Egyptian pyramids in the context of Pyramid

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.

The Memphite Necropolis (or Pyramid Fields) is a series of ancient Egyptian funerary complexes occupying a 30-kilometer (19 mi) stretch on the Western Desert plateau near the ancient capital of Memphis (modern day Giza).

It includes the pyramid complexes of Giza, Abusir, Saqqara and Dahshur and is recognized by UNESCO as a World Heritage Site. In addition to many of the pyramids of the Old Kingdom, the necropolis is also populated with many tombs (e.g. mastabas), temples, and funerary artifacts. However, the site’s historical importance is not limited to these features. The necropolis also includes sites such as Heit al-Ghurab. Located in the southeastern area of the Giza Plateau, the site includes the village where craftsmen working on the tombs and pyramids would have lived. As a result of its status as physical and chronological behemoth, the Memphite Necropolis stands as a valuable tool to historians in understanding changes in Egyptian funerary culture and architecture across time.

Abusir (Arabic: ابو صير  Egyptian Arabic pronunciation: [æbuˈsˤiːɾ]; Egyptian pr wsjr; Coptic: ⲃⲟⲩⲥⲓⲣⲓ busiri, "the resting place of Osiris"; Ancient Greek: Βούσιρις) is the name given to an ancient Egyptian archaeological pyramid complex comprising the ruins of 4 kings' pyramids dating to the Old Kingdom period, and is part of the Pyramid Fields of the Memphis and its Necropolis UNESCO World Heritage Site.

The pyramid complex is named after the neighbouring village of Abusir, in the markaz (county) of Badrashin, Giza. The Abusir pyramid complex is located on the Western Desert plateau at the edge of the cultivated plain, with the Giza Pyramids to its north, and Saqqara to its south, and served as one of the main elite cemeteries for the ancient Egyptian capital city of Memphis. Several other villages in northern and southern Egypt are named Abusir or Busiri.

In architecture, a folly is a building constructed primarily for decoration, but suggesting through its appearance some other purpose, or of such extravagant appearance that it transcends the range of usual garden buildings.

Eighteenth-century English landscape gardening and French landscape gardening often featured mock Roman temples, symbolising classical virtues. Other 18th-century garden follies imitated Chinese temples, Egyptian pyramids, ruined medieval castles, abbeys, or Tatar tents, to represent different continents or historical eras. Sometimes they represented rustic villages, mills and cottages, to symbolise rural virtues. Many follies, particularly during times of famine, such as the Great Famine in Ireland, were built as a form of poor relief, to provide employment for peasants and unemployed artisans.

Stonemasonry or stonecraft is the creation of buildings, structures, and sculpture using stone as the primary material. Stonemasonry is the craft of shaping and arranging stones, often together with mortar and even the ancient lime mortar, to wall or cover formed structures.

The basic tools, methods and skills of the banker mason have existed as a trade for thousands of years. It is one of the oldest activities and professions in human history. Many of the long-lasting, ancient shelters, temples, monuments, artifacts, fortifications, roads, bridges, and entire cities were built of stone. Famous works of stonemasonry include Göbekli Tepe, the Egyptian pyramids, the Taj Mahal, Cusco's Incan Wall, Taqwesan, Easter Island's statues, Angkor Wat, Borobudur, Tihuanaco, Tenochtitlan, Persepolis, the Parthenon, Stonehenge, the Great Wall of China, the Mesoamerican pyramids, Chartres Cathedral, and the Stari Most.

The Tempest Stele (alt. Storm Stele) was erected by pharaoh Ahmose I early in the 18th Dynasty of Egypt, c. 1550 BCE. The stele describes a great storm striking Egypt during this time, destroying tombs, temples and pyramids in the Theban region and the work of restoration ordered by the king.

A pyramidion (plural: pyramidia) is the capstone of an Egyptian pyramid or the upper section of an obelisk. Speakers of the Ancient Egyptian language referred to pyramidia as benbenet and associated the pyramid as a whole with the sacred benben stone.

Pyramidia were usually made of limestone, sandstone, basalt or granite, and were sometimes covered with plates of copper, gold or electrum. From the Middle Kingdom onward, they were often "inscribed with royal titles and religious symbols".

Funerary art is any work of art forming, or placed in, a repository for the remains of the dead. The term encompasses a wide variety of forms, including cenotaphs ("empty tombs"), tomb-like monuments which do not contain human remains, and communal memorials to the dead, such as war memorials, which may or may not contain remains, and a range of prehistoric megalithic constructs. Funerary art may serve many cultural functions. It can play a role in burial rites, serve as an article for use by the dead in the afterlife, and celebrate the life and accomplishments of the dead, whether as part of kinship-centred practices of ancestor veneration or as a publicly directed dynastic display. It can also function as a reminder of the mortality of humankind, as an expression of cultural values and roles, and help to propitiate the spirits of the dead, maintaining their benevolence and preventing their unwelcome intrusion into the lives of the living.

The deposit of objects with an apparent aesthetic intention is found in almost all cultures – Hindu culture, which has little, is a notable exception. Many of the best-known artistic creations of past cultures – from the Egyptian pyramids and the Tutankhamun treasure, to the Terracotta Army surrounding the tomb of Qin Shi Huang, the Mausoleum of Halicarnassus, the Sutton Hoo ship burial and the Taj Mahal – are tombs or objects found in and around them. In most instances, specialized funeral art was produced for the powerful and wealthy, although the burials of ordinary people might include simple monuments and grave goods, usually from their possessions.

The pyramid of Djedefre is Egypt's northernmost pyramid. Believed to have been built by Djedefre, son and successor to king Khufu, it consists today mostly of ruins located at Abu Rawash in Egypt. Excavation report on the pyramid complex was published in 2011.

A nummulite is a large lenticular fossil, characterised by its numerous coils, subdivided by septa into chambers. They are the shells of the fossil and present-day marine protozoan Nummulites, a type of foraminiferan. Nummulites commonly vary in diameter from 13 to 50 mm (0.51 to 1.97 in) and are common in Eocene to Miocene marine rocks, particularly around southwest Asia and the Mediterranean in the area that once constituted the Tethys Ocean, such as Eocene limestones from Egypt or from Pakistan. Fossils up to six inches wide are found in the Middle Eocene rocks of Turkey. They are valuable as index fossils.

The ancient Egyptians used nummulite shells as coins and the pyramids were constructed using limestone that contained nummulites. It is not surprising then that the name Nummulites is a diminutive form of the Latin nummulus 'little coin', a reference to their shape.

Spanning over three thousand years, ancient Egypt was not one stable civilization but in constant change and upheaval, commonly split into periods by historians. Likewise, ancient Egyptian architecture is not one style, but a set of styles differing over time but with some commonalities.

The best known example of ancient Egyptian architecture are the Egyptian pyramids and Sphinx, while excavated temples, palaces, tombs, and fortresses have also been studied. Most buildings were built of locally available mud brick and limestone by paid laborers and craftsmen. Monumental buildings were built using the post and lintel method of construction. Many buildings were aligned astronomically. Columns were typically adorned with capitals decorated to resemble plants important to Egyptian civilization, such as the papyrus plant.

Mesoamerican pyramids form a prominent part of ancient Mesoamerican architecture. Although similar in some ways to Egyptian pyramids, these New World structures have flat tops (many with temples on the top) and stairs ascending their faces, more similar to ancient Mesopotamian Ziggurats. Most pyramids had square bases, but there were also pyramids of other shapes, including rounded ones. The largest pyramid in the world by volume is the Great Pyramid of Cholula, in the east-central Mexican state of Puebla. The builders of certain classic Mesoamerican pyramids have decorated them copiously with stories about the Hero Twins, the feathered serpent Quetzalcoatl, Mesoamerican creation myths, ritualistic sacrifice, etc. written in the form of Maya script on the rises of the steps of the pyramids, on the walls, and on the sculptures contained within.

Newgrange (Irish: Sí an Bhrú) is a prehistoric monument in County Meath in Ireland, placed on a rise overlooking the River Boyne, eight kilometres (five miles) west of the town of Drogheda. It is an exceptionally grand passage tomb built during the Neolithic Period, around 3100 BC, making it older than Stonehenge and the Egyptian pyramids. Newgrange is the main monument in the Brú na Bóinne complex, a World Heritage Site that also includes the passage tombs of Knowth and Dowth, as well as other henges, burial mounds and standing stones.

Newgrange consists of a large circular mound with an inner stone passageway and cruciform chamber. Burnt and unburnt human bones, and possible grave goods or votive offerings, were found in this chamber. The monument has a striking façade made mostly of white quartz cobblestones, and it is ringed by engraved kerbstones. Many of the larger stones of Newgrange are covered in megalithic art. The mound is also ringed by a stone circle. Some of the material that makes up the monument came from as far as the Mournes and Wicklow Mountains. There is no agreement about its purpose, but it is believed it had religious significance. It is aligned so that the rising sun on the winter solstice shines through a "roofbox" above the entrance and floods the inner chamber. Several other passage tombs in Ireland are aligned with solstices and equinoxes, and Cairn G at Carrowkeel has a similar "roofbox". Newgrange shares similarities with some other Neolithic monuments in Western Europe; especially Gavrinis in Brittany, which has a similar preserved facing and large carved stones, Maeshowe in Orkney, with its large corbelled chamber, and Bryn Celli Ddu in Wales.

Watson Brake is an archaeological site in present-day Ouachita Parish, Louisiana, from the Archaic period. Dated to about 5400 years ago (approx. 3500 BCE), Watson Brake is considered the oldest earthwork mound complex in North America. It is older than the Ancient Egyptian pyramids or Britain’s Stonehenge. Its discovery and dating in a paper published in 1997 changed the ideas of American archaeologists about ancient cultures in the Southeastern United States and their ability to manage large, complex projects over centuries. The archeologists revised their date of the oldest earthwork construction by nearly 2000 years, as well as having to recognize that it was developed over centuries by a hunter-gatherer society, rather than by what was known to be more common of other, later mound sites: a more sedentary society dependent on maize cultivation and with a hierarchical, centralized polity.

The arrangement of human-made mounds at Watson Brake was constructed over centuries by members of a hunter-gatherer society. It is located near Watson Bayou in the floodplain of the Ouachita River, near present-day Monroe in northern Louisiana, United States. Watson Brake consists of an oval formation of eleven earthwork mounds from three to 25 feet (7.6 m) in height, connected by ridges to form an oval nearly 900 feet (270 m) across.

Denkmäler aus Ägypten und Äthiopien (literally "Monuments from Egypt and Ethiopia", where "Ethiopia" was then a synonym for Nubia) is a monumental work by Karl Richard Lepsius published in Prussia in 1849–1859. Like the French Description de l'Égypte, published forty years previously, the work is still regularly consulted by Egyptologists today.

It records the scientific documentation obtained by Lepsius's Prussian expedition to Egypt and Nubia from 1842–1845 in order to gather knowledge about the local monuments of ancient Egyptian civilization. This expedition was modelled after the earlier Napoléonic mission, and consisted of surveyors, draftsmen, and other specialists. The mission reached Giza in November 1842 and spent six months making some of the first scientific studies of the pyramids of Giza, Abusir, Saqqara, and Dahshur. They discovered 67 pyramids, recorded in the pioneering Lepsius list of pyramids, and more than 130 tombs. During the mission, the Prussian team collected around 15,000 objects and plaster casts, which today form the core of the collection of the Egyptian Museum of Berlin.
