Summary
Serpent Mound is an earthwork of a snake seizing a huge egg. It dates from a time period
without any written records. For that reason it represents one or more stories. It is shown, that
it tells the well-known story of the Egyptian discovery of America and the Biblical Flood. - In
c.1100 BC the monument was updated by placing a heap of stones in the center of the egg.
With this new feature the monument also tells the story of the metal trade and the Dardanus
Flood. Serpent Mound is one of the most important monuments of North America. It is part of
our worldwide cultural heritage.
Introduction
Great Serpent Mound is a prehistoric effigy mound near the village of Peebles, southern Ohio,
at 39°N. The earthwork appears to represent a giant snake, which is slowly uncoiling itself
and about to seize a huge egg within its extended jaws (Figs.1-4). Following all the curves, it
is about a quarter of a mile long, near its body part c.20 feet (6.1m) wide and on the average
c.4.5 feet (1.4m) high. The Serpent is located on a wedge-shaped, slightly convex ridge, whe-
re it overlooks the Ohio Brush Creek flowing 90 feet (28m) lower in the valley. It is situated
on the east bank of this Creek, 40km due north of the place where it empties in the Ohio
River. (The Creek is small compared to this River. Near the monument it has a width of c.18
meters, and the Ohio has a width of about 500 meters.)
The map shows that the town of Hillsboro (or Hillsborough), 24km NW of Serpent Mound,
was an ancient center in this region. As its name suggests, it is located higher than Serpent
Mound (230m), at an elevation of 342m above sea-level. Somehow, it might be related to the
monument. - Finally, it should be noted that the earthwork is situated in an area with a unique
geological structure, which contains faulted and folded bedrock. It appears, that long ago the
ground was struck by an astroide, which is a big meteorite. It appears, the makers of Serpent
Mound were aware of this geological anomality, having a diameter of about 6km. (Refs.1-5)
Description
Basically, the monument consists of three parts: the coiled tail, the twisted body of the Ser-
pent, and the endpart, containing the head of the snake, the large egg, and maybe a small
mound beyond it. A correct description should start with the coiled tail (Fig.1).
The beginning of the tail is small. It has a width of 2 feet (0.6m) and a height of 1 foot (0.3m).
It points 20°NNW to the center of the egg at a distance of c.460 feet (140m). The tail curls to
the left, against the daily movement of the Sun. It gradually increases in size, until it reaches a
width of c.20 feet (6.1m) and a height of c.4.5 feet (1.4m) at the start of the body of the snake,
which is at a direction of 30°ENE from the start of its tail. The triple coiled tail has an outer
diameter of c.100 feet (30m).

2. The body of the Serpent curls slowly to the left, again, against the movement of the Sun. It
consists of four bulges pointing in eastern directions, each of these having the shape of a co-
sinus. The eight zigzags finish at a straight piece of line, which belongs to the head of the
snake. Including the twists of the body, the overall width of this part is about 60 feet (18.3m).
The head of the Serpent starts with a straight piece, pointing 26°WNW. It points to the triang-
ular part, which contains an upper jaw having an inside length of 61 feet (18.6m), and a lower
jaw with a shorter, inside length of 56 feet (17.1m). On the average each of the banks are 58.5
feet (17.8m) long and 17 feet (5.2m) wide. At the throat of the snake the thick wall is 30 feet
(9.2m) wide and 5 feet (1.5m) high. At an inside distance of 47 feet (14.3m) from the throat is
a crescent shaped wall of the same width (17 feet), which is the edge of the mouth. The ex-
tremities of this crescent are 75 feet (22.9m) apart. The egg starts at an inside distance of 9
feet (2.7m) from the mouth.
The egg is 120 feet (36.6m) long, and 60 feet (18.3m) wide, both measured from the outside.
The bank is here c.4 feet (1.2m) high and 18 feet (5.5m) across. Near the center of the enclo-
sed area is a small mound of stones, which was formerly much larger. – Behind the egg in the
west appears to be a low triangular mound at an inside distance of maybe c.9 feet (2.7m). Its
east side has a length of c.32 feet (9.8m), about equal to the length of its axis to the west.
The dimensions of parts of the earthwork may be of importance for the explanation of the mo-
nument. However, we are facing problems in the choice of these parts, and how to measure
these dimensions. Sometimes, we are not completely sure if a part has been well preserved
over the centuries involved. - The distance from the start of the tail across the deep gully in
the hillside to the west end of the egg, pointing 26°NNW, is 496 feet (151m). To the center of
the egg appears to be 496-36= 460 feet (140m). From the outer edge of the coiled tail to the
west end of the egg is 496+60= 556 feet (170m).
The length of the serpent along the dorsal ridge to the throat, following all the curves, and
from the throat directly to the west end of the egg, is 1348 feet (411m). However, (via the
throat) to the tip of the upper jaw is 1254 feet (382m). (Via the throat) to the crescent is
1254-61+47= 1240 feet (378m). To the west end of the egg is 1240+3+120= 1363 feet
(416m). From the tip of the upper jaw to the west end of the egg is 1254+120= 1374 feet
(419m). Including the upper half of the cresent and part of the upper half of the egg is
1374+75= 1449 feet (442m). It appears, that only the last distance, following all the curves, is
really important (as shown below).
The Serpent Mound was first mapped in 1815. In 1846 it was surveyed for the Smithsonian
Institution by E.G. Squier and E.H. Davis. Their book Ancient Monuments of the Mississippi
Valley (1848), published by the Smithsonian, included a detailed description and map of the
Serpent Mound. (Refs.1-5)

(Refs.1,2). (c.2300 BC, Adams County, Ohio)
Religious Meaning
Serpent Mound is located at 39°N. The southern Aleutian Islands near the Bering Sea are lo-
cated at the complementary latitude of 90-39= 51°N. It means the monument dates from after
the Egyptian discovery of America, c.2570 BC. It is located at the latitude of the West Azo-
res, at 39°N. It means it dates from after the discovery of the Return Route across the Atlantic
from Newfoundland to the Azores, c.2505 BC. From 2500 to 1200 BC America was part of
the Egyptian World Empire (Atlantis). It was a colony of Egypt. So, it appears the makers of
Serpent Mound believed in the Egyptian SunGod Ra.

4. In the hierarchy below this highest God were two other gods, the sungod Horus and the
moongod Osiris. The kings and pharaohs were the substitutes of these lower gods. Horus was
the god of the Old World, the Land of the Living, in the monument represented by the coiled
tail of the Serpent. Osiris was the god of the New World, the Realm of the Dead, literally the
“Underworld”, or America, here represented by the egg in the west. It was all created by
Maat, the Egyptian goddess of law and order in the universe. She is represented by the twisted
body of the Serpent, because the wheel of the law is moving in time. She connected the Old
World with the New World, and she took care for an everlasting balance between them.
(Refs.6-11)
Discovery of America
Basically, the monument consists of three parts, encoding the Nile Delta, at 30°N. It is the e-
conomic center of Egypt, the greatest civilization on Earth. The triple coiled tail of the Ser-
pent confirms it. Its round shape symbolizes the Old World. The tail turns to the left, against
the daily movement of the Sun. So, people sailed from west to east. The end of the tail points
30°ENE. So, people sailed from the Nile Delta, along the east coast of China, at 30°N, in
northeastern direction.
Serpent Mound is located at 39°N. So, America was discovered via the southern Aleutian Is-
lands, near the Bering Sea, at the complementary latitude of 90-39= 51°N. The body of the
Serpent consists of four bulges, pointing to the east, which correspond to the Fourth Dynasty.
The head of the Serpent is the fifth feature, encoding the 5th king. So, the 5th king Menkaure
(Mycerinos, c.2580-2562 BC) of the Fourth Dynasty discovered the New World (Fig.1).
The large egg symbolizes this New World. The head of the snake points in northwestern
direction, where America was discovered. Brush Creek symbolizes the Pacific Ocean. The lo-
wer jaw of the head represents the Aleutian Islands. The upper jaw symbolizes a second cros-
sing. So, on the return route king Menkaure discovered the crossing of the Bering Strait.
Serpent Mound is located on the east bank of Brush Creek, which now symbolizes the Atlan-
tic Ocean. So, it also describes the discoveries in the east. The triple coiled tail encodes the
sailing direction of the Southern Crossing, from the Cape Verde Islands to South America,
with the wind and the current, 30°SSW. The four bulges of the body and the head of the snake
form together five units, corresponding to its destination, Cape São Rock, Brazil, at 5°S, but
also the Fifth Dynasty. The round tail and the egg form together two units, encoding the sai-
ling distance of 2 Moiras, or 20°, but also the 2nd king. So, the second king of the Fifth Dy-
nasty, Sahura (c.2510-2498 BC), discovered the Southern Crossing.
The round tail and the egg form together two units, encoding the (initial) sailing direction
from Cape Race, Newfoundland, 20°ESE, and the sailing distance of 2 Moiras, to the two is-
lands of the West Azores. It is the return route, with the wind and the current, to the Old
World. Serpent Mound is located at 39°N, which is the latitude of the West Azores. The
round tail and the egg also encode the second king. The lower and upper jaw of the head of
the snake confirms it. So, the 2nd king Sahura also discovered this second crossing. The axis
from the start of the tail through the center of the egg points 20°NNW, confirming it.
The round tail, the egg, and the head of the snake form together three units, encoding the Nor-
thern Crossing of the Ocean at the complementary latitude of the Nile Delta, at 90-30= 60°N.
The head of the snake points NW, in the direction of the initial sailing direction. One crossed
from the Shetland Islands via the south point of Greenland to Cape Chidley, Canada. This

5. third crossing via these three landpoints was discovered by the 3rd king. The head of the
snake not only has an upper and lower jaw, but also a mouth. So, the third king of the Fifth
Dynasty, Nefererkare (c.2498-2478 BC), discovered the Northern Crossing.
The three mentioned units encode Abaco Island, Northern Bahama’s, 3° below the Nile Delta,
at 30-3=27°N. The round tail and the egg correspond to the latitude of Bermuda, 2° above the
Nile Delta, at 30+2= 32°N. It is the start of the last discovered crossing of the Ocean. The tri-
ple coiled tail, the body and head of the snake, and the egg form together 3+5+1= 9 units,
confirming Bermuda, 9° above the holy Tropic of Cancer, at 23+9= 32°N.
At midsummer day the Sun is at right angles above the Tropic of Cancer. The slow northerly
movement of the Sun turns into a southerly movement. So, one believes in the Egyptian Sun-
God Ra. The holy Tropic of Cancer crosses the River Nile, at 23°N. It is the center of the
Southern Egyptian Empire, but also of the Sun religion.
The 9 units correspond to the nine islands of the Azores. Serpent Mound is located 9° above
the Nile Delta, at 30+9= 39°N, confirming it. So, the return route from Abaco Island via Ber-
muda to the Azores was discovered by the 9th and last king Unas (c.2403-2370 BC) of the
Fifth Dynasty. The latitude of the Nile Delta, at 30°N, encodes the long sailing distance from
Bermuda to the Azores, with the wind and the current, 3 Moiras, or 30°.
The town of Hillsboro and the city-center of Dayton point 40°NNW from Serpent Mound,
confirming the Fourth Dynasty when America was discovered. The total length of the monu-
ment, following all the curves, equals 444 meters, or 4 millimoiras, confirming it. They also
point 90-40= 50°NW, confirming both the 5th king Menkaure who discovered America, and
the Fifth Dynasty, when all Atlantic crossings were discovered. (Refs.10-18)

6. Fig.2 Great Serpent Mound as it looks today. At the left side above Brush Creek. View from
the southeast (Ref.37). (c.2300 BC, Adams County, Ohio)
Biblical Flood
Then, suddenly, a huge Comet appeared in the sky. The egg symbolizes the Head of the Co-
met, and the Serpent its Tail. The wedge-shaped ridge below the monument confirms it. The
ridge, and the Brush Creek besides it, show the Comet consisted of a huge amount of stones
and water. The round tail of the snake shows the Flood happened because of a cosmic collisi-
on of the planet Earth with the Tail of a Comet (or Comet Swarm). Long ago the area was
struck by an astroide, confirming the astronomical meaning of Serpent Mound.
The three coils of the tail encode the 30 days of the month. The triangular head of the snake
refers to another 30 days. So, the Earth stayed in the Tail of the Comet for a time period of
two months, or 2x30= 60 days. The falling stones caused huge forest-fires, and because of
melting ice there were torrential rains, and huge floodings everywhere. It was completely dark
on Earth. This time period was probably the worst.
The whole climate was completely disrupted. The length of the egg equals twice its width. So,
there was a second time period of 60 days. The torrential rains and floodings continued, and it
became bitterly cold. Slowly the terrible rainfall changed into snow and hail storms. The 9
units of Serpent Mound refer to the North Pole, at 90°N. Many people died from starvation. It
was a worldwide Disaster.
The Serpent Mound devides the surface area of the ridge in two (Fig.1). The eastern area
represents the first time period of 2 months, and the western area is the second time period of
2 months. The four bulges of the body of the snake confirm the total duration of the Catastro-
phe, 2+2= 4 months, or 4x30= 120 days. The total length of the monument, following all the
curves, equals 444 meters, or 4 millimoiras, confirming it.
Casualties
Besides the four bulges, the snake has a triple coil, illustrating the millions of people on Earth
before the Flood (a number of 4+3= 7 figures). The head is the 8th unit of the snake. The four
bulges and the head show the initial world population was 4.8 million men. The egg repre-
sents the 9th unit of the monument. It refers to the East Cape of North America, on New-
foundland, 9° above Serpent Mound, at 39+9= 48°N. This latitude confirms the initial world
population.
The length of the egg equals twice its width. It illustrates that about half of the world popula-
tion died (circa 2.4 million men). The four bulges, the head of the snake and the egg form to-
gether 4+1+1= 6 units, encoding 2.6 million casualties (54%). The axis through the head and
the egg points 26°WNW, confirming it. The axis from the center of the tail to the west end of
the egg points 26°NNW, confirming it. Serpent Mound is located 39-13= 26° above the con-
tinent of South America, confirming it, again.
Basically, the monument consists of three parts: the coiled tail, the twisted body of the Ser-
pent, and the endpart. These three units refer to Cape Hatteras, the East Cape of the U.S., 3°
below Serpent Mound, at 39-3= 36°N. This Cape refers to the circumference of the planet
Earth, 36 Moiras, or 360°, which shows it was a woldwide Catastrophe. The complementary
latitude, at 90-36= 54°N, confirms the percentage of casualties, 54%. The relative latitude of
the East Cape of North America confirms this percentage, again: (48/90)x100= 54%.

7. The length of the egg equals twice its width. It also illustrates that about half of the world po-
pulation survived. The egg and the head of the snake form together 2 units, confirming the
number of survivors, 4.8-2.6= 2.2 million men. Most of them were seriously injured. Both the
round tail and the egg, and the round tail and the head, each form two units, confirming it.
The SW Cape of Greenland, at 61°N, is located 61-39= 22° above Serpent Mound, confir-
ming it, again. Greenland consists of stone and ice. Traditionally, it always symbolized the
Head of the Comet, with the North Atlantic Ocean below it, as its Tail.
The Serpent Mound devides the surface area of the ridge in two. The eastern area symbolizes
the 2.6 million people who perished (54%), and the western area represents the 2.2 million
people who survived.
The three coils of the tail, the four bulges of the body, and the head of the snake form together
3+4+1= 8 units. These correspond with the total precipitation during the Flood, about 80 mi-
cromoiras= 80x0.11= c.8.9 meters of water. Cape Race, Newfoundland, at 47°N, is an impor-
tant starting point for the return route to the Azores. It is located 47-39= 8° above Serpent
Mound, confirming it.
The four bulges and the head of the snake form together five units, encoding the Fifth Dynas-
ty, which was ended because of the Comet Catastrophe. The egg is the 6th unit, representing
the weak Sixth Dynasty, when the Flood occurred. The round tail (with its three coils) enco-
des the first king Teti (c.2370-2338 BC). It happened in c.2344 BC during his reign (tree-ring
dating). The latitude of the SW Cape of Greenland, at 60+1= 61°N, confirms that it happened
in the Sixth Dynasty during the reign of the 1st king Teti.
The Flood ended all ancient civilizations on Earth, including the Old Kingdom of Egypt. It is
very likely, that the Serpent Mound in Ohio dates from the Sixth Dynasty (c.2370-2189 BC).
(Refs.19-27)

Serpent Mound, Adams County, Ohio)
Serpent Mound II (c.1100 BC)
Metal Trade
In the center of the egg is a heap of stones (Fig.1). This feature is completely different from
the earthen walls in the rest of the monument. It appears, that it was added to the original mo-
nument at a later date. Serpent Mound was updated because of new, important developments
in America.
Copper
Serpent Mound contains a total of 9 units, corresponding to Isle Royale, Lake Superior, 9° a-
bove the monument, at 39+9= 48°N. It was the center of copper mining in North America.
The 9 units also correspond to the density of copper, 9 g/cm3 (nine times heavier than water).
The tail of the Serpent in the south has three coils, encoding the Mississippi Delta, at 30°N. It
shows, that 3/5, or 60%, of the copper was shipped along the Mississippi River to the south.
The egg and the head of the snake encode the mouth of the St. Lawrence River, 20° higher, at
30+20= 50°N. It shows, that 2/5, or 40%, of the copper was transported to the east.
The Serpent contains a total of 3+4+1= 8 units, which shows that tens of millions of copper
ingots were shipped to the Old World (a number of 8 figures). The egg is the 9th unit of the
monument, referring to Isle Royale, at 39+9= 48°N. The width of the egg is half of its length.
So, the overall export was 48/2= 24 million ingots. The Serpent Mound devides the surface
area of the ridge in two, confirming it.

9. For a long time past the noble metals were weighed in units of carats, corresponding with 0.20
gram. The carat is the constant mass of a seed of the St. John’s bread or carob tree (Ceratonia si-
liqua). The Serpent contains a total of 8 units. The four bulges and the head form together 5
units. So, the Standard Ingot will have a mass of 80,000 carats (a number of five figures), or
80x0.20= 16 kg.
It means, that the overall export of copper across the Ocean would be (24x16=) c.384,000
tons. It has been estimated by others in the field, that a total amount of 250 to 500 thousand
tons of copper had disappeared from the mining area. So, our conclusion is that its destination
can now be understood.
Tin
In the Old World bronze was made by alloying the copper with 10% tin. The heap of stones in
the center of the egg is the 10th unit of the monument, confirming it. Tin was a very scarce
metal. Although generally unknown, a lot of it was imported from South America. Isle Roy-
ale is located 18° above the Mississippi Delta, at 30+18= 48°N. It also refers to the tin mines
near the present town of Oruro, Bolivia, at 18°S.
The tin was transported (as ingots) along the coast to the north, and from the Pacific to the At-
lantic. Serpent Mound has a total of 9 units, encoding the isthmus of Panama, at 9°N, as well
as the nine islands of the Azores. In the Bronze Age the overall export of tin from the menti-
oned site was 10% of the copper, or 2.4 million tin ingots (a number of 7 figures). The triple
coiled tail and the 4 bulges form together 3+4= 7 units, confirming it. It also corresponds with
the density of tin, 7 g/cm3 (seven times heavier than water). The quantity corresponds with
c.38,400 tons of tin.
Silver and Gold
Silver was found together with tin. Including the heap of stones the monument has 9+1= 10 u-
nits. The egg will be the 11th unit, encoding the density of silver, 10+1= 11 g/cm3 (eleven ti-
mes heavier than water). - According to the normal counting the Serpent contains 8 units, and
the important egg is the 9th unit. So, both encode an overall export of 90 million carats (a
number of eight figures), or 90x0.20= 18 tons of silver. Most of the silver in the Old World
was imported from Bolivia, in South America.
Gold is a completely different story. In this early time period it was almost exclusively traded
at the mouth of the Amazone River. Including the heap of stones the monument has 9+1= 10
units. The old monument contained 9 units. So, the egg will be the 10+9= 19th unit, encoding
the density of gold, 19 g/cm3 (nineteen times heavier than water). - The head of the snake and
the egg form together two units, encoding the important latitude, at 2°S. The Serpent contains
8 units. The four bulges and the head of the snake form together 5 units. Both encode an
overall export of 50 million carats (a number of eight figures), or 50x0.20= 10 tons of gold.
However, most of the gold in the Old World was imported from Africa.
The four bulges of the body of the Serpent illustrate the transport of four different metals from
America to the Old World. Including the heap of stones the monument has 9+1= 10 units. So, the
heap of stones might represent the 10+10= 20th unit, encoding the Twentieth Dynasty. It
determines the date of the heap of stones (Serpent Mound II, c.1100 BC). The axis from the
center of the tail to the heap of stones points 20°NNW, confirming it.

10. So, the metal trade lasted from the start of the Fifth Dynasty till the start of Twentieth Dynasty,
which is from c.2500 BC to c.1200 BC, a time period of about 1,300 years. The three walls of
the head of the snake confirm these 10+3= 13 centuries. (Refs.28-32)

the northwest (Ref.38). (c.2300 BC, Adams County, Ohio)
Dardanus Flood
Then, suddenly, a huge Comet appeared in the sky. The egg symbolizes the Head of the Co-
met, and the Serpent its Tail. The wedge-shaped ridge below the monument confirms it. The
ridge, and the Brush Creek besides it, show the Comet consisted of a huge amount of stones
and water. The round tail of the snake shows the Flood happened because of a cosmic collisi-
on of the planet Earth with the Tail of a Comet (or Comet Swarm). Long ago the area was
struck by an astroide, confirming the astronomical meaning of Serpent Mound.
The three coils of the tail encode the 30 days of the month (Fig.1). The four bulges of the
body of the snake show the Earth stayed in the Tail of the Comet for a time period of 40 days.
The total length of the monument, following all the curves, equals 444 meters, or 4 milli-
moiras, confirming it. The falling stones caused huge forest-fires, and because of melting ice
there were torrential rains, and huge floodings everywhere. It was completely dark on Earth.
This time period was probably the worst.
The triangular head of the snake also encodes the 30 days of the month. The four bulges show
there was a second time period of 40 days. The torrential rains and floodings continued, and it
became bitterly cold. Slowly the terrible rainfall changed into snow and hail storms. The 9
units of Serpent Mound refer to the North Pole, at 90°N. Many people died from starvation. It
was a worldwide Disaster.
The Serpent Mound devides the surface area of the ridge in two. The eastern area represents
the first time period of 40 days, and the western area is the second time period of 40 days. The
Serpent contains a total of 3+4+1= 8 units, confirming the total duration of the Catastrophe,
40+40= 80 days. Cape Race, Newfoundland, at 47°N, is an important starting point for the
return route to the Azores. It is located 47-39= 8° above Serpent Mound, confirming it.

11. Casualties
Including the heap of stones the monument has 9+1= 10 units. The Serpent contains 8 units.
So, the head of the Serpent might be considered as the 10+8= 18th unit. It encodes the world
population before the Flood, 18 million men. The old monument had a total of 9 units. So, the
egg might also be considered as the 9+9= 18th unit, confirming it.
The round tail, the head of the snake, and the egg form a total of 3 units, referring to Cape
Hatteras, the East Cape of the U.S., 3° below Serpent Mound, at 39-3= 36°N. The Cape refers
to the circumference of the planet Earth, 36 Moiras, or 360°, which shows it was a worldwide
Catastrophe. The width of the egg equals half of its length. So, it also refers to the civilization
around the south point of the Gulf of Campeche, Mexico, at 36/2= 18°N. It is the center of the
Realm of the Dead. It confirms the initial world population of 18 million men.
The four bulges of the body of the snake encode the c.4.0 million casualties. The total length
of the monument, following all the curves, equals 444 meters, or 4 millimoiras, confirming it.
The latitude of Serpent Mound, at 39°N, confirms the c.3.9 million victims. – The head of the
snake and the egg form together 2 units, encoding the additional 2.0 million victims because
of system collapse (lack of government). The axis from the center of the tail throught the heap
of stones in the egg points 20°NNW, confirming it.
Cape Farvel, the south point of Greenland, is located at the complementary latitude of the
Nile Delta, at 90-30= 60°N. It confirms the 4.0+2.0= c.6.0 million casualties of the Dardanus
Flood (32%). Greenland consists of stone and ice. Traditionally, it always symbolized the
Head of the Comet, with the North Atlantic Ocean below it, as its Tail. The island of Bermu-
da, at 32°N, confirms the percentage of casualties, 32%.
Including the 3 walls of the head of the snake, the old monument contained a total of 9+3= 12
units, confirming the number of survivors, 18-6= 12 million men. Many of them were seri-
ously wounded. The southern Aleutian Islands are located 51-39= 12° above Serpent Mound,
confirming it. Abaco Island, northern Bahama’s, is located 12° below the monument, confir-
ming it, too. The south point of the Gulf of Campeche, Mexico, is located 30-18= 12° below
the Nile Delta, confirming it, once again.
The four bulges and the head of the snake form together 5 units, encoding the precipitation
during the Dardanus Flood, 50 micromoiras= 50x0.11= c.5.5 meters of water. The comple-
mentary latitude of Serpent Mound, at 90-39= 51°N, confirms it. The town of Hillsboro and
the city-center of Dayton point 50°NW from the site, confirming it, again.
Including the heap of stones the monument has 9+1= 10 units. So, the heap of stones might re-
present the 10+10= 20th unit, encoding the Dardanus Flood in the Twentieth Dynasty. The axis
from the start of the tail to the heap of stones points 20°NNW, confirming it. The Serpent Mound
devides the surface area of the ridge in two, confirming it, again.
The round tail and the egg form 2 similar units. Together with the head of the Serpent it forms 3
units. So, the Dardanus Flood occurred during the reign of the 2nd king Ramses III (1184-1153
BC). It happened at the end of his reign, in 1159 BC (tree-ring dating). The axis from the center
of the round tail to the heap of stones points 20°NNW, and to the start of the body of the Serpent
30°ENE, confirming it.

12. The triple coiled tail of the Serpent turns to the left, against the daily movement of the Sun. It
usually means, that the monument not only deals with religion, but also with history. The four
bulges of the snake show the earthwork tells four important stories: the Egyptian discovery of
America, the Biblical Flood, the metal trade, and the Dardanus Flood. (Refs.33-36)
