Egyptology
Egyptology (from Egypt and Greek , -logia. ) is the study of ancient Egyptian history, language, literature, religion, architecture and art from the 5th millennium BC until the end of its native religious practices in the 4th century AD. A practitioner of the discipline is an "Egyptologist". In Europe, particularly on the Continent, Egyptology is primarily regarded as being a philological discipline, while in North America it is often regarded as a branch of archaeology.

History

First explorers
The first explorers were the ancient Egyptians themselves. Prompted by a dream he had, Thutmose IV restored the Sphinx and had the dream that inspired the restoration carved on the famous Dream Stele. Less than two centuries later, Prince Khaemweset, fourth son of Ramesses II, would gain fame for identifying and restoring historic buildings, tombs and temples, including pyramids.

Graeco-Roman Period
Some of the first historical accounts of Egypt were given by Herodotus, Strabo, Diodorus Siculus and the largely lost work of Manetho, an Egyptian priest, during the reign of Ptolemy I and Ptolemy II in the 3rd century BC. The Ptolemies were very interested in the work of the ancient Egyptians, and many of the Egyptian monuments, including the pyramids, were restored by them. The Ptolemies also built many new temples in the Egyptian style. The Romans also carried out restoration work in Egypt.

Middle Ages
Throughout the Middle Ages travelers on pilgrimages to the Holy Land would occasionally detour to visit sites in Egypt. Destinations would include Cairo and its environs, where the Holy Family was thought to have fled, and the great Pyramids, which were thought to be Joseph's Granaries, built by the Hebrew patriarch to store grain during the years of plenty. A number of their accounts (Itineraria) have survived and offer insights into conditions in their respective time periods.

Abdul Latif al-Baghdadi, a teacher at Cairo's Al-Azhar University in the 13th century, wrote detailed descriptions of ancient Egyptian monuments. Similarly, the 15th-century Egyptian historian al-Maqrizi wrote detailed accounts of Egyptian antiquities.

European explorers
European exploration and travel writings of ancient Egypt commenced in the 13th century, with only occasional detours into what could be considered a scientific approach, notably by Claude Sicard, Benoît de Maillet, Frederic Louis Norden and Richard Pococke. In the early 17th century, John Greaves measured the pyramids, having inspected the broken Obelisk of Domitian in Rome, then destined for the Earl of Arundel's collection in London. He went on to publish the illustrated Pyramidographia in 1646, while the Jesuit scientist-priest Athanasius Kircher was perhaps the first to hint at the phonetic importance of Egyptian hieroglyphs, demonstrating Coptic as a vestige of early Egyptian, for which he is considered a founder of Egyptology.

Modern Egyptology

Egyptology's modern history begins with the invasion of Egypt by Napoleon Bonaparte in the late 18th century. The Rosetta Stone was discovered in 1799. The study of many aspects of ancient Egypt became more scientifically oriented with the publication of Mémoires sur l'Égypte in 1800 and the more comprehensive Description de l'Egypte between 1809 and 1829. These recorded Egyptian flora, fauna, and history—making numerous ancient Egyptian source materials available to Europeans for the first time. The British captured Egypt from the French and gained the Rosetta Stone in 1801, the Greek script of which was translated by 1803. In 1822, the respective Egyptian hieroglyphs were transliterated by Jean-François Champollion, marking the beginning of modern Egyptology. With increasing knowledge of Egyptian writing, the study of ancient Egypt was able to proceed with greater academic rigour. Champollion, Thomas Young and Ippolito Rosellini were some of the first Egyptologists of wide acclaim. The German Karl Richard Lepsius was an early participant in the investigations of Egypt—mapping, excavating and recording several sites.

English Egyptologist Flinders Petrie (1853–1942) introduced archaeological techniques of field preservation, recording, and excavation to the field. Many highly educated amateurs also travelled to Egypt, including women such as Harriet Martineau and Florence Nightingale. Both of these left accounts of their travels, which revealed learned familiarity with all of the latest European Egyptology. Howard Carter's 1922 discovery of the tomb of 18th Dynasty King Tutankhamun brought a greater understanding of Egyptian relics and wide acclaim to the field.

In the modern era, the Ministry of State for Antiquities controls excavation permits for Egyptologists to conduct their work. The field can now use geophysical methods and other applications of modern sensing techniques.

In July 2019, ancient granite columns and a smaller Greek temple, treasure-laden ships, along with bronze coins from the reign of Ptolemy II, pottery dating back to the third and fourth centuries BC were found at the sunken city of Heracleion. The investigations were conducted by Egyptian and European divers led by underwater archaeologist Franck Goddio. They also uncovered the ruins of the city’s main temple off of Egypt's north coast.

Academic discipline

Egyptology was established as an academic discipline through the research of Emmanuel de Rougé in France, Samuel Birch in England, and Heinrich Brugsch in Germany.  In 1880, Flinders Petrie, another British Egyptologist, revolutionised the field of archaeology through controlled and scientifically recorded excavations. Petrie's work determined that Egyptian culture dated back as early as 4500 BC. The British Egypt Exploration Fund founded in 1882 and other Egyptologists promoted Petrie's methods.  Other scholars worked on producing a hieroglyphic dictionary, developing a Demotic lexicon, and establishing an outline of ancient Egyptian history.

In the United States, the founding of the Oriental Institute at the University of Chicago and the expedition of James Henry Breasted to Egypt and Nubia established Egyptology as a legitimate field of study. In 1924, Breasted also started the Epigraphic Survey to make and publish accurate copies of monuments.  In the late 19th and early 20th century, the Metropolitan Museum of Art; the University of Pennsylvania; the Museum of Fine Arts, Boston; the Brooklyn Institute of Fine Arts; and the Institute of Fine Arts, New York University also conducted 
excavations in Egypt, expanding American collections.

Some universities and colleges offer degrees in Egyptology. In the United States, these include the University of Chicago, Brown University, New York University, Yale University and Indiana University - Bloomington. There are also many programmes in the United Kingdom, including those at the University of Oxford, the University of Cambridge, Swansea University, the University of Liverpool, the University of Manchester, and the University of London. While Egyptology is widely studied in continental Europe, only Leiden University offers English taught degree programs in Egyptology.

Societies for Egyptology include:
 The Society for the Study of Ancient Egypt
 The Society for the Study of Ancient Egyptian Antiquities, Canada
 Sussex Egyptology Society Online
 Egypt Exploration Society

According to UCLA, the standard text that scholars referenced for studies of Egyptology was for three decades or more, the Lexikon der Ägyptologie (LÄ). The first volume published in 1975 (containing largely German-language articles, with a few in English and French).
