Abu Simbel temples
´
The Abu Simbel temples are two massive rock temples in Abu Simbel (أبو سمبل in Arabic) in Nubia, southern Egypt. They are situated on the western bank of Lake Nasser, about 230 km southwest of Aswan (about 300 km by road). The complex is part of the UNESCO World Heritage Site known as the "Nubian Monuments," which run from Abu Simbel downriver to Philae (near Aswan).
The twin temples were originally carved out of the mountainside during the reign of Pharaoh Ramesses II in the 13th century BCE, as a lasting monument to himself and his queen Nefertari, to commemorate his alleged victory at the Battle of Kadesh. However, the complex was relocated in its entirety in 1968, on an artificial hill made from a domed structure, high above the Aswan High Dam reservoir.
The relocation of the temples was necessary to avoid their being submerged during the creation of Lake Nasser, the massive artificial water reservoir formed after the building of the Aswan High Dam on the Nile River. Abu Simbel remains one of Egypt´s top tourist attractions.
Solar phenomena
It is believed that the axis of the temple was positioned by the ancient Egyptian architects in such a way that on October 22 and February 22, the rays of the sun would penetrate the sanctuary and illuminate the sculptures on the back wall, except for the statue of Ptah, the god connected with the Underworld, who always remained in the dark. People gather at Abu Simbel to witness this remarkable sight, on October 21st and February 21st
These dates are allegedly the king´s birthday and coronation day respectively, but there is no evidence to support this, though it is quite logical to assume that these dates had some relation to a great event, such as the jubilee celebrating the thirtieth anniversary of the pharaoh´s rule.
In fact, according to calculations made on the basis of the heliacal rising of the star Sirius (Sothis) and inscriptions found by archaeologists, this date must have been October 22. This image of the king was enhanced and revitalized by the energy of the solar star, and the deified Ramesses the Great could take his place next to Amun Ra and Ra-Horakhty.
Due to the displacement of the temple and/or the accumulated drift of the Tropic of Cancer during the past 3,280 years, it is widely believed that each of these two events has moved one day closer to the Solstice, so they would be occurring on October 22 and February 20 (60 days before and 60 days after the Solstice, respectively).
The NOAA Solar Position Calculator may be used to verify the declination of the Sun for any location on Earth, at any particular date and time. For the latitude of Abu Simbel 22°20′13″N 31°37′32″E, the calculator will yield values close to −11° for both Oct 22 and Feb 20.
