Amun (also Amon, Ammon, Amen) is 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 Amaunet. With the 11th dynasty (c. 21st century BC), Amun rose to the position of patron deity of Thebes by replacing Montu. 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 or Amun-Re.
Amun-Ra retained chief importance in the Egyptian pantheon throughout the New Kingdom (with the exception of the "Atenist heresy" under Akhenaten). Amun-Ra in this period (16th to 11th centuries BC) held the position of transcendental, self-created creator deity "par excellence", he was the champion of the poor or troubled and central to personal piety. His position as King of Gods developed to the point of virtual monotheism where other gods became manifestations of him. With Osiris, Amun-Ra is the most widely recorded of the Egyptian gods.
As the chief deity of the Egyptian Empire, Amun-Ra also came to be worshipped outside Egypt, according to the testimony of ancient Greek historiographers in Libya and Nubia. As Zeus Ammon, he came to be identified with Zeus in Greece.
Amun and Amaunet are mentioned in the Old Egyptian Pyramid Texts. The name Amun meant something like "the hidden one" or "invisible". Amun rose to the position of tutelary deity of Thebes after the end of the First Intermediate Period, under the 11th dynasty. As the patron of Thebes, his spouse was Mut. In Thebes, Amun as father, Mut as mother and the Moon god Khonsu formed a divine family or "Theban Triad".
TEMPLE OF KARNAK
The history of Amun as the patron god of Thebes begins in the 20th century BC, with the construction of the Precinct of Amun-Re at Karnak under Senusret I. Major construction work in the Precinct of Amun-Re took place during the 18th dynasty when Thebes became the capital of the unified ancient Egypt. Construction of the Hypostyle Hall may have also begun during the 18th dynasty, though most building was undertaken under Seti I and Ramesses II. Merenptah commemorated his victories over the Sea Peoples on the walls of the Cachette Court, the start of the processional route to the Luxor Temple. This Great Inscription (which has now lost about a third of its content) shows the king's campaigns and eventual return with items of potential value and prisoners. Next to this inscription is the Victory Stela, which is largely a copy of the more famous Israel Stela found in the funerary complex of Merenptah on the west bank of the Nile in Thebes.
When the army of the founder of the Eighteenth dynasty expelled the Hyksos rulers from Egypt, the victor's city of origin, Thebes, became the most important city in Egypt, the capital of a new dynasty. The local patron deity of Thebes, Amun, therefore became nationally important. The pharaohs of that new dynasty attributed all their successful enterprises to Amun, and they lavished much of their wealth and captured spoil on the construction of temples dedicated to Amun.
