THE SWAN STONE
(Burrows Cave, near Olney, Illinois)

Summary
The Swan Stone from Burrows Cave, Illinois, bears a petroglyph of a serpent with a large
head in the shape of the wing of a bird. It tells the famous story of the discovery of the sailing
routes across the Atlantic during the Old Kingdom of Egypt. Finally, after a long struggle of
several millennia people were able to reach the back side of the planet Earth. However, imme-
diately after this success was a Comet Catastrophe which resulted in the Biblical Flood (c.
2344 BC). Because of a precipitation of nine meters of water within a time period of four
months more than half of the world population perished (2.6 million men). It resulted in the
end of all ancient civilizations on Earth, including the Old Kingdom itself.
Introduction
The Swan Stone is a black slate stone having a length of 20 cm, a width of 15 cm, and a
height of c.8 cm (Refs.1-3). It bears a nice petroglyph of a serpent finishing in a kind of wing
(Fig.1). It is a so-called Burrows Cave artifact, found in a cave along a branch of the Little
Wabash River near the town of Olney, in southern Illinois. This cave is situated at a distance
of 100 miles due east of Cahokia, the ancient capital of North America. Further due east is
Washington D.C., the present capital of the USA. All these very important places are located
at the holy latitude of 39°N. It is the latitude of the West Azores, in the middle of the North
Atlantic Ocean. These were the westernmost islands of the civilization in the Old World.
Discovery of America
The Egyptian discovery of America occurred via the southern Aleutian islands, at the south si-
de of the Bering Sea, at the complementary latitude of 90-39= 51°N. In antiquity, the use of
complementary latitudes was very common. In the Old World latitudes and complementary
latitudes were already in use for thousands of years, as early as 4700 BC. One degree above
Burrows Cave is the important latitude line of 40°N. It shows this discovery happened in the
Fourth Dynasty of Egypt. The complementary latitude of 90-40= 50°N illustrates the 5th king.
It was the 5th king Menkaure (Mycerinos, c.2580-2562 BC) of the Fourth Dynasty who disco-
vered America (Refs.4-9)!
However, the complementary latitude of 90-40= 50°N also encodes the Fifth Dynasty, when
all Crossings of the Atlantic were discovered. The Swan Stone should be placed in a vertical
position, as shown in Fig.1. The surface of the Stone symbolizes the North Atlantic Ocean.
The two tips of the Tail and the three feathers of the Wing confirm the 2+3= 5th Dynasty,
when these important discoveries were made. The two tips of the Tail at the bottom represent
the 2nd king Sahure (c.2510-2498 BC), who discovered the two southern Crossings. The three
feathers of the Wing on top represent the 3rd king Nefererkare (c.2498-2478 BC), who disco-
vered the third, northern Crossing.

2. A ship sailed from the Cape Verde Islands, with the wind and the current, over a distance of 2
Moiras= 20 degrees, to Cape São Roque (the holy Rock), Brazil, at 5°S. It illustrates that the
2nd king Sahure of the Fifth Dynasty discovered the Southern Crossing. The sailing direction
of 30°SSW shows it was an Egyptian king from the Nile Delta, at 30°N. The same ship sailed
from Newfoundland, with an initial sailing direction of 20°ESE, with the wind and the cur-
rent, over a distance of 2 Moiras to the two islands of the West Azores, and further to the five
islands of the Central Azores. It confirms, that the 2nd king Sahure of the Fifth Dynasty also
discovered the Return Route to the Old World. The Swan Stone shows the whole sailing route
to the West Azores, at the holy latitude of 39°N (Burrows Cave). The circle in the center of
the serpent illustrates this round trip. Together with the previous discoveries, it was also the
first circumnavigation of the planet Earth.
Another ship sailed from the Shetland Islands, via the south cape of Greenland, to Cape Chid-
ley, Canada. These three land points, represented by the three feathers, are located at the com-
plementary latitude of the Nile Delta, at 90-30= 60°N. It confirms that the 3rd Egyptian king
Nefererkare discovered the third, northern Crossing. He was the brother of king Sahure, as
suggested by the connection on the Swan Stone. - This Stone was found at Burrows Cave, 9
degrees above the Nile Delta, at 30+9= 39°N. It suggests, that the 9th king Unas (c.2403-2370
BC) discovered the Return Route via Bermuda to the West Azores. Bermuda is located 9
degrees above the holy Tropic of Cancer, at 23+9= 32°N. He sailed, with the wind and the
current, over 3 Moiras= 30 degrees from Bermuda to the 9 islands of the Azores. The three
feathers of the Wing appear to confirm the long sailing distance (Refs.6,7).
The Tropic of Cancer is the holy line of the Sun religion. At midsummer day the Sun is there
at right angles above. The slow northerly movement of the Sun turns into a southerly move-
ment. So, one believes in the Egyptian SunGod Ra. This latitude line crosses the River Nile at
23°N, as shown by the 2 tips of the Tail and the 3 feathers of the Wing (20+3= 23). It is the
center of the Southern Egyptian Empire, but also the center of the Sun religion. King Sahure
as well as king Nefererkare were the substitutes of this SunGod (Refs.4-9). In the Egyptian
tradition these kings were represented by parts of an animal, by the split Tail of a Serpent, and
by the Wing of a Swan, respectively.

3. Fig.1 The Swan Stone tells the story of the discovery of the sailing routes across the Atlantic
in the Fifth Dynasty and the Comet Catastrophe after it, when more than half of the world po-
pulation perished. (First Millennium BC, Burrows Cave, near Olney, Illinois) (Refs.1-3)
Comet Catastrophe
When studying the Swan Stone a special feature of the petroglyph becomes apparent. The
Wing on top is much larger than the split Tail at the bottom. This is surprisingly, because the
two southern Crossings discovered by Sahure are much more important than the Northern
Crossing discovered by Nefererkare. So, it appears the Stone is telling an additional story. The
circle in the center is the planet Earth, and the serpent now appears to represent a Comet (or
Comet Swarm) (Refs.10-20).
The lower half of the wing shows what appears to be three additional feathers. These empha-
size the central feather on top of the glyph, representing the south cape of Greenland. In anti-
quity, the island of Greenland symbolized the Head of a Comet, with the North Atlantic Oce-
an below it as its Tail. Like the Head of a Comet Greenland consists of stone and ice, and like
the Tail of a Comet the Ocean contains an awful lot of water. The 3+3= 6 feathers confirm the

4. latitude of the south cape of Greenland, at 60°N. It shows this Comet Catastrophe happened in
the Sixth Dynasty. It occurred because of a cosmic collision of the planet Earth with the Tail
of a Comet (Refs.21-26).
The circle in the center of the serpent now symbolizes the Moon, and the three feathers on top
are the 30 days of the month. The split Tail shows the planet Earth was inside the Tail of this
Comet for 2 Months, or 2x30= 60 days. The latitude of the south cape as well as the 3+3= 6
feathers of the wing confirm it. The falling rocks caused hugh forest fires, and the melting ice
of the Comet caused torential rains. There were hugh floodings everywhere. It was completely
dark on Earth. This time period was probably the worst.
After these two months the Earth left the Tail of the Comet. However, the three feathers on
the lower half of the wing also symbolize the 30 days of the month. The whole climate on
Earth was completely disrupted. The split Tail shows the planet Earth was outside the Tail of
the Comet for another 2 Months, or 2x30= 60 days. The latitude of the south cape as well as
the 3+3= 6 feathers of the wing confirm it. The torrential rains continued, but it also became
bitterly cold. So, these rains were changing in ferrocious snow and hail storms. The hugh
floodings continued, and many people died from starvation.
The serpent encircles the planet Earth. It shows it was a worldwide Disaster. The 2 tips of the
tail and the 6 feathers of the wing encode a total number of 2.6 million casualties. The third
feather on the lower half of the wing has not fully been carved. The 2 tips of the tail and the 5
remaining feathers correspond to 2+5= 7 units, encoding the 7 figures of this number. The 3
feathers on top count for two (Fig.1). Together with the 6 feathers of the Stone these encode
the circumference of the planet Earth, 36 Moiras, or 360 degrees. It confirms it was a world-
wide Disaster. The complementary latitude of 90-36= 54°N encodes the percentage of casual-
ties, 54%. So, the world population before this Calamity was (100/54)x2.6= 4.8 million peo-
ple. The number of survivors was 4.8-2.6= 2.2 million men. Many of them were seriously in-
jured.
The width of the serpent increases from 1 unit at the bottom, via 2 units around the Earth to 3
units at the top (Fig.1). The total number of 1+2+3= 6 units confirm the Biblical Flood hap-
pened in the Sixth Dynasty. The single unit at the bottom shows it happened during the reign
of the 1st king Teti (c.2370-2338 BC). Tree-ring dating indicates it happened c.2344 BC. The
2 units around the Earth confirm it was a two-stage event, having a total duration of 60+60=
120 days. The three feathers on top point to the latitude line through the south cape of Green-
land, at 60°N. It corresponds to the approximate periodicity of the Comet, c.600 years (a num-
ber of 3 figures). The 2 tips of the tail and the 3 feathers of the wing indicate an average lati-
tude of 2.5 degrees above the Nile Delta, at 30+2.5= 32.5°N (Poverty Point, NE Louisiana).
The complementary latitude of 90-32.5= 57.5°N encodes the exact periodicity of 575 years.
The two tips of the tail and the six feathers, or the six units, show, that the total precipitation
during the Flood was about 20+60= 80 micromoiras= 8x1.1= 9 meters of water. The Biblical
Flood had a profound influence on the climate on Earth. The Wing of the Swan points to
Greenland, indicating a much colder climate. The three feathers on top (and below them) il-
lustrate that this colder and dryer time period lasted for three centuries, from c.2344 BC till c.
2000 BC, which is at the start of the Twelfth Dynasty (Middle Kingdom). People used fea-
thers of birds in their coats for protection against these colder conditions (Refs.10-26).

5. Discussion
The 5th king Menkaure (Mycerinos) of the Fourth Dynasty discovered America via the Be-
ring Sea. The American archaeologist G.A. Reisner of the Harvard Museum of Fine Arts was
the leader of the excavation of his Pyramid in Gizeh (near Cairo), between 1906 and 1910. It
might be considered as the first small pyramid of this Dynasty, a tradition which was conti-
nued after him ever since. The slope of its four sides equals 51 degrees, encoding the latitude
of the southern Aleutian islands, at 51°N. King Menkaure is famous for his many beautiful
statues. The name of the land of “Korea” might be derived from this king. It is possible, that
the name of the town of “Mycenae” and the “Mycenaean culture” (1450-1150 BC) are called
after his Greec name. His temple was completely rebuilt in the Sixth Dynasty after a “floo-
ding” (obviously caused by the Comet Catastrophe). (Ref.32)
The 2nd king Sahure of the Fifth Dynasty discovered the two southern crossings of the North
Atlantic Ocean. His Pyramid is the first one located in Abusir (“Home of the god Osiris”), at
the NW side of the Lake, which is just south of Gizeh. The 200-meter long procession road
from the valley temple to his Pyramid is oriented due west. The groundplan of the pyramid
temple is called the conceptual start of all other temples of the Old Kingdom. The walls of the
complex were covered with reliefs having a surface area of c.10,000 square meters. These be-
long to the oldest of their kind. Behind an open space is a passage at right angles for the inte-
rior part of the temple. On the eastern wall are reliefs about sea voyages, one of the earliest a-
bout this subject. In the hart of the temple copper tubing is used for drainage puposes, proba-
bly imported from the Lake Superior region (Refs.27-31). It is probable, that the Sahara desert
is called after this king.
Fig.2 King Sahure (at the right side) as god of the sea (the waves). He discovered the two
southern crossings of the Atlantic. The sailing distances of 2 Moiras= 20 degrees over open

6. sea were the longest crossings ever accomplished. (Pyramid temple of Sahure in Abusir, near
Cairo, c.2500 BC) (Ref.32)
The 3rd king Nefererkare discovered the northern crossing of the Atlantic. His larger Pyramid
was built besides the one of his predecessor Sahure, but more to the west. The slope of its four
sides was clearly steeper compared to the pyramid of Sahure. The 380-meter long procession
road from the valley temple to his Pyramid is oriented due west, again. The complex is espe-
cially known for the Abusir papyri, which deal with the Pyramid of Nefererkare.
The 9th and last king Unas of the Fifth Dynasty discovered the Return Route via the island of
Bermuda to the Azores. His Pyramid is located in North Saqqara, a little southwest of Abusir.
Its size is comparable with the one of Sahure, but the orientation of the 750-meter long, cur-
ved procession road is completely different. Only a small portion of the reliefs are preserved,
but these show sailing ships and people working on copper and gold (from America). South of
the procession road are two 45-meter long boat pits. However, king Unas is especially famous
for the pyramid texts in his burial chamber, the oldest of their kind. It is highly probable, that
these mysterious texts and the many stars on the ceilings refer to the Comet Catastrophe,
which ended the Fifth Dynasty. These stars and pyramid texts were present in almost all pyra-
mids of the next, Sixth Dynasty (c.2370-2189 BC), which was the last one of the Old King-
dom.
The Comet Catastrophe or Biblical Flood happened during the reign of the 1st king Teti of the
Sixth Dynasty. His Pyramid is located close to the one of his predecessor king Unas of the
previous, Fifth Dynasty. It is characteristic for the transition to the standard features of the py-
ramid temples of the Sixth Dynasty. (However, the valley temple near the lake is lacking.)
The walls of his burial chamber were decorated with pyramid texts, and there were stars on
the ceilings, again. His sarcophacus is the first one with pyramid texts, and also the roof of his
chapel was decorated with stars. These all refer to the Comet Catastrophe, which killed more
than half of the Egyptian population, and seriously wounded almost all survivors. In many
cultures on Earth the number “six” (of the Sixth Dynasty) means “death”. The name of king
“Teti” lives on in words like “to test”, “testimony”, and “testament”. The slopes of all Pyra-
mids of the Sixth Dynasty is 54 degrees, encoding the percentage of victims of the Biblical
Food, 54%. The complementary angle of 90-54= 36 degrees shows it was a worldwide Disas-
ter, because the circumference of the Earth is 360 Moiras, or 360 degrees. However, king Teti
also wanted to remind his people to the glorious days of the Old Kingdom. Some square gra-
nit columns in his pyramid complex resemble those of the Fourth Dynasty, and some altars in
his temple resemble those of Sahure, Nefererkare and Unas of the Fifth Dynasty. (Ref.32)
