Ancient Egypt

The performing arts are arts such as music, dance, and drama which are performed for an audience. They are different from the visual arts, which involve the use of paint, canvas or various materials to create physical or static art objects. Performing arts include a range of disciplines which are performed in front of a live audience, including theatre, music, and dance.

Theatre, music, gymnastics, object manipulation, and other kinds of performances are present in all human cultures. The history of music and dance date to pre-historic times whereas circus skills date to at least Ancient Egypt. Many performing arts are performed professionally. Performance can be in purpose-built buildings, such as theatres and opera houses; on open air stages at festivals; on stages in tents, as in circuses; or on the street.

Egyptian astronomy started in prehistoric times, in the Predynastic Period. In the 5th millennium BCE, the stone circles at Nabta Playa may have made use of astronomical alignments. By the time the historical Dynastic Period began in the 3rd millennium BCE, the 365 day period of the Egyptian calendar was already in use, and the observation of stars was important in determining the annual flooding of the Nile.

The Egyptian pyramids were carefully aligned towards the pole star, and the temple of Amun-Re at Karnak was aligned on the rising of the midwinter Sun. Astronomy played a considerable part in fixing the dates of religious festivals and determining the hours of night, and temple astrologers were especially adept at watching the stars and observing the conjunctions and risings of the Sun, Moon, and planets, as well as the lunar phases.

Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into two – or three – major branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine.

The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Egypt and Mesopotamia (c. 3000–1200 BCE). Their contributions to mathematics, astronomy, and medicine entered and shaped the Greek natural philosophy of classical antiquity and later medieval scholarship, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes; while further advancements, including the introduction of the Hindu–Arabic numeral system, were made during the Golden Age of India and Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe during the Renaissance revived natural philosophy, which was later transformed by the Scientific Revolution that began in the 16th century as new ideas and discoveries departed from previous Greek conceptions and traditions. The scientific method soon played a greater role in the acquisition of knowledge, and in the 19th century, many of the institutional and professional features of science began to take shape, along with the changing of "natural philosophy" to "natural science".

The history of science covers the development of science from ancient times to the present. It encompasses all three major branches of science: natural, social, and formal. Protoscience, early sciences, and natural philosophies such as alchemy and astrology that existed during the Bronze Age, Iron Age, classical antiquity and the Middle Ages, declined during the early modern period after the establishment of formal disciplines of science in the Age of Enlightenment.

The earliest roots of scientific thinking and practice can be traced to Ancient Egypt and Mesopotamia during the 3rd and 2nd millennia BCE. These civilizations' contributions to mathematics, astronomy, and medicine influenced later Greek natural philosophy of classical antiquity, wherein formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Latin-speaking Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but continued to thrive in the Greek-speaking Byzantine Empire. Aided by translations of Greek texts, the Hellenistic worldview was preserved and absorbed into the Arabic-speaking Muslim world during the Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived the learning of natural philosophy in the West. Traditions of early science were also developed in ancient India and separately in ancient China, the Chinese model having influenced Vietnam, Korea and Japan before Western exploration. Among the Pre-Columbian peoples of Mesoamerica, the Zapotec civilization established their first known traditions of astronomy and mathematics for producing calendars, followed by other civilizations such as the Maya.

The history of Persian Egypt refers to the two periods when ancient Egypt was controlled by the Achaemenid Empire:

• Twenty-seventh Dynasty of Egypt (525–404 BC), established by the first Achaemenid conquest of Egypt.
• Thirty-first Dynasty of Egypt (343–332 BC), established by the second Achaemenid conquest of Egypt.

These two periods of satrapies were punctuated by a brief interval of Egyptian independence from 404 BC to 343 BC.

A cradle of civilization is a location and a culture where civilization was developed independently of other civilizations in other locations. A civilization is any complex society characterized by the development of the state, social stratification, urbanization, and symbolic systems of communication beyond signed or spoken languages (namely, writing systems and graphic arts).

Scholars generally acknowledge six cradles of civilization: Mesopotamia, Ancient Egypt, Ancient India and Ancient China are believed to be the earliest in Afro-Eurasia, while the Caral–Supe civilization of coastal Peru and the Olmec civilization of Mexico are believed to be the earliest in the Americas. All of the cradles of civilization depended upon agriculture for sustenance (except possibly Caral–Supe which may have depended initially on marine resources). All depended upon farmers producing an agricultural surplus to support the centralized government, political leaders, religious leaders, and public works of the urban centers of the early civilizations.

The pyramid of Khafre or of Chephren is the middle of the three Ancient Egyptian Pyramids of Giza, the second tallest and second largest of the group. It is the only pyramid out of the three that still has cladding at the top. It is the tomb of the Fourth-Dynasty Pharaoh Khafre (Chefren), who ruled c. 2558−2532 BC.

The Fourth Dynasty of ancient Egypt (notated Dynasty IV) is characterized as a "golden age" of the Old Kingdom of Egypt. Dynasty IV lasted from c. 2613 to c. 2498 BC. It was a time of peace and prosperity as well as one during which trade with other countries is officially documented.

The Fourth Dynasty heralded the height of the pyramid-building age. The peaceful rule of the Third Dynasty allowed artistic expressions to flourish. Building experiments done by King Sneferu led to the evolution of mastaba tombs into the smooth-sided pyramids like those seen on the Giza Plateau. No other period in Egyptian history equaled the accomplishments achieved during the Fourth Dynasty.

In ancient Egyptian history, the Old Kingdom is the period spanning c. 2700–2200 BC. It is also known as the "Age of the Pyramids" or the "Age of the Pyramid Builders", as it encompasses the reigns of the great pyramid-builders of the Fourth Dynasty, such as King Sneferu, under whom the art of pyramid-building was perfected, and the kings Khufu, Khafre and Menkaure, who commissioned the construction of the pyramids at Giza. Egypt attained its first sustained peak of civilization during the Old Kingdom, the first of three so-called "Kingdom" periods (followed by the Middle Kingdom and New Kingdom), which mark the high points of civilization in the lower Nile Valley.

The concept of an "Old Kingdom" as one of three "golden ages" was coined in 1845 by the German Egyptologist Baron von Bunsen, and its definition evolved significantly throughout the 19th and the 20th centuries. Not only was the last king of the Early Dynastic Period related to the first two kings of the Old Kingdom, but the "capital", the royal residence, remained at Ineb-Hedj, the Egyptian name for Memphis. The basic justification for separating the two periods is the revolutionary change in architecture accompanied by the effects on Egyptian society and the economy of large-scale building projects.

Giza (/ˈɡiːzə/; sometimes spelled Gizah, Gizeh, Geeza, Jiza; Arabic: الجيزة, romanized: al-Jīzah, pronounced [ald͡ʒiːzah], Egyptian Arabic: الجيزة el-Gīza [elˈgiːzæ]) is the third-largest city in Egypt by area after Cairo and Alexandria; and sixteenth-largest city in Africa by population. It is the capital of Giza Governorate with a total population of 4,458,135 as of 2023. It is located on the west bank of the Nile opposite central Cairo, and is a part of the Greater Cairo metropolis. Giza lies less than 30 kilometres (20 miles) north of Memphis (Men-nefer, today the village of Mit Rahina), which was the capital city of the unified Egyptian state during the reign of pharaoh Narmer, roughly 3100 BC.

Giza is most famous as the location of the Giza Plateau, the site of some of the most impressive ancient monuments in the world, including a complex of ancient Egyptian royal mortuary and sacred structures, among which are the Great Sphinx, the Great Pyramid of Giza, and a number of other large pyramids and temples and the Grand Egyptian Museum. Giza has always been a focal point in Egypt's history due to its location close to Memphis, the ancient pharaonic capital of the Old Kingdom.
