The Egyptian pyramids produce reflections that illuminated other places? Credit: Those who visited the Giza pyramids personally are always impressed by their size (particularly the pyramids of Khufu and Khafre).

It is difficult to capture in the camera the impact you feel in the presence of so many massive stone blocks, stacked so high.

As many readers will know, however, when they were first built, the pyramids would have looked even more impressive, as they had finished with polished limestone coating, smoothing the sides of the old landmarks and painting them white, allowing them to reflect intensely the light of the sun.

But could this reflective coating also have sent sunlight from the pyramids to other important locations? Donald E.

Jennings, a retired physicist at the Goddard Space Flight Center, noted that the high quality Tura limestone used for the outer shell of the pyramid could have been polished to the point of allowing specular reflection (strong specular reflections can still be seen in the polished granite pyramids of Amenemhet III and Khendjer), similar to those of a glass window, and wondered if the Egyptians used it with good results.

Reflections towards points on the horizon would be visible from great distances.

On a certain day and time when the Sun was properly situated, an observer stationed in a distant location would have seen a momentary glow as the suns reflection moved along the face of the pyramid.

The Egyptian pyramids produce reflections that illuminated other places? Pyramid of Amenemhat III (photo by Jon Bodsworth) Jennings was intrigued enough by the idea that he modeled specular reflections of the Khufu pyramid and derived the annual dates and times when they would be visible in important ancient sites of the Egyptian calendar, as well as on solar equinoxes, solstices and one-bedroom days.

Your investigation is documented in a new article on,? Specular Reflection from the Great Pyramid at Giza? (mean? Spectacular Reflection of the Great Pyramid at Giza ?) The locations Jennings included in his investigation included Heliopolis (the ?City of the Sun?, home to the Temple of Ra), the pyramid of Djedefre, and Memphis (the capital of the Ancient Kingdom in Egypt) south of Giza.

By modeling the trajectory of the Sun and how its light would have reflected ?The celebration of WePetrenPet, which at the time of construction of the pyramid occurred near the fourth quarter of spring, would have been marked by a specular scan of locations on the south horizon.

In the quarterly days of autumn and winter, of reflexes would have been directed to Heliopolis.

Imagine being in Heliopolis in early February 2560 BC, looking southwest across the Nile Valley.

The newly completed giant pyramid, called the ?Khufu horizon?, shines in white and dominates the horizon.

Suddenly, just before midday, the pyramid begins to lighten and soon shines like a second sun, imitating a sunset.

For that brief time the great pyramid controlled the Sun, sending a piece of it to its home, the temple of Ra...

is a clear demonstration of the connection between its king and the sun god.? Jennings article also calculates the times and places where the reflection of the sun was sent to the horizon, as well as observes that on the winter solstice,? Was the reflection of the sun on the southern face of the pyramid of Khufu at 39.8? , almost directly back in itself.

In this arrangement, the sun in a certain sense was? Seeing? your own reflection? He notes, however, that although this peculiar alignment is the result of the slope of 51.8? from the side of the pyramid, it is unlikely that it was an intentional effect.

In addition, overall Jennings recognizes that ?does not know any ancient records of these exhibitions? about which he is raising the hypothesis, and ?if the great pyramids have produced specular reflections it cannot be known for sure?, because without evidence from the archaeological record ?no can we be sure that the limestone coating has been polished for a mirrored finish?.

As he pointed out earlier, however, we know that the existing polished granite pyramids cast specular reflections, and it is believed that some pyramids/domes were coated with gold, which would have produced an intense reflection.

But, Jennings argues, ?given the central role of the Sun in its culture, it is likely that Egyptians would consider the solar specular effect on their architecture.

And perhaps the effect does not have to have even been planned in architecture ? its manifestation in the environment would still have been noticed and perhaps venerated:.
