptian elements into their culture. They and other invaders introduced new tools of warfare into Egypt, most notably

5390-453: The Egyptians, the Ptolemies were challenged by native rebellion, bitter family rivalries, and the powerful mob of Alexandria that formed after the death of Ptolemy IV . In addition, as Rome relied more heavily on imports of grain from Egypt, the Romans took great interest in the political situation in the country. Continued Egyptian revolts, ambitious politicians, and powerful opponents from

5500-451: The Greeks towards the Egyptians, some traditions such as mummification and worship of the traditional gods continued. The art of mummy portraiture flourished, and some Roman emperors had themselves depicted as pharaohs, though not to the extent that the Ptolemies had. The former lived outside Egypt and did not perform the ceremonial functions of Egyptian kingship. Local administration became Roman in style and closed to native Egyptians. From

5610-441: The Jiddah–Haya and Hijaz–Gebeit Terranes. Then between 750 and 660 Ma, the Atmur–Delgo Suture formed as Halfa Terrane ophiolite nappes were thrust onto the Bayuda Terrane. Simultaneously, the Allaqi–Heiani–Sol and Hamed–Onib–Yanbu Suture formed, consisting of nappes and portions of ophiolite along an east-trending shear zone between the Gebeit–Hijaz and Eastern Desert Terrane and Midyan Terranes. Between 680 and 640 Ma,

5720-485: The Late Period, the worship of the gods in their animal form was extremely popular, such as the cat goddess Bastet and the ibis god Thoth , and these animals were kept in large numbers for the purpose of ritual sacrifice. Egypt is rich in building and decorative stone, copper and lead ores, gold, and semiprecious stones. These natural resources allowed the ancient Egyptians to build monuments, sculpt statues, make tools, and fashion jewelry . Embalmers used salts from

5830-452: The Late Period. There is also evidence to suggest that elephants were briefly used in the Late Period but largely abandoned due to lack of grazing land. Cats , dogs, and monkeys were common family pets, while more exotic pets imported from the heart of Africa, such as Sub-Saharan African lions , were reserved for royalty. Herodotus observed that the Egyptians were the only people to keep their animals with them in their houses. During

5940-417: The Near East made this situation unstable, leading Rome to send forces to secure the country as a province of its empire. Egypt became a province of the Roman Empire in 30   BC, following the defeat of Mark Antony and Ptolemaic Queen Cleopatra VII by Octavian (later Emperor Augustus) in the Battle of Actium . The Romans relied heavily on grain shipments from Egypt, and the Roman army , under

6050-451: The Nile valley had developed into a series of cultures demonstrating firm control of agriculture and animal husbandry , and identifiable by their pottery and personal items, such as combs, bracelets, and beads. The largest of these early cultures in upper (Southern) Egypt was the Badarian culture , which probably originated in the Western Desert ; it was known for its high-quality ceramics, stone tools , and its use of copper. The Badari

The ancient Egyptians used donkeys and oxen as beasts of burden , and they were responsible for plowing the fields and trampling seed into the soil. The slaughter of a fattened ox was also a central part of an offering ritual. Horses were introduced by the Hyksos in the Second Intermediate Period . Camels, although known from the New Kingdom, were not used as beasts of burden until

Under the direction of the vizier , state officials collected taxes, coordinated irrigation projects to improve crop yield , drafted peasants to work on construction projects, and established a justice system to maintain peace and order. With the rising importance of central administration in Egypt, a new class of educated scribes and officials arose who were granted estates by

With the kings having secured the country militarily and politically and with vast agricultural and mineral wealth at their disposal, the nation's population, arts, and religion flourished. In contrast to elitist Old Kingdom attitudes towards the gods, the Middle Kingdom displayed an increase in expressions of personal piety. Middle Kingdom literature featured sophisticated themes and characters written in

6710-499: The administration, aside from the royal high priestesses, apparently served only secondary roles in the temples (not much data for many dynasties), and were not so probably to be as educated as men. The head of the legal system was officially the pharaoh, who was responsible for enacting laws, delivering justice, and maintaining law and order, a concept the ancient Egyptians referred to as Ma'at . Although no legal codes from ancient Egypt survive, court documents show that Egyptian law

6820-507: The ancient Egyptians did not use coinage until the Late period , they did use a type of money-barter system, with standard sacks of grain and the deben , a weight of roughly 91 grams (3 oz) of copper or silver, forming a common denominator. Workers were paid in grain; a simple laborer might earn 5 + 1 ⁄ 2  sacks (200 kg or 400 lb) of grain per month, while a foreman might earn 7 + 1 ⁄ 2  sacks (250 kg or 550 lb). Prices were fixed across

A group is a set of two or more formations that share certain lithological characteristics. A group may be made up of different formations in different geographical areas and individual formations may appear in more than one group. Groups are occasionally divided into subgroups, but subgroups are not mentioned in

Not all formations are subdivided in this way and even where they are recognized, they may only form part of the formation. A member need not be mappable at the same scale as a formation. Formations are the primary units used in the subdivision of a sequence and may vary in scale from tens of centimetres to kilometres. They should be distinct lithologically from other formations, although

Punishment for minor crimes involved either imposition of fines, beatings, facial mutilation, or exile, depending on the severity of the offense. Serious crimes such as murder and tomb robbery were punished by execution, carried out by decapitation, drowning, or impaling the criminal on a stake. Punishment could also be extended to

7370-419: The conditions of the Nile River valley for agriculture . The predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which supported a more dense population, and social development and culture. With resources to spare, the administration sponsored mineral exploitation of the valley and surrounding desert regions, the early development of an independent writing system ,

7480-401: The control of a prefect appointed by the emperor, quelled rebellions, strictly enforced the collection of heavy taxes, and prevented attacks by bandits, which had become a notorious problem during the period. Alexandria became an increasingly important center on the trade route with the orient, as exotic luxuries were in high demand in Rome. Although the Romans had a more hostile attitude than

Regional governors could not rely on the king for help in times of crisis, and the ensuing food shortages and political disputes escalated into famines and small-scale civil wars. Yet despite difficult problems, local leaders, owing no tribute to the king, used their new-found independence to establish a thriving culture in the provinces. Once in control of their own resources,

The procedure was to ask the god a "yes" or "no" question concerning the right or wrong of an issue. The god, carried by a number of priests, rendered judgement by choosing one or the other, moving forward or backward, or pointing to one of the answers written on

7920-411: The early modern period by Europeans and Egyptians has led to the scientific investigation of Egyptian civilization and a greater appreciation of its cultural legacy. The Nile has been the lifeline of its region for much of human history. The fertile floodplain of the Nile gave humans the opportunity to develop a settled agricultural economy and a more sophisticated, centralized society that became

During this decline, the Canaanite settlers began to assume greater control of the Delta region, eventually coming to power in Egypt as the Hyksos . Around 1785   BC, as the power of the Middle Kingdom kings weakened, a Western Asian people called the Hyksos , who had already settled in

8140-424: The fertile delta region, as well as the lucrative and critical trade routes to the Levant . The increasing power and wealth of the kings during the early dynastic period was reflected in their elaborate mastaba tombs and mortuary cult structures at Abydos, which were used to celebrate the deified king after his death. The strong institution of kingship developed by the kings served to legitimize state control over

8250-524: The financial obligations of the husband to his wife and children should the marriage end. Compared with their counterparts in ancient Greece, Rome, and even more modern places around the world, ancient Egyptian women had a greater range of personal choices, legal rights, and opportunities for achievement. Women such as Hatshepsut and Cleopatra VII even became pharaohs, while others wielded power as Divine Wives of Amun . Despite these freedoms, ancient Egyptian women did not often take part in official roles in

8360-703: The first 1,100 m (3,600 ft) of which include glaciomarine deposits with diamictites and dropstones from the Sturtian and Marinoan glaciations. Gneiss belts and domes forming in the Late Neoproterozoic include the Kirsh gneiss in the Arabian shield and the Meatiq gneiss dome in the Eastern Desert. Late Neoproterozoic shear zones include the Hamisana Shear Zone (665–610 Ma),

8470-613: The first recorded peace treaty , around 1258   BC. Egypt's wealth, however, made it a tempting target for invasion, particularly by the Libyan Berbers to the west, and the Sea Peoples , a conjectured confederation of seafarers from the Aegean Sea . Initially, the military was able to repel these invasions, but Egypt eventually lost control of its remaining territories in southern Canaan , much of it falling to

8580-427: The floodwaters had receded, the growing season lasted from October to February. Farmers plowed and planted seeds in the fields, which were irrigated with ditches and canals. Egypt received little rainfall, so farmers relied on the Nile to water their crops. From March to May, farmers used sickles to harvest their crops, which were then threshed with a flail to separate the straw from the grain. Winnowing removed

8690-417: The following centuries international traders came to rely on coinage. Egyptian society was highly stratified, and social status was expressly displayed. Farmers made up the bulk of the population, but agricultural produce was owned directly by the state, temple, or noble family that owned the land. Farmers were also subject to a labor tax and were required to work on irrigation or construction projects in

8800-412: The government, who relied on a bureaucracy of officials to manage his affairs. In charge of the administration was his second in command, the vizier , who acted as the king's representative and coordinated land surveys, the treasury, building projects, the legal system, and the archives . At a regional level, the country was divided into as many as 42 administrative regions called nomes each governed by

8910-411: The king in payment for their services. Kings also made land grants to their mortuary cults and local temples , to ensure that these institutions had the resources to worship the king after his death. Scholars believe that five centuries of these practices slowly eroded the economic vitality of Egypt, and that the economy could no longer afford to support a large centralized administration. As the power of

9020-593: The kingdom's capital to the city of Itjtawy , located in Faiyum . From Itjtawy, the kings of the Twelfth Dynasty undertook a far-sighted land reclamation and irrigation scheme to increase agricultural output in the region. Moreover, the military reconquered territory in Nubia that was rich in quarries and gold mines, while laborers built a defensive structure in the Eastern Delta, called the " Walls of

9130-588: The kings diminished, regional governors called nomarchs began to challenge the supremacy of the office of king. This, coupled with severe droughts between 2200 and 2150   BC, is believed to have caused the country to enter the 140-year period of famine and strife known as the First Intermediate Period. After Egypt's central government collapsed at the end of the Old Kingdom, the administration could no longer support or stabilize

9240-566: The land, labor, and resources that were essential to the survival and growth of ancient Egyptian civilization. Major advances in architecture, art, and technology were made during the Old Kingdom , fueled by the increased agricultural productivity and resulting population growth, made possible by a well-developed central administration. Some of ancient Egypt's crowning achievements, the Giza pyramids and Great Sphinx , were constructed during

9350-497: The long line of kings from Menes to his own time into 30 dynasties, a system still used today. He began his official history with the king named "Meni" (or Menes in Greek), who was believed to have united the two kingdoms of Upper and Lower Egypt . The transition to a unified state happened more gradually than ancient Egyptian writers represented, and there is no contemporary record of Menes. Some scholars now believe, however, that

9460-464: The mid-first century AD, Christianity took root in Egypt and it was originally seen as another cult that could be accepted. However, it was an uncompromising religion that sought to win converts from the pagan Egyptian and Greco-Roman religions and threatened popular religious traditions. This led to the persecution of converts to Christianity, culminating in the great purges of Diocletian starting in 303, but eventually Christianity won out. In 391,

9570-528: The mythical Menes may have been the king Narmer , who is depicted wearing royal regalia on the ceremonial Narmer Palette, in a symbolic act of unification. In the Early Dynastic Period, which began about 3000   BC, the first of the Dynastic kings solidified control over lower Egypt by establishing a capital at Memphis , from which he could control the labor force and agriculture of

9680-405: The nobility were the priests, physicians, and engineers with specialized training in their field. It is unclear whether slavery as understood today existed in ancient Egypt; there is difference of opinions among authors. The ancient Egyptians viewed men and women, including people from all social classes, as essentially equal under the law, and even the lowliest peasant was entitled to petition

9790-682: The north, while a rival clan based in Thebes , the Intef family , took control of Upper Egypt in the south. As the Intefs grew in power and expanded their control northward, a clash between the two rival dynasties became inevitable. Around 2055   BC the northern Theban forces under Nebhepetre Mentuhotep II finally defeated the Herakleopolitan rulers, reuniting the Two Lands. They inaugurated

9900-676: The northern part of Egypt, ruling from the city of Tanis . The south was effectively controlled by the High Priests of Amun at Thebes , who recognized Smendes in name only. During this time, Libyans had been settling in the western delta, and chieftains of these settlers began increasing their autonomy. Libyan princes took control of the delta under Shoshenq I in 945   BC, founding the so-called Libyan or Bubastite dynasty that would rule for some 200 years. Shoshenq also gained control of southern Egypt by placing his family members in important priestly positions. Libyan control began to erode as

10010-500: The northern part of the Eastern Desert of Egypt where porphyry and granite were mined and shaped for shipment. Precious and industrial metals, including gold, silver, copper, zinc, tin, and lead, have been mined in Saudi Arabia for at least 5,000 years. The most productive mine in Saudi Arabia, Mahd adh Dhahab ("Cradle of Gold"), has been periodically exploited for its mineral wealth for hundreds or even thousands of years and

10120-462: The organization of collective construction and agricultural projects, trade with surrounding regions, and a military intended to assert Egyptian dominance. Motivating and organizing these activities was a bureaucracy of elite scribes , religious leaders, and administrators under the control of a pharaoh , who ensured the cooperation and unity of the Egyptian people in the context of an elaborate system of religious beliefs . The many achievements of

10230-751: The oval stone mills of the New Kingdom. Even fist hammers from the Old/Middle Kingdom are present. Tailings were reworked by the Louison Company from the 1930s until 1956. Ancient Egyptians Ancient Egypt was a civilization of ancient Northeast Africa . It was concentrated along the lower reaches of the Nile River , situated within the contemporary territory of modern-day Egypt . Ancient Egyptian civilization followed prehistoric Egypt and coalesced around 3100   BC (according to conventional Egyptian chronology ) with

10340-557: The political unification of Upper and Lower Egypt under pharaoh or king Menes (often identified with Narmer ). The history of ancient Egypt unfolded as a series of stable kingdoms interspersed by periods of relative instability known as "Intermediate Periods". The various kingdoms fall into one of three categories: the Old Kingdom of the Early Bronze Age , the Middle Kingdom of the Middle Bronze Age , or

10450-528: The previously obscure sun deity Aten as the supreme deity , suppressed the worship of most other deities, and moved the capital to the new city of Akhetaten (modern-day Amarna ). He was devoted to his new religion and artistic style . After his death, the cult of the Aten was quickly abandoned and the traditional religious order restored. The subsequent pharaohs, Tutankhamun , Ay , and Horemheb , worked to erase all mention of Akhenaten's heresy, now known as

10560-621: The provinces became economically richer—which was demonstrated by larger and better burials among all social classes. In bursts of creativity, provincial artisans adopted and adapted cultural motifs formerly restricted to the royalty of the Old Kingdom, and scribes developed literary styles that expressed the optimism and originality of the period. Free from their loyalties to the king, local rulers began competing with each other for territorial control and political power . By 2160   BC, rulers in Herakleopolis controlled Lower Egypt in

10670-718: The role of the Egyptian temple priests and priestesses diminished. The temples themselves were sometimes converted to churches or abandoned to the desert. In the fourth century, as the Roman Empire divided, Egypt found itself in the Eastern Empire with its capital at Constantinople . In the waning years of the Empire, Egypt fell to the Sasanian Persian army in the Sasanian conquest of Egypt (618–628). It

10780-597: The sandstone component exceeds 75%". Sequences of sedimentary and volcanic rocks are subdivided on the basis of their shared or associated lithology . Formally identified lithostratigraphic units are structured in a hierarchy of lithostratigraphic rank , higher rank units generally comprising two or more units of lower rank. Going from smaller to larger in rank, the main lithostratigraphic ranks are bed, member, formation, group and supergroup. Formal names of lithostratigraphic units are assigned by geological surveys . Units of formation or higher rank are usually named for

10890-402: The size of a herd reflected the prestige and importance of the estate or temple that owned them. In addition to cattle, the ancient Egyptians kept sheep, goats, and pigs. Poultry , such as ducks, geese, and pigeons, were captured in nets and bred on farms, where they were force-fed with dough to fatten them. The Nile provided a plentiful source of fish . Bees were also domesticated from at least

11000-549: The two states became inevitable. Between 671 and 667   BC the Assyrians began the Assyrian conquest of Egypt . The reigns of both Taharqa and his successor, Tanutamun , were filled with constant conflict with the Assyrians, against whom Egypt enjoyed several victories. Ultimately, the Assyrians pushed the Kushites back into Nubia, occupied Memphis, and sacked the temples of Thebes . The Assyrians left control of Egypt to

11110-467: The unit's type location , and the formal name usually also states the unit's rank or lithology. A lithostratigraphic unit may have a change in rank over a some distance; a group may thin to a formation in another region and a formation may reduce in rank for member or bed as it "pinches out". A bed is a lithologically distinct layer within a member or formation and is the smallest recognisable stratigraphic unit. These are not normally named, but may be in

11220-656: The western portion of the shield, and the Hulayfah (720 Ma), Ha'il (740 Ma), Afif (750–695 Ma, 840–820 Ma, 1860–1660 Ma), Ad-Dawadimi (695–680 Ma), and Ar-Rayn (667 Ma) terranes in the eastern portion. Key amalgamation events, starting 780–760 Ma, with the formation of the Tabalah–Tarj Shear Zone, the gneiss Afaf Belt, and the 600 km (370 mi) long and 565 km (351 mi) wide Bi'r Umq and Nakasib Suture (780–760 Ma), an ophiolite-decorated fold-shear zone, between

11330-517: Was a notable source of granite, greywacke , and gold. Flint was the first mineral collected and used to make tools, and flint handaxes are the earliest pieces of evidence of habitation in the Nile valley. Nodules of the mineral were carefully flaked to make blades and arrowheads of moderate hardness and durability even after copper was adopted for this purpose. Ancient Egyptians were among the first to use minerals such as sulfur as cosmetic substances. Stratigraphic unit A stratigraphic unit

11440-542: Was also the beginning of trade with Mesopotamia , which continued into the early dynastic period and beyond. Over a period of about 1,000 years, the Naqada culture developed from a few small farming communities into a powerful civilization whose leaders were in complete control of the people and resources of the Nile valley. Establishing a power center at Nekhen (in Greek, Hierakonpolis), and later at Abydos , Naqada III leaders expanded their control of Egypt northwards along

11550-423: Was based on a common-sense view of right and wrong that emphasized reaching agreements and resolving conflicts rather than strictly adhering to a complicated set of statutes. Local councils of elders, known as Kenbet in the New Kingdom, were responsible for ruling in court cases involving small claims and minor disputes. More serious cases involving murder, major land transactions, and tomb robbery were referred to

11660-421: Was crucial in ancient Egypt because taxes were assessed based on the amount of land a person owned. Farming in Egypt was dependent on the cycle of the Nile River. The Egyptians recognized three seasons: Akhet (flooding), Peret (planting), and Shemu (harvesting). The flooding season lasted from June to September, depositing on the river's banks a layer of mineral-rich silt ideal for growing crops. After

11770-541: Was followed by the Naqada culture : the Naqada I ( Amratian ), the Naqada II ( Gerzeh ), and Naqada III ( Semainean ). These brought a number of technological improvements. As early as the Naqada I Period, predynastic Egyptians imported obsidian from Ethiopia , used to shape blades and other objects from flakes . Mutual trade with the Levant was established during Naqada II ( c.  3600–3350 BC ); this period

11880-577: Was never able to overthrow the Persians until the end of the century. Following its annexation by Persia, Egypt was joined with Cyprus and Phoenicia in the sixth satrapy of the Achaemenid Persian Empire . This first period of Persian rule over Egypt, also known as the Twenty-Seventh Dynasty , ended in 402   BC, when Egypt regained independence under a series of native dynasties. The last of these dynasties,

11990-476: Was then recaptured by the Byzantine emperor Heraclius (629–639), and was finally captured by Muslim Rashidun army in 639–641, marking the end of both Byzantine rule and of the period typically considered Ancient Egypt. The pharaoh was the absolute monarch of the country and, at least in theory, wielded complete control of the land and its resources. The king was the supreme military commander and head of

12100-420: Was used to weave sheets of linen and to make clothing. Papyrus growing on the banks of the Nile River was used to make paper. Vegetables and fruits were grown in garden plots, close to habitations and on higher ground, and had to be watered by hand. Vegetables included leeks, garlic, melons, squashes, pulses, lettuce, and other crops, in addition to grapes that were made into wine. The Egyptians believed that
