The Great Pyramid's Latitude

Spend long enough on the Internet and you will likely be met with a post informing you that the speed of light is 299,792,458 meters per second, and the latitude of the Great Pyramid of Giza is 29.9792458°N, before inviting you to assess whether this is a coincidence or not.

But is it true, and if so, is it a coincidence?

The answer to the first question is yes. Light travels at 299,792,458 meters per second in a vacuum, the absolute speed limit of the universe. The latitude of the Great Pyramid of Giza is indeed 29.9792458 N – but so are a whole bunch of other places at the same latitude.  READ MORE...

Great Pyramid of Giza

The Great Pyramid of Giza is the last remaining artefact in the seven wonders of the ancient world, a fascinating emblem of the ancient civilization that once ruled over Egypt. Along with the surrounding pyramids in the Giza complex, the Great Pyramid is remarkably well preserved, and has become a UNESCO World Heritage site which is under extensive protection. 

Built over 4,000 years ago, it is the largest pyramid in the world, and remained the tallest structure made by human hands for over 3,000 years, until the Eiffel Tower was constructed in Paris in 1889.

How, exactly, such a colossal structure was built has been a subject of fascination for centuries. The purpose of the Great Pyramid of Giza has also been a source of extensive study and research. Below we outline some of the most widely accepted purposes of the Great Pyramid that attracts millions of tourists every year.

Historians believe the primary role of the Great Pyramid of Giza was to act as a tomb for the great Egyptian King Khufu. Egyptians believed that their pharaohs would go on to become gods in the afterlife, but in order to prepare for a safe transition into the next world, they had to have the right burial chamber. 

King Khufu spent 27 years planning the construction of his pyramid with his cousin and vizier, the architect Hemiunu.

In its day it was the most impressive structure in the world, unlike anything anyone had seen, and its sheer scale and ingenuity seemed to represent the almighty power of the man who once ruled over the ancient kingdom, although it was more likely a demonstration of his kingdom’s wealth, which waned in subsequent generations. 

When Khufu died, his sarcophagus was placed inside the king’s chamber, deep inside the pyramid, although his remains were never found. However, his pyramid was surrounded by several satellite pyramids built for his wife and family.              TO READ MORE...

A Branch of the Nile Reveals...

A 4,500-year-old architectural marvel that still baffles scientists

Researchers have uncovered a now-dried-up branch of the Nile that came right up to the great pyramid complex of Giza about 4,500 years ago.

Awesome in size, with perfect geometry, and adorned with intricate decorations, the pyramids at Giza, on the outskirts of modern Cairo, served to demonstrate the power of the pharaohs in Egypt's golden ageResearchers have uncovered a now-dried-up branch of the Nile that came right up to the great pyramid complex of Giza about 4,500 years ago.

The findings, published in the Proceedings of the National Academy of Sciences on Monday, explain how ancient Egyptians were able to haul millions of the tons-heavy building blocks to the site of the iconic pyramids over four miles of what is now a desert landscape.

"It was impossible to build the pyramids here without this branch of the Nile," study author and geographer Hader Sheesh said, per The New York Times.       READ MORE...

Stashed Inside the Pyramids

Egyptian pyramids? (Image credit: Ratnakorn Piyasirisorost via Getty Images)

When British archaeologist Howard Carter cracked open King Tutankhamun's tomb in 1922, he reported seeing "wonderful things." Tut's tomb was filled with extraordinary treasures, including the golden death mask of Tutankhamun, a golden throne and even gold sandals. But did all royal tombs in ancient Egypt have such plush grave goods?


The answer is no. While the Great Pyramid of Giza and other ancient Egyptian pyramids are incredible monuments, the burial goods inside them were likely relatively modest compared with those buried in the tombs of later pharaohs, such as Tutankhamun.


"The burials in the biggest pyramids might have looked quite simple in comparison to Tutankhamun," Wolfram Grajetzki, an honorary senior research fellow at University College London in the U.K. who has studied and written extensively about ancient Egyptian burial customs and burial goods, told Live Science in an email.

Pyramids were used as Egyptian pharaohs' tombs from the time of Djoser (reign circa 2630 B.C. to 2611 B.C.) to Ahmose I (reign circa 1550 B.C. to 1525 B.C.). Most of these pyramids were plundered centuries ago, but a few royal tombs have remained relatively intact and provide clues about their treasures, Grajetzki said.


For instance, Princess Neferuptah (who lived around 1800 B.C.) was buried in a pyramid at the site of Hawara, around 60 miles (100 kilometers) south of Cairo. Her burial chamber was excavated in 1956 and "contained pottery, a set of coffins, some gilded personal adornments and a set of royal insignia that identify her with the Underworld god Osiris," Grajetzki said.


King Hor (who lived around 1750 B.C.) was buried with a similar set of objects, although he wasn't buried in a pyramid, Grajetzki said. "The body of [Hor] was wrapped in linen, the entrails placed into special containers, called canopic jars," Grajetzki said. "His face was covered with a mummy mask."  READ MORE...

The Pyramid Builders

We know it as the Great Pyramid. To the Ancient Egyptians it was the Akhet Khufu or Horizon of Khufu, named after the 4th Dynasty king who reigned from roughly 2633 BC to 2605 BC. By any measure, the pyramid that served as his tomb was a staggering accomplishment. Its four sides were each approximately 230m long, while the edifice incorporated some 2.3 million blocks and originally stood almost 150m high. Within lay an intricate network of chambers and passages, which showcase the skill of Egyptian masons. 

Despite the monument’s impressive statistics, though, there is one thing it is notably short of: text. Unlike some later pyramids, and the famous tombs crowding the Valley of the Kings, the interior of the Great Pyramid is not lavishly adorned with hieroglyphics. Instead, just a few graffiti naming work gangs were daubed in suitably discreet spots. Until recently, these sparse words provided the only contemporary textual glimpse of construction operations.

A decade ago, hoping to secure an eye-witness account of work on the Great Pyramid would have seemed like archaeological wishful thinking of the highest order. But then, in 2013, fragments of the earliest papyri documents ever found were recovered by an archaeological team led by Pierre Tallet, Professor of Egyptology at the University of Paris-Sorbonne. 

It speaks volumes about the scale of Khufu’s grand design that these texts, which were compiled by individuals involved with construction operations, were not found within the pyramid or even at Giza. Instead, they were recovered more than 130km away, in Egypt’s Eastern Desert near the Red Sea shore. The papyri comprise logbooks and other bureaucratic records that detail the activities of teams engaged on Khufu’s mortuary complex. 

Some of these accounts overlap in a remarkable fashion with the results of archaeological work led by Mark Lehner, President of AERA (Ancient Egypt Research Associates), at Giza. Now these two archaeologists have collaborated on a book shedding new light on one of the most renowned archaeological monuments in the world (see ‘Further reading’).  TO READ THE ENTIRE ARTICLE, CLICK HERE...

Pyramids, Pharaohs, and Secrets

Egyptian pyramids are ancient pyramid-shaped stone constructions located in Egypt. 

The number of objects identified as Egyptian pyramids is about 100. Most of the pyramids were built as tombs for the pharaohs of the ancient and middle kingdoms. The oldest is the Pyramid of Djoser, created by the architect Imhotep between 2667-2488 BC.

What are the facts about pyramids?
The most incredible Pyramid in the Giza complex is 147 meters high, with a base side of 230 meters, and took between 20 and 30 years to build. It is located about 25 kilometers southwest of Cairo, Egypt’s capital.

The Great Pyramid, also known as the Pyramid of Khufu, has 2.6 million cubic meters and is greater than the two Giza colossi, the pyramids of Menkaure and Khafre. All of the pyramids are said to have been coated with gleaming limestone at one point, but this has since been removed and reused in various construction projects throughout the millennia.

Each Pyramid at Giza is part of a larger complex that includes a tomb temple and a network of interconnected pathways. The monuments are essentially the last resting sites of Egypt’s famous pharaohs.  READ MORE...

Pyramids Not Created by Aliens

Because I once made the mistake of dabbling in Egyptology, some ‘friend’ will schwack me every other week with a meme, cartoon or article about people who still believe the pyramids were built by aliens. I have longed for a handy single volume to present to these loons, full of unarguable evidence putting this business past dispute – and Pierre Tallet and Mark Lehner have provided it.

In 2013 excavators in Egypt’s Eastern Desert on the Gulf of Suez uncovered the world’s most ancient harbour installation at Wadi el-Jarf. Here they unearthed a cache containing the oldest extant inscribed papyri (c.2607-5 BCE). And in that they found ‘unique and unprecedented testimony relating to one of the world’s most famous monuments’ which has inspired and perplexed visitors for almost five millennia: the Great Pyramid of Giza.

Little green men or Atlantean speculation is both a failure and an overuse of the imagination. But the pyramids, of course, are mind-boggling. For the Great Pyramid, King Khufu’s quarrymen hand-sculpted more than six hectares of rock to level the plateau and form a basic foundation, to legendary degrees of accuracy with regard to both the Earth and heavens. The block-hauling ramps alone are thought to have contained as much as 400,000 cubic metres of sand and rock – and perhaps only reached a fifth of the way up the edifice. The masons dressed precisely ‘67,127 square metres of the outer surface of the pyramid casing with copper chisels the width of an index finger’. The outer surface!

A ‘human disturbance on a geological scale’, the funerary complex of the Great Pyramid was so large that it incorporated other pyramids. The building site also contained an entire administrative city – ‘a kind of Old Kingdom Egyptian equivalent of Versailles’ – complete with an artificial inland port to take hydraulic advantage of the Nile flood.

In this book, handwritten scribal records – the ‘oldest known explicitly dated Egyptian documents’ – pick up the story of the middle-ranking inspector Merer and his 40-man naval gang. Merer was the captain of ‘Team Great’, an elite, adaptable outfit that transported the ‘grunt’ labour force and maintained the waterways around Giza, ferried limestone blocks up and down the Nile, provisioned and managed stores at the plateau and undertook expeditions to Sinai and Punt – lands, if not of milk and honey, of turquoise, myrrh and much needed copper for stone-working tools. ‘The builders of the gigantic pyramids of the 4th Dynasty must have amassed more copper... than was being accumulated anywhere else in the world.’


Interestingly, Tallet and Lehner argue that Merer and his men represented not vast slave labour, exploited by a biblical despot, but ‘the employment of a highly skilled, well-rewarded workforce’. Team Great worked in proximity to power – also performing royal guard duties and religious rituals – and were part-paid in luxury cloth. But it is also estimated that four teams like Merer’s might have spent 20 years transporting just the facing stone for the Great Pyramid.  READ MORE...

Egypt's Pyramids of Giza

An ultra-powerful scan of Egypt’s Great Pyramid of Giza could help identify two mysterious spaces that potentially house the legendary tomb of the pharaoh. The watershed study was published last month in arXiv by University of Cornell archaeologists.

“We plan to field a telescope system that has upwards of 100 times the sensitivity of the equipment that has recently been used at the Great Pyramid,” wrote the researchers of the proposed scan, which is titled “The Exploring the Great Pyramid Mission.” They use advanced cosmic ray technology to map the internal structure of the Great Pyramid, which is Egypt’s largest pyramid and the last surviving wonder from antiquity.

The team’s research is based on a study by Scan Pyramid group, which conducted a series of scans between 2015 and 2017 that analyzed muons — cosmic particles that regularly fall on Earth — to detect any voids, Live Science reported. Muons react differently to air and stone and are therefore ideal for mapping air pockets in stone structures such as pyramids.

The scientists found two spaces, the larger of which measures 98 feet long and 20 feet high and sits above the grand gallery. Meanwhile, the smaller void is located near the citadel’s north face.

And while neither void’s function is clear, scientists speculate that the large one could lead to the secret burial chamber of the pharaoh Khufu (reign circa 2551 B.C. to 2528 B.C.), for whom the Great Pyramid was originally constructed in the 26th century B.C.

In order to peer inside the void, researchers plan to scan the area with supercharged cosmic ray muons, which are 100 times more powerful than the ones used in the prior scan.

Utilizing them will allow researchers to “image muons from nearly all angles and will, for the first time, produce a true tomographic image [three-dimensional internal images created by analyzing waves of energy] of such a large structure,” per the study.  READ MORE...
