Karnak is an ancient Egyptian temple precinct located on the east bank of the Nile River in Thebes (modern-day Luxor). It covers more than 100 hectares, an area larger than some ancient cities. The Karnak Temple Complex, commonly known as Karnak which means "fortified village"), comprises a vast mix of decayed temples, chapels, pylons, and other buildings near Luxor, in Egypt. Construction at the complex began during the reign of Senusret I in the Middle Kingdom (around 2000–1700 BC) and continued into the Ptolemaic period (305–30 BC), although most of the extant buildings date from the New Kingdom. The area around Karnak was the ancient Egyptian Ipet-isut ("The Most Selected of Places") and the main place of worship of the Eighteenth Dynasty Theban Triad of Amun, Mut, and Khonsu (with the god Amun as its head). It is part of the monumental city of Thebes. The Karnak complex gives its name to the nearby, and partly surrounded, modern village of El-Karnak. This derelict place is still capable of overshadowing many wonders of the modern world and in its day must have been awe-inspiring. For the largely uneducated ancient Egyptian population, this could only have been the place of the gods. It is the largest religious building ever made, covering about 200 acres, and was a place of pilgrimage for nearly 2,000 years. Karnak would have made a great impression on ancient visitors, to say the least. “The pylons and great enclosure walls were painted white with the reliefs and inscriptions picked out in brilliant jewel-like colours, adding to their magnificence,” writes Egyptologist Heather Blyth in her book "Karnak: Evolution of a Temple" (Routledge, 2006). “Behind the high walls, glimpses of gold-topped obelisks which pierced the blue sky, shrines, smaller temples, columns and statues, worked with gold, electrum and precious stones such as lapis lazuli must have shimmered in the dusty golden heat.” Blyth notes that the earliest certain evidence of construction at Karnak dates to the reign of Wah-Ankh Intef II, an Egyptian ruler who lived more than 4,000 years ago. An “eight-sided” sandstone column of his bears the name of Amun-Ra and says “he [the king] made it as his monument for that god ...” The complex is a vast open site and includes the Karnak Open Air Museum, It consists of four main parts, of which only the largest is currently open to the general public. The term Karnak often is understood as being the Precinct of Amun-Re only, because this is the only part most visitors see. The three other parts, the Precinct of Mut, the Precinct of Montu, and the dismantled Temple of Amenhotep IV, are closed to the public. There also are a few smaller temples and sanctuaries connecting the Precinct of Mut, the Precinct of Amun-Re, and the Luxor Temple. The Precinct of Mut is very ancient, being dedicated to an Earth and creation deity, but not yet restored. The original temple was destroyed and partially restored by Hatshepsut, although another pharaoh built around it in order to change the focus or orientation of the sacred area. Many portions of it may have been carried away for use in other buildings. The key difference between Karnak and most of the other temples and sites in Egypt is the length of time over which it was developed and used. Construction of temples started in the Middle Kingdom and continued into Ptolemaic times. Approximately thirty pharaohs contributed to the buildings, enabling it to reach a size, complexity, and diversity not seen elsewhere. Few of the individual features of Karnak are unique, but the size and number of features are overwhelming. The deities represented range from some of the earliest worshiped to those worshiped much later in the history of the Ancient Egyptian culture. Although destroyed, it also contained an early temple built by Amenhotep IV (Akhenaten), the pharaoh who later would celebrate a near monotheistic religion he established that prompted him to move his court and religious center away from Thebes. It also contains evidence of adaptations, where the buildings of the ancient Egyptians were used by later cultures for their own religious purposes. One famous aspect of Karnak is the Great Hypostyle Hall in the Precinct of Amun-Re, a hall area of 50,000 sq ft (5,000 m2) with 134 massive columns arranged in 16 rows. One hundred and twenty-two of these columns are 10 metres (33 ft) tall, and the other 12 are 21 metres (69 ft) tall with a diameter of over 3 metres (9.8 ft). This would be an extremely time-consuming process and also would require great balance to get to such great heights. A common alternative theory regarding how they were moved is that large ramps were constructed of sand, mud, brick or stone and that the stones were then towed up the ramps. If stone had been used for the ramps, they would have been able to use much less material. The top of the ramps presumably would have employed either wooden tracks or cobblestones for towing the megaliths. There is an unfinished pillar in an out-of-the-way location that indicates how it would have been finished. Final carving was executed after the drums were put in place so that it was not damaged while being placed. Several experiments moving megaliths with ancient technology were made at other locations some of them are listed here. The history of the Karnak complex is largely the history of Thebes and its changing role in the culture. Religious centers varied by region, and when a new capital of the unified culture was established, the religious centers in that area gained prominence. The city of Thebes does not appear to have been of great significance before the Eleventh Dynasty and previous temple building there would have been relatively small, with shrines being dedicated to the early deities of Thebes, the Earth goddess Mut and Montu. Early building was destroyed by invaders. The earliest known artifact found in the area of the temple is a small, eight-sided column from the Eleventh Dynasty, which mentions Amun-Re. Amun (sometimes called Amen) was long the local tutelary deity of Thebes. He was identified with the ram and the goose. The Egyptian meaning of Amun is "hidden" or the "hidden god". Major construction work in the Precinct of Amun-Re took place during the Eighteenth Dynasty, when Thebes became the capital of the unified Ancient Egypt. Almost every pharaoh of that dynasty added something to the temple site. Thutmose I erected an enclosure wall connecting the Fourth and Fifth pylons, which comprise the earliest part of the temple still standing in situ. Hatshepsut had monuments constructed and also restored the original Precinct of Mut, that had been ravaged by the foreign rulers during the Hyksos occupation. She had twin obelisks, at the time the tallest in the world, erected at the entrance to the temple. One still stands, as the tallest surviving ancient obelisk on Earth; the other has broken in two and toppled. Another of her projects at the site, Karnak's Red Chapel or Chapel Rouge, was intended as a barque shrine and originally may have stood between her two obelisks. She later ordered the construction of two more obelisks to celebrate her sixteenth year as pharaoh; one of the obelisks broke during construction, and thus, a third was constructed to replace it. The broken obelisk was left at its quarrying site in Aswan, where it still remains. Known as the unfinished obelisk, it provides evidence of how obelisks were quarried. Construction of the Great Hypostyle Hall also may have begun during the Eighteenth Dynasty (although most new building was undertaken under Seti I and Ramesses II in the Nineteenth). Merneptah, also of the Nineteenth Dynasty, commemorated his victories over the Sea Peoples on the walls of the Cachette Court, the start of the processional route to the Luxor Temple. The last major change to the Precinct of Amun-Re's layout was the addition of the First Pylon and the massive enclosure walls that surround the whole precinct, both constructed by Nectanebo I of the Thirtieth Dynasty. In 323 AD, Roman emperor Constantine the Great recognised the Christian religion, and in 356 Constantius II ordered the closing of pagan temples throughout the Roman Empire, into which Egypt had been annexed in 30 BC. Karnak was by this time mostly abandoned, and Christian churches were founded among the ruins, the most famous example of this is the reuse of the Festival Hall of Thutmose III's central hall, where painted decorations of saints and Coptic inscriptions can still be seen. Thebes' exact placement was unknown in medieval Europe, though both Herodotus and Strabo give the exact location of Thebes and how long up the Nile one must travel to reach it. Maps of Egypt, based on the 2nd century Claudius Ptolemaeus' mammoth work Geographia, had been circulating in Europe since the late 14th century, all of them showing Thebes' (Diospolis) location. Despite this, several European authors of the 15th and 16th centuries who visited only Lower Egypt and published their travel accounts, such as Joos van Ghistele and André Thévet, put Thebes in or close to Memphis. The Karnak temple complex is first described by an unknown Venetian in 1589, although his account gives no name for the complex. This account, housed in the Biblioteca Nazionale Centrale di Firenze, is the first known European mention, since ancient Greek and Roman writers, about a whole range of monuments in Upper Egypt and Nubia, including Karnak, Luxor temple, the Colossi of Memnon, Esna, Edfu, Kom Ombo, Philae, and others. The first drawing of Karnak is found in Paul Lucas' travel account of 1704, (Voyage du Sieur Paul Lucas au Levant). It is rather inaccurate, and can be quite confusing to modern eyes. Lucas travelled in Egypt during 1699–1703. The drawing shows a mixture of the Precinct of Amun-Re and the Precinct of Montu, based on a complex confined by the three huge Ptolemaic gateways of Ptolemy III Euergetes / Ptolemy IV Philopator, and the massive 113 m long, 43 m high and 15 m thick, First Pylon of the Precinct of Amun-Re. The Egyptians believed that towards the end of annual agricultural cycle the gods and the earth became exhausted and required a fresh input of energy from the chaotic energy of the cosmos. To accomplish this magical regeneration the Opet festival was held yearly at Karnak and Luxor. It lasted for twenty-seven days and was also a celebration of the link between pharaoh and the god Amun. The procession began at Karnak and ended at Luxor Temple, one and a half miles (2.4 kilometres) to the south. The statue of the god Amun was bathed with holy water, dressed in fine linen, and adorned in gold and silver jewellery. The priests then placed the god in a shrine and onto the ceremonial barque supported by poles for carrying. Pharaoh emerged from the temple, his priests carrying the barque on their shoulders, and together they moved into the crowded streets. A troop of Nubian soldiers serving as guards beat their drums, and musicians accompanied the priests in song as incense filled the air. At Luxor, (right) Pharaoh and his priests entered the temple and ceremonies were performed to regenerate Amun, recreate the cosmos and transfer Amun’s power to Pharaoh. When he finally emerged from the temple sanctuary, the vast crowds cheered him and celebrated the guaranteed fertility of the earth and the expectation of abundant harvests. During the festival the people were given over 11000 loaves of bread and more than 385 jars of beer, and some were allowed into the temple to ask questions of the god. The priests spoke the answers through a concealed window high up in the wall, or from inside hollow statues.
