Coptic language in the context of Cusae

Heracleion (Ancient Greek: Ἡράκλειον Hērákleion), also known as Thonis (Ancient Greek: Θῶνις Thônis; from the Ancient Egyptian: Tȝ-ḥn.t; Coptic: Ⲧϩⲱⲛⲓ Thōni) and sometimes called Thonis-Heracleion, was an ancient Egyptian port city located near the Canopic Mouth of the Nile, about 32 km (20 mi) northeast of Alexandria on the Mediterranean Sea. It became inundated; its remains are located in Abu Qir Bay, which in 2022 was 7 km (4.3 mi) off the coast and approximately 5.8 m (19 ft) underwater, and near Abukir. The sanctuary of Neith of Sais was located in Thonis. A stele found on the site indicates that late in its history the city was known by both its Egyptian and Greek names.

The legendary beginnings of Thonis go back to as early as the 12th century BC, and it is mentioned by ancient Greek historians. Its importance grew particularly during the waning days of the pharaohs.

Naucratis or Naukratis (Ancient Greek: Ναύκρατις, "Naval Command"; Egyptian: njwt-kꜣrṯ, nskꜣrṯ, pr-mryt, Coptic: Ⲡⲓⲉⲙⲣⲱ Piemro) was a city and trading-post in ancient Egypt, located on the Canopic (western-most) branch of the Nile river, south-east of the Mediterranean sea and the city of Alexandria. Naucratis was the first and, for much of its early history, the only permanent Greek settlement in Egypt, serving as a symbiotic nexus for the interchange of Greek and Egyptian art and culture.

The modern villages of Kom Gi'eif, el-Nibeira and el-Niqrash cover the archaeological site, which is of great importance. It is the source of numerous art objects in many of the world's museums, as well as pottery inscribed with some of the earliest known examples of Greek writing.

The Islamization of Egypt occurred after the seventh-century Muslim conquest, in which the Islamic Rashidun Caliphate seized control of Egypt from the Christian dominated Byzantine Empire. Egypt and other conquered territories in Africa gradually underwent a large-scale conversion from Christianity to Islam, motivated in part by a jizya tax for those who refused to convert. Islam became the faith of the majority of the population at some point between the 13th and 14th centuries, and Arabic became the main language, replacing Coptic and Greek, which had previously served as the vernacular and governmental languages, respectively.

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.

Memphis (Arabic: مَنْف, romanized: Manf, pronounced [mænf]; Bohairic Coptic: ⲙⲉⲙϥⲓ; Greek: Μέμφις), or Men-nefer, was the ancient capital of Inebu-hedj, the first nome of Lower Egypt that was known as mḥw ("North"). Its ruins are located in the vicinity of the present-day village of Mit Rahina (Arabic: ميت رهينة), in Badrashin markaz (county), Giza Governorate, Egypt.

Along with the pyramid fields that stretch across a desert plateau for more than 30 kilometres (19 mi) on its west, including the famous Pyramids of Giza, Memphis and its necropolis have been listed as a World Heritage Site. The site is open to the public as an open-air museum.

Abu Rawash (also spelled Abu Roach, Abu Roash; Arabic: ابو رواش  Egyptian Arabic pronunciation: [ˈæbu ɾæˈwæːʃ], Coptic: ⲁⲃⲣⲱⲟⲩϣⲓ abrowshi, Coptic pronunciation: [ɑbˈroːwʃi], "flesh of sensual pleasures"), 8 kilometres (5.0 mi) north of Giza, is the site of Egypt's most northerly pyramid, also known as the lost pyramid – the mostly ruined Pyramid of Djedefre, the son and successor of Khufu. Originally, it was thought that this pyramid had never been completed, but the current archaeological consensus is that not only was it completed, but that it was built about the same size as the Pyramid of Menkaure – the third largest of the Giza pyramids. It's believed that the destruction of the pyramid started at the end of the New Kingdom at the latest, and was particularly intense during the Roman and early Christian eras when a Coptic monastery was built in nearby Wadi Karin. It has been proven, moreover, that at the end of the nineteenth century, stone was still being hauled away at the rate of three hundred camel loads a day.

The Kingdom of Kush (/kʊʃ, kʌʃ/; Egyptian: 𓎡𓄿𓈙𓈉 kꜣš, Assyrian: Kûsi, in LXX Χους or Αἰθιοπία; Coptic: ⲉϭⲱϣ Ecōš; Hebrew: כּוּשׁ Kūš), also known as the Kushite Empire, or simply Kush, was an ancient kingdom in Nubia, centered along the Nile Valley in what is now northern Sudan and southern Egypt.

The region of Nubia was an early cradle of civilization, producing several complex societies that engaged in trade and industry. The city-state of Kerma emerged as the dominant political force between 2450 and 1450 BC, controlling the Nile Valley between the first and fourth cataracts, an area as large as Egypt. The Egyptians were the first to identify Kerma as "Kush" probably from the indigenous ethnonym "Kasu", over the next several centuries the two civilizations engaged in intermittent warfare, trade, and cultural exchange.

Late antique literature is literature that was composed during the period of late antiquity, a period of time that spans from the third to seventh centuries AD. This literature was written in many languages including Greek, Latin, Coptic, Syriac, Armenian, Georgian, Pahlavi, Arabic, and more.

Despite twentieth-century prejudices about the era as one of a period of decline, literature in late antiquity was highly productive and innovative and brought about new genres of texts, new avenues for literary productions, new textual functions, and new reading practices. The most important force causing change in literature during this time was the political and cultural rise of Christianity, which remade older genres in the classical canon and interweaved them with a new canon of scriptural texts and liturgy. Furthermore, the end of Late antiquity saw the last major representatives of Greek and Latin poetry, whereas poetry in other languages (like Syriac poetry) began to flourish.

Abu Qir (Arabic: ابو قير, Abu Qīr, [æbuˈ] or [æbo ʔiːɾ], Coptic: ⲁⲡⲁⲕⲩⲣⲓ Apakyri), formerly also spelled Abukir or Aboukir, is a town on the Mediterranean coast of Egypt, near the ruins of ancient Canopus and 23 kilometers (14 mi) northeast of Alexandria by rail. It is located on Abu Qir Peninsula, with Abu Qir Bay to the east.

Sais (Ancient Greek: Σάϊς, Coptic: Ⲥⲁⲓ) was an ancient Egyptian city in the Western Nile Delta on the Canopic branch of the Nile, known by the ancient Egyptians as Sꜣw. It was the provincial capital of Sap-Meh, the fifth nome of Lower Egypt and became the seat of power during the Twenty-fourth Dynasty of Egypt (c. 732–720 BC) and the Saite Twenty-sixth Dynasty of Egypt (664–525 BC) during the Late Period. On its ruins today stands the town of Sa el-Hagar (Egyptian Arabic: صا الحجر) or Sa El Hajar.

Sophia (Koine Greek: Σοφíα "Wisdom", Coptic: ⲧⲥⲟⲫⲓⲁ "the Sophia") is a figure, along with Knowledge (γνῶσις gnosis, Coptic: ⲧⲥⲱⲟⲩⲛ tsōwn), among many of the early Christian knowledge theologies grouped by the heresiologist Irenaeus as gnostikoi (γνωστικοί), "knowing". Gnosticism is a 17th-century term expanding the definition of Irenaeus' groups to include other syncretic faiths and the Greco-Roman mysteries.

In Gnosticism, Sophia is a feminine figure, analogous to the human soul but also simultaneously one of the feminine aspects of God. Gnostics held that she was the syzygy, or female twin, of Jesus, i.e. the Bride of Christ, and the Holy Spirit of the Trinity. She is occasionally referred to by the term Achamōth (Ἀχαμώθ, Hebrew: חכמה chokmah) and as Prunikos (Προύνικος). In the Nag Hammadi texts, Sophia is the highest aeon or anthropic emanation of the godhead.

Cyril of Alexandria (Ancient Greek: Κύριλλος Ἀλεξανδρείας; Coptic: Ⲡⲁⲡⲁ Ⲕⲩⲣⲓⲗⲗⲟⲩ ⲁ̅ or Coptic: Ⲡⲓⲁⲅⲓⲟⲥ Ⲁⲃⲃⲁ Ⲕⲩⲣⲓⲗⲗⲟⲥ ⲡⲓⲥⲧⲩⲗⲗⲟⲥ ⲛ̀ⲧⲉ ⲡⲓⲛⲁϩϯ or ⲡⲓ̀ⲁⲅⲓⲟⲥ Ⲕⲓⲣⲓⲗⲗⲟⲥ; c. 376–444) was the Patriarch of Alexandria from 412 to 444. He was enthroned when the city was at the height of its influence and power within the Roman Empire. Cyril wrote extensively and was a major player in the Christological controversies of the late 4th and 5th centuries. He was a central figure in the Council of Ephesus in 431, which led to the deposition of Nestorius as Patriarch of Constantinople.

Cyril is counted among the Church Fathers and also as a Doctor of the Church, and his reputation within the Christian world has resulted in his titles Pillar of Faith and Seal of all the Fathers. The Nestorian bishops at their synod at the Council of Ephesus declared him a heretic, labelling him as a "monster, born and educated for the destruction of the church".

The Coptic Orthodox Church (Coptic: Ϯⲉⲕ̀ⲕⲗⲏⲥⲓⲁ ⲛ̀ⲣⲉⲙⲛ̀ⲭⲏⲙⲓ ⲛ̀ⲟⲣⲑⲟⲇⲟⲝⲟⲥ, romanized: Ti-eklisia en-remenkimi en-orthodhoxos, lit. 'the Egyptian Orthodox Church'; Arabic: الكنيسة القبطية الأرثوذكسية, romanized: al-Kanīsa al-Qibṭiyya al-ʾUrthūdhuksiyya), also known as the Coptic Orthodox Patriarchate of Alexandria, is an Oriental Orthodox Christian church based in Egypt. The head of the church and the See of Alexandria is the pope of Alexandria on the Holy Apostolic See of Saint Mark, who also carries the title of Father of fathers, Shepherd of shepherds, Ecumenical Judge and the 13th among the Apostles.

The See of Alexandria is titular. The Coptic pope presides from Saint Mark's Coptic Orthodox Cathedral in the Abbassia District in Cairo. The church follows the Coptic Rite for its liturgy, prayer and devotional patrimony. Adherents of the Coptic Orthodox Church make up Egypt's largest and most significant minority population, and the largest population of Christians in the Middle East and North Africa (MENA). They make up the largest share of the approximately 10 million Christians in Egypt.

Copts (Coptic: ⲚⲓⲢⲉⲙ̀ⲛⲭⲏⲙⲓ ̀ⲛ̀Ⲭⲣⲏⲥⲧⲓ̀ⲁⲛⲟⲥ, romanized: NiRemenkēmi enKhristianos; Arabic: أقباط, romanized: aqbāṭ) are a Christian ethnoreligious group native to Northeast Africa who have primarily inhabited the area of modern Egypt since antiquity. They are, like the broader Egyptian population, descended from the ancient Egyptians. Copts predominantly follow the Coptic Orthodox Church, the Alexandrian Greek Orthodox Church and the Coptic Catholic Church. They are the largest Christian population in Egypt and the Middle East, as well as in Sudan and Libya. Copts account for roughly 5 to 15 percent of the population of Egypt.

Originally referring to all Egyptians, the term Copt became synonymous with native Christians in light of Egypt's Islamization and Arabization after the Muslim conquest of Egypt in 639–646 AD. Copts have historically spoken the Coptic language, a direct descendant of the Demotic Egyptian that was spoken in late antiquity.

Egyptian Arabic, locally known as Colloquial Egyptian, or simply as Masri, is the most widely spoken vernacular Arabic variety in Egypt. It is part of the Afro-Asiatic language family, and originated in the Nile Delta in Lower Egypt. The estimated 111 million Egyptians speak a continuum of dialects, among which Cairene is the most prominent. It is also understood across most of the Arabic-speaking countries due to broad Egyptian influence in the region, including through Egyptian cinema and Egyptian music. These factors help make it the most widely spoken and by far the most widely studied variety of Arabic.

While it is primarily a spoken language, the written form is used in novels, plays and poems (vernacular literature), as well as in comics, advertising, some newspapers and transcriptions of popular songs. In most other written media and in radio and television news reporting, literary Arabic is used. Literary Arabic is a standardized language based on the language of the Qur'an, i.e. Classical Arabic. The Egyptian vernacular is almost universally written in the Arabic alphabet for local consumption, although it is commonly transcribed into Latin letters or in the International Phonetic Alphabet in linguistics text and textbooks aimed at teaching non-native learners. Egyptian Arabic's phonetics, grammatical structure, and vocabulary are influenced by the Coptic language; its rich vocabulary is also influenced by Turkish and by European languages such as French, Italian, Greek, and English.

As used for Egyptology, transliteration of Ancient Egyptian is the process of converting (or mapping) texts written as Egyptian language symbols to alphabetic symbols representing uniliteral hieroglyphs or their hieratic and demotic counterparts. This process facilitates the publication of texts where the inclusion of photographs or drawings of an actual Egyptian document is impractical.

Transliteration is not the same as transcription. Transliteration is the representation of written symbols in a consistent way in a different writing system, while transcription indicates the pronunciation of a text. For the case of Ancient Egyptian, precise details of the phonology are not known completely. Transcription systems for Ancient Egyptian do exist, but they rely on linguistic reconstruction (depending on evidence from the Coptic language and other details) and are thus theoretical in nature. Egyptologists rely on transliteration in scientific publications. Egyptologists also call the process of converting hieratic texts to hieroglyphic text as "transcription."

The writing systems used in ancient Egypt were deciphered in the early nineteenth century through the work of several European scholars, especially Jean-François Champollion and Thomas Young. Ancient Egyptian forms of writing, which included the hieroglyphic, hieratic and demotic scripts, ceased to be understood in the fourth and fifth centuries AD, as the Coptic alphabet was increasingly used in their place. Later generations' knowledge of the older scripts was based on the work of Greek and Roman authors whose understanding was faulty. It was thus widely believed that Egyptian scripts were exclusively ideographic, representing ideas rather than sounds. Some attempts at decipherment by Islamic and European scholars in the Middle Ages and early modern times acknowledged the script might have a phonetic component, but perception of hieroglyphs as purely ideographic hampered efforts to understand them as late as the eighteenth century.

The Rosetta Stone, discovered in 1799 by members of Napoleon Bonaparte's campaign in Egypt, bore a parallel text in hieroglyphic, demotic and Greek. It was hoped that the Egyptian text could be deciphered through its Greek translation, especially in combination with the evidence from the Coptic language, the last stage of the Egyptian language. Doing so proved difficult, despite halting progress made by Antoine-Isaac Silvestre de Sacy and Johan David Åkerblad. Thomas Young, building on their work, observed that demotic characters were derived from hieroglyphs and identified several of the phonetic signs in demotic. He also identified the meaning of many hieroglyphs, including phonetic glyphs in a cartouche containing the name of an Egyptian king of foreign origin, Ptolemy V. He was convinced, however, that phonetic hieroglyphs were used only in writing non-Egyptian words. In the early 1820s Champollion compared Ptolemy's cartouche with others and realised the hieroglyphic script was a mixture of phonetic and ideographic elements. His claims were initially met with scepticism and with accusations that he had taken ideas from Young without giving credit, but they gradually gained acceptance. Champollion went on to roughly identify the meanings of most phonetic hieroglyphs and establish much of the grammar and vocabulary of ancient Egyptian. Young, meanwhile, largely deciphered demotic using the Rosetta Stone in combination with other Greek and demotic parallel texts.
