Thebes, Egypt in the context of "Egyptian calendar"

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 Middle Kingdom of Egypt (also known as The Period of Reunification) is the period in the history of ancient Egypt following a period of political division known as the First Intermediate Period. The Middle Kingdom lasted from approximately 2040 to 1782 BC, stretching from the reunification of Egypt under the reign of Mentuhotep II in the Eleventh Dynasty to the end of the Twelfth Dynasty. The kings of the Eleventh Dynasty ruled from Thebes and the kings of the Twelfth Dynasty ruled from el-Lisht.

The concept of the Middle Kingdom as one of three golden ages was coined in 1845 by German Egyptologist Baron von Bunsen, and its definition evolved significantly throughout the 19th and 20th centuries. Some scholars also include the Thirteenth Dynasty of Egypt wholly into this period, in which case the Middle Kingdom would end around 1650 BC, while others only include it until Merneferre Ay around 1700 BC, last king of this dynasty to be attested in both Upper and Lower Egypt. During the Middle Kingdom period, Osiris became the most important deity in popular religion. The Middle Kingdom was followed by the Second Intermediate Period of Egypt, another period of division that involved foreign rule of Lower Egypt by the Hyksos of West Asia.

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.

Menmaatre Ramesses XI (also written Ramses and Rameses) reigned from 1107 BC to somewhere between 1078 BC and 1068 BC and is generally considered the tenth and final pharaoh of the Twentieth Dynasty of Egypt and as such, the last king of the New Kingdom period. He ruled Egypt for at least 29 years although some Egyptologists think he could have ruled for as long as 30. The latter figure would be up to 2 years beyond this king's highest known date of Year 10 of the wḥm-mswt ("Renaissance") era or Year 28 of his reign. One scholar, Ad Thijs, has suggested that Ramesses XI could even have reigned as long as 33 years.

It is believed that Ramesses ruled into his Year 29 since a graffito records that the general and High Priest of Amun Piankh returned to Thebes from Nubia on III Shemu day 23—or just 3 days into what would have been the start of Ramesses XI's 29th regnal year. Piankh is known to have campaigned in Nubia during Year 28 of Ramesses XI's reign (or Year 10 of the wḥm-mswt) and would have returned home to Egypt in the following year.

The First Intermediate Period, described as a 'dark period' in ancient Egyptian history, spanned approximately 125 years, c. 2181 – c. 2055 BC, after the end of the Old Kingdom. It comprises the Seventh (although this is mostly considered spurious by Egyptologists), Eighth, Ninth, Tenth, and part of the Eleventh Dynasties. The concept of a "First Intermediate Period" was coined in 1926 by Egyptologists Georg Steindorff and Henri Frankfort.

Very little monumental evidence survives from this period, especially from the beginning of the era. The First Intermediate Period was a dynamic time in which rule of Egypt was roughly equally divided between two competing power bases. One of the bases was at Heracleopolis in Lower Egypt, a city just south of the Faiyum region, and the other was at Thebes, in Upper Egypt. It is believed that during that time, temples were pillaged and violated, artwork was vandalized, and the statues of kings were broken or destroyed as a result of the postulated political chaos. The two kingdoms would eventually come into conflict, which would lead to the conquest of the north by the Theban kings and to the reunification of Egypt under a single ruler, Mentuhotep II, during the second part of the Eleventh Dynasty. This event marked the beginning of the Middle Kingdom of Egypt.

Thutmose I (sometimes read as Thutmosis or Tuthmosis I, Thothmes in older history works in Latinized Greek; meaning "Thoth is born") was the third pharaoh of the 18th Dynasty of Egypt. He received the throne after the death of the previous king, Amenhotep I. During his reign, he campaigned deep into the Levant and Nubia, pushing the borders of Egypt farther than ever before in each region. He also built many temples in Egypt, and a tomb for himself in the Valley of the Kings; he is the first king confirmed to have done this (though Amenhotep I may have preceded him).

Thutmose I's reign is generally dated to 1506–1493 BC, but a minority of scholars—who think that astrological observations used to calculate the timeline of ancient Egyptian records, and thus the reign of Thutmose I, were taken from the city of Memphis rather than from Thebes—would date his reign to 1526–1513 BC. He was succeeded by his son Thutmose II, who in turn was succeeded by Thutmose II's sister, Hatshepsut.

Astronomical ceiling decoration in its earliest form can be traced to the tomb of Senenmut (Theban tomb no. 353), located at the site of Deir el-Bahri, discovered in Thebes, Upper Egypt. The tomb and the ceiling decorations date back to the XVIII Dynasty of ancient Egypt (circa 1479–1458 BCE). It is closed to the public.

Amun was a major ancient Egyptian deity who appears as a member of the Hermopolitan Ogdoad. Amun was attested from the Old Kingdom together with his wife Amunet. His oracle in Siwa Oasis, located in Western Egypt near the Libyan Desert, remained the only oracle of Amun throughout. With the 11th Dynasty (c. 21st century BC), Amun rose to the position of patron deity of Thebes by replacing Montu.

Initially possibly one of eight deities in the Hermapolite creation myth, his worship expanded. After the rebellion of Thebes against the Hyksos and with the rule of Ahmose I (16th century BC), Amun acquired national importance, expressed in his fusion with the Sun god, Ra, as Amun-Ra (alternatively spelled Amon-Ra or Amun-Re). On his own, he was also thought to be the king of the gods.
