The Anchor (Northeast
Horizon--Perseus /Cassiopeia): Rising in the northeast where the pillar met the
ground were the "Imperishable Stars" (circumpolar stars). The
Egyptians associated this area with the constellation Taweret, the protective
hippopotamus goddess, and the northern mooring post of the heavens.
The relationship between the
Southwest-to-Northeast (SW-NE) vertical pillar of the Milky Way and the
secondary North-Northeast to South-Southwest (NNE-SSW) directional system is an
extraordinary example of how the landscape of Thebes fused with celestial
geometry during the joint reign of Hatshepsut and Thutmose III.
To the ancient Egyptians,
these two axes were not conflicting: they were perpendicular mirrors of each
other. They represented the ultimate heavenly and earthly harmony. (David Furlong)
1. The Perpendicular Cosmic Cross
In ancient Egyptian
architecture and sacred geography, two interacting lines created a comic
quadrant.
The Earthly Axis
(NNE-SSW): This is the local orientation
of the Nile River as it flows through Thebes; as well as, the deliberate axis
of major monuments.
The Celestial Axis (SW-NE):
This is the exact trajectory of the vertical Milky Way pillar on the night of
the autumnal equinox. (David Furlong)
When the Milky Way stood
perfectly vertical, its SW-NE trajectory cut across the sky at a precise right
angle (90 degrees) to the NNE-SSW river and temple grid. The sky goddess Nut
was literally forming a perpendicular "vault" or protective rib over
the spine of Egypt.
Furthermore, it is the
singular contention of D. Carlton Rossi that the arching body of Nut should not
be restricted solely to the Milky Way. It may also be identified and witnessed
as the seven stars of the Big Dipper. Her head may be identified as a
configuration in the handle. Her arms and legs support her starry frame sharing
four pillars with Shu's two, upright arms.
2. The Mirror of the Two Banks
During Hatshepsut's era,
Thebes was strictly organized by the NNE-SSW axis of the Nile. (David Furlong)
East Bank (SSW): The Temple
of Amun-Ra at Karnak.
West Bank (NNE):
Hatshepsut's Mortuary Temple at Djeser-Djeseru "Deir el-Bahari"
(David Furlong)
When the cosmic pillar
reached its vertical peak on October 9, 1468 BCE (astronomical year), the
dense, glowing Galactic Core anchored itself in the Southwest. This meant the
most brilliant, divine part of the sky was pouring its light down directly over
the Valley of the Kings and the West Bank temples--the sacred realm of the
ancestors, the setting Sun, and Hatshepsut's own eternal resting place.
3. Symmetrical Alignment
with Hatshepsut's Architecture
The main gate of
Hatshepsut's temple faces the winter solstice sunrise to the southeast. The internal
sanctuaries and processional routes align with the local NNE-SSW topography.
The priests stood at Karnak
and looked across the river toward Hatshepsut's temple along the NNE-SSW line.
They saw the vertical Milky Way at 7:00 PM forming a colossal, glowing arch
framing the entire landscape. This bridged the East and West banks.
At exactly 6:00 AM on
October 9, 1468 BCE (astronomical year), the stars Thuban, Pherkad, Kochab,
Kappa Draconis and Pherkad-Kochab Midline (ie. PK-Midline node) did something
extraordinary. They formed a perfect vertical meridian alignment cutting
straight down into the northern horizon at Thebes. This specific
astronomical event is a cornerstone of New Kingdom archaeoastronomy.
The 6:00 AM Spatial
Alignment
This specific cluster of
stars formed a flawless geometric line. The pattern did not repeat itself in
the 18th Dynasty.
The Vertical Plumb Line
The four stars and the
PK-Midline node lined up sequentially like beads on a vertical string, exactly
perpendicular to the horizon. The PK-Midline node was a proxy for draftsmen as
it positioned the mid-point between Pherkad and Kochab. It acted as an
approximate proxy for the center of a perfect square in the Little Dipper bowl
which contained Atum.
The Past, Present and Future
It is rather remarkable (as
an understatement) that these three polestars were represented. Thuban as Alpha
Draconis was the past polestar. Kappa Draconis was the present polestar, and
arguably the most important at the time, as it sat 6 degrees from true north.
Kochab (Beta Ursae Minoris) would be the future polestar as one of the
Guardians of the Gates. With the meticulous records of the ancient Egyptians,
this particular event must have been anticipated for decades.
The Sun is on the Horizon at
6:00 AM
At 6:00 AM, on an equinox at
Thebes, the center of the Sun is crossing the horizon. The sky is already
illuminated by civil twilight, which begins roughly 20 to 24 minutes earlier at
Thebes' latitude (25.7 degrees N). To see these stars for a few minutes before
they vanish into the dawn must be done between 4:45 AM to 5:10 AM (astronomical
twilight).
On that specific date,
morning astronomical twilight occured from 4:00 AM to 5:07 AM local solar time
for a total duration of 26 minutes and 52 seconds. In this range of time, the
Sun is 12 to 18 degrees below the horizon.
The Stars on that Day
Thuban, on that day, was
roughly 4.5-degrees away from the true pivot point of the sky. It was still
highly visible. The Pherkad-Kochab Node on the imaginary line connecting
Pherkad and Kochab was highly significant to priests. When either Pherkad and
Kochab aligned vertically over each other, or aligned vertically with Thuban,
it marked a perfect, mathematically precise True North vector. Kappa Draconis served as a visual stepping
stone to track the arc between the fading pole star (Thuban) and the rising
importance of Kochab. All these stars stood out with crisp clarity.
The Azimuth and Altitude
Angle (4:00 AM local solar time)
The calculated positions for
each target relative to True North (0 degree / 360 degree Azimuth) are as
follows:
Kappa Draconis: 30.0 degrees altitude, 0.5 degrees Azimuth
(compass direction), culminating directly above the North Pole.
Thuban: .6-degrees Altitude, 7.0 degrees Azimuth,
Below the pole, slightly to the North-East.
Kochab: .7-degrees Altitude, 356.0-degrees Azimuth,
Lowest of the group, near North-West.
Pherkad-Kochab: .1-degrees
Altitude, 356.7-degrees Azimuth, lowest of the group, near North-West.
Understanding the Alignment
Mechanics
The positions of these
stellar objects reveals exactly why Egyptian priests tracked them so
obsessively for temple alignments:
The Vertical Plumb
Line: Kappa Draconis was passing almost
perfectly oveer the true spatial position of the North Pole (0.5-degrees
azimuth deviation is completely imperceptible to the naked eye). This means it
was sitting vertically straight up from the ground point of True North.
The Pherkad-Kochab
Balance: Kochab (356.0-degrees) and
Pherkad (357.5-degrees) were clustered together tightly just to the left of the
meridian. Because they were moving counterclockwise, they were preparing to
sweep horizontally beneath the pole.
The Node Position: The midpoint (node) between Pherkad and
Kochab sat roughly 18.1-degrees altitude and 356.7-degrees azimuth, meaning it
was aligned within a mere 3.3-degrees of True North.
Observational Takeaway
An architect stretching a
string or holding a "merjet"
plumb line towards Kappa Draconis at 4:40 AM would have established a
line pointing to True North with exceptional accuracy. This precision enabled
them to square the foundation of a building to the cardinal directions long
before the sun ever broke the horizon.
Over the 27-minute span of
astronomical twilight, all coordinates shifted counter-clockwise around the
North Celestial Pole (NCP) due to the Earth's rotation. Because the planet
rotates exactly 1 degree every 4 minutes, the entire stellar group swept
through a arc of 6.75- degrees around the pivot altitude of 25.7- degrees.
Horizon Coordinates at
Twilight's End (5:07 AM Solar Time)
Kappa Draconis: Altitude 30.0-degree (steady), Azimith 359.9-degrees,
change -0.6 degrees, passing perfectly over the local meridian line.
Thuban: Altitude 22.4-degrees change (rising +0.8
degrees), Azimuth 7.5-degrees changing (Eastward + 0.5 degrees), swinging
upward and slightly right.
Kochab: Altitude 19.1-degrees sinking -0.4 degrees,
Azimuth 356.8-degrees (East ward +0.08 degrees), moving horizontal toward the
meridian.
Pherkad: Altitude 17.8-degrees sinking -0.2 degrees,
Azimuth 358.7-degrees (Eastward = 1.2-degrees), shifting right, closest to the
group.
Pherkad-Kochab Node: Altitude 17.8-degrees, (sinking -0.3
degrees), Azimuth 357.7-degrees (Eastward +1.0 degrees), closing the gap toward
True North.
Key Structural Changes in
the Alignment
Kappa Draconis Hits True
Center: At 4:40 AM, Kappa Draconis was
slightly east of the line (0.5 degrees). By 5:07 AM, it drifted west to
359.9-degrees, positioning itself directly on the true meridian line.
The Pherkad-Kochab Node
Tightens: The imaginary center node between the two Guardians migrated from
356.7-degrees to 357.7-degrees. This brought the node even closer to True
North, tightening the layout accuracy just as the sky became too bright to see.
Vertical Stability: Because these stars were executing a tight
circular pivot near the bottom and top boundaries of their paths, their
vertical altitudes changed by less than a single degree (1 degree) over the
entire twilight duration.
Observational Takeaway
The 27- minute window
operated like a ticking cosmic clock. An architect tracking Kappa Draconis
would watch it slide perfectly onto the vertical plumb line at 5:07 AM,
signaling the exact moment to lock in the north-south axis line right before
the rising blue dawn washed the stars from view.
The interaction between this
northern stellar alignment and the equinox sunrise provides a look into the
geometric precision of New Kingdom temple architects. By locking in the
north-south axis, the stars during twilight automatically establish a perfect
90-degree cross-axis for the equinox sunrise.
The Dual-Axis Alignment
Matrix (October 9, 1468 BCE)
1. The Problem:
Trying to align a temple directly to the sunrise on the morning of the
equinox is visually inaccurate. The glare of the sun distorting through the
morning, horizon haze makes finding the exact center point of the solar disk
incredibly difficult.
The Solution: Egyptian architects used a geometric
cross-axis. By sighting the Kappa Draconis plumb line at 5:07 AM, they laid
down a perfectly straight north-south baseline on the ground. They then used
simple geometric surveying techniques (using cords and stakes to scribe
intersecting arcs) to construct a line exactly 90 degrees perpendicular to it.
2. The 53-Minute Execution Window
5:07 AM (Starlight Fades):
The alignment to Kappa Draconis at 359.9-degrees Azimuth is finalized and
marked with stakes just as the star disappears into the blue sky.
5:07 AM to 6:00 AM (The
Intermission): Workers have exactly 53
minutes of bright civil twilight to construct the perpendicular line extending
straight toward the eastern horizon.
6:00 AM (The
Verification): The Sun breaks the
horizon at an azimuth of exactly 90.0-degrees (True East). Because the ground
axis was constructed using the northern stars, the sun rises perfectly centered
within the eastern gateway of the temple layout, validating their work.
3. Cosmic Balance: The Imperishable and the Reborn
To the Egyptian priesthood,
this alignment was not just math; it was a profound theological statement:
The North Axis: Anchored by the Imperishable Stars (Thuban,
Kochab, Kappa Draconis) that never sank below the horizon, representing
eternity, stability and the afterlife.
The East Axis: Anchored by the Sun (Ra), representing
rebirth, daily renewal, and the living Pharaoh.
By binding these two axes
together at a flawless right angle on the morning of October 9, 1468 BCE
(astronomical year), the temple became a physical mirror of the entire cosmic
order (Ma'at).
The architectural landscape
of New Kingdom Thebes directly showcases this exact type of 90-degree cardinal
and solar geometry, explicitly preserved in the layout of Karnak and the
temples directly across the Nile.
When examining New Kingdom
structures built or expanded during this exact timeframe (such as the reign of
King Hatseptsut and Thutmose III, it is found that the entire sacred landscape
was engineered using this strict geometric grid.
The Great Theban Trans-Nile
Alignment
Rather than just a single
temple, the architects mapped out a massive, multi-kilometer axis that bridged
the East and West banks of the Nile.
1. The Core Baseline: The 116 Degree Solstitial Axis
The primary axis of the
Karnak Temple Complex (on the East Bank) does not point directly east to the
equinox. Instead, it is rotated to an azimuth of 116 degrees.
The Target: This points precisely to the sunrise on the
Winter Solstice, celebrating the rebirth of Amun-Ra.
The Trans-Nile Mirror: The architects extended this exact line
across the river. If one stands in the Holy of Holies at Karnak and look
directly along the temple's central pathway to the west, line of sight strikes
the cliffside Mortuary Temple of Hatshepsut at Deir el-Bahari on the West Bank.
2. How the Polar/Equinox Geometry Applied
While the main pathways
celebrate the winter solstice, the foundation geometry relies completely on the
90-degree right angle derived from the stars.
Symmetry and Rectangular
Layouts:
Every courtyard, pylon
gateway, and obelisk base at Karnak and Deir el-Bahari is constructed out of
interlocking, perfect rectangles. To turn a 116-degree solar axis into a
structurally sound building, the architects had to establish a flawless
26-degree /296-degree cross-axis (exactly 90-degrees perpendicular).
The Stretching of the Cord
(Pedj-Shes): Textual reliefs from the
New Kingdom confirm that pharaohs initiated temple constructions through this
nocturnal ritual. The royal architect and the pharaoh would locate the northern
circumpolar stars (like Pherkad-Kochab node or Kappa Draconis) to drop a true
meridian plumb line.
The Geometric Shift: Once True North (0 degree) and True East (90
degrees) were established on the foundation sand using the twilight window, the
architects simply measured a fixed angular offset (26 degrees clockwise from
East) to lock in the 116 degree solsticial line.This guaranteed that the side
walls of the temples aligned precisely to the true cardinal directions, while
the central aisle aligned to the sun.
The Ultimate Architectural
Synthesis
The New Kingdom temples were
large-scale calculators. By locking down the spatial grid using the
Imperishable Stars at dawn (establishing absolute stability and north-south
alignment), they could accurately offset their angles to capture the dynamic
movements of the Sun god over the course of the shifting year.
Architectural
Implication: If the architectural
layouts of the New Kingdom are consistently hyper-accurate (under 0.1-degrees
of error), it strongly favours a slow-moving, high-stability target like
Thuban-Kappa Draconis or Thuban-Kochab alignment, because human surveyors had
to adjust their alignment ropes without rushing. For example, the midpoint of
Thuban and Kappa Draconis stayed within a fraction of a degree of true north
for over 5 minutes during its transit. However, the Pherkad-Kochab node remains
a viable candidate used as part of their broader, multi-star verification
process.
The Macro-Quadrant Celestial
Cross (4:40 AM Solar Time)
1. The Eastern Anchor: The Pleiades (Mekhat)
The Position: At 4:40 AM,
the Pleiades star cluster was positioned high height and bright in the Eastern
sky.
The Role: It acted as the
ultimate herald of the dawn sector. Because the Earth's precessional shift back
in 1468 BCE (astronomical year) pulled the Pleiades much closer to the
celestial equator, its ascent in the East directly marked the celestial highway
where the Sun would emerge 80 minutes later. It anchored the East/Birth
quadrant.
2. The Western Anchor: Cygnus (The Swan)
The Position: Opposing the Pleiades, the brilliant cross of
Cynus was diving nose-first down toward the Western horizon.
The Role: As a massive
constellation sitting right in the thick lane of the Milky Way, its descent
marked the West/Death quadrant (the Amentet), where the stars go to die beneath
the horizon, balancing the rise of the Pleiades.
3. The Northern Anchor: Cassiopeia
The Position: While Draco and the Little Dipper sat right
at the bottom/center of the meridian, the unmistakable "W" or "M
shape of Cassiopeia sat soaring beautifully high above the North pole in the
upper northern sky.
The Role: It framed the top end of the vertical
meridian axis. If a priest looked up past Kappa Draconis, Cassiopeia was the
crown anchoring the top of the Northern/Imperishable quadrant.
4. The Southern Anchor: Scorpius (Serket)
The Position: On the exact opposite side of the sky from
Cassiopeia, the tail and heart of Scorpius (Antares) were skim-flashing along
the South-Western horizon.
The Role: In ancient Egyptian astronomy, the scorpion
goddess Serket guarded the breathing of the deceased. Positioned at the lowest
point of the southern sky during dawn, it anchored the Southern/Underworld
quadrant.
The Macro-Symmetry of the
New Kingdom
The priests were validating
a tetra-cardinal cosmic template. By verifying that Cassiopeia was high,
Scorpius was low, the Pleiades were rising in the East and Cygnus was setting
in the West, they proved that the entire "Stretching of the Cord"
ritual was happening at the exact moment of perfect universal equilibrium.
To see exactly how balanced
the universe looked to the Egyptian priests at 4:40 AM local solar time on
October 9, 1468 BCE (astronomical year) in Thebes, it is necessary to examine
the precise mathematical altitude and azimuth coordinates of these four
macro-anchors.
At this exact moment, the
sky was framed by an astonishing geometric symmetry, with the four
constellations perfectly partitioning the dome of heaven into four clean quadrants.
Horizon Coordinates of the 4
Macro-Anchors (4:40 AM)
Cassiopeia (Schedar): Altitude 39.5-degrees, Azimuth 335.6-degrees
(North-Northwest), Northern Crown: Soaring high over the pole.
The Pleides (Alcyone /
Tau): Altitude 43.7-degrees, Azimuth 242.1-degrees
(West-Southwest), Western Descent: Cruising downward past the meridian.
Cygnus (Deneb): Altitude 12.5-degrees, Azimuth 301.2-degrees
(Northwest), Northwestern Diver: Plummeting toward the horizon.
Scorpius (Antares): Altitude 7.8-degrees, 114.9-degrees (East
Southeast), Eastern Ascent: Emerging to guard the dawn.
How the Priests Sighted the
Quadrants
The alignment of these four
massive constellations created a visual bounding box for the Imperishable Stars
at the center:
1. The High Axis (40 to 44-degrees): Cassiopeia dominated the upper northern sky,
while The Pleiades dominated the upper western sky. They formed a high
celestial ceiling.
2. The Low Axis (8 to 12-degrees): Scorpius and
Cygnus hugged the opposing horizons like two low anchors stabilizing the edges
of the flat horizon plane.
The Finished Template
By reading this macro-grid,
the "mety n sa" (astronomer-priest) saw a giant, interlocking
machine. The low setting Cygnus locked gears with the low rising of Scorpius,
while Cassiopeia and the Pleiades held up the vault of the night sky. At 4:40
AM, everything was perfectly balanced for the "Stretching of the
Cord".
One may link the four
macro-quadrants to Thuban, Kappa Draconis, Kochab and Polaris. In doing so, it
unlocks the grandest cycle in all astronomy: the Precession of the Equinoxes.
The interlocking quadrant
system acts as a giant cosmic dial that tracks the changing identity of the
Earth's pole star over a massive 25,772-year cycle. The four quadrants act as
the structural "foundations" that hold up the changing pivot points
of human history.
1. The Anchors (The Quadrants) Stay Fixed, the
Center Shifts
Think of Cassiopeia, the
Pleiades, Cygnus and Scorpius as four massive pillars driven into the horizon
of the Earth. No matter how much the Earth's axis wobble over an extend time
period, these major constellations remain locked in their celestial sectors.
However, because the Earth's
axis is tilting and shifting relative to these pillars, the true pivot center
of the sky slowly migrates inside the northern quadrant. The four pole stars
mark different hours on this grand clock.
2. Thuban:
The Old Kingdom Anchor
The Era: circa 2800 BCE (The
Age of the Great Pyramids)
During this era, the
northern quadrant was anchored flawlessly by Thuban. When Cassiopeia rose to
its highest point on the meridian, it pointed straight down through Thuban to
mark True North.
3. Kappa Draconis: The New Kingdom Pivot (The Target Date: 1468
BCE (astronomical year)
The Era: circa 1500 BCE (The
Age of Hatshepsut and Thutmose III).
At 5:07 AM on October 9,
Kappa Draconis sat at 359.9-degrees Azimuth--the exact center. At this precise
moment, Kappa Draconis was the "bridge" star. It held the center of
the quadrant, balancing the dying memory of Thuban on its right and the rising
future Kochab on its left.
4. Kochab (Beta Ursae Minoris): The Later Guard
The Era: circa 1100 to 400
BCE (The Late Period of Egypt / Classical Greece).
As the pole continued its
slow migration across the northern sky, it left the constellation Draco
entirely and entered Ursa Minor (the Little Dipper), targeting Kochab.
5. Polaris (Alpha Ursae Minoris): The Modern Crown
The Era: 500 CE to Present (Our modern world)
Today, the pole has
travelled to the opposite end of the Little Dipper's tail, sitting almost
perfectly on Polaris. Because of this 3,500-year shift since 1468 BCE, the
entire macro-grid looks distorted to us today. If you look at Polaris tonight,
Cassiopeia and the Pleiades sit in completely different angular relationships
to the pole than they did for the priests at Thebes.
The Ultimate
Archaeoastronomy Synthesis
To the ancient Egyptian
mind, this was the ultimate mystery of "Heh" (infinity). They noticed that over
deep time, the "Imperishable Stars" slowly shifted their positions
relative to the ground.
By mapping the four
macro-quadrants (Cassiopeia, Cygnus, Scorpius and Pleiades), they built a
geometric framework that was immune to precession. A temple aligned perfectly
to the 90-degree cross-axis of those quadrants would remain structurally true
to the Earth's horizons forever, even as Thuban passed the crown of North to
Kappa Draconis, then to Kochab, and finally to our modern Polaris.
The interlocking geometric
relationship between the "W" of Cassiopeia and the Little Dipper
(Ursa Minor) provides a functional explanation for how ancient observers
navigated the shifting polar sky. To the naked eye, these two star groups act as
a synchronized, dual-sided mirror. When
they are viewed through the lens of precession, their specific shapes reveal a
brilliant architectural purpose.
1. The 180-Degree Cosmic Scale
Cassiopeia and the Little
Dipper sit exactly opposite each other across the pivot point of the NCP.
When the Little Dipper is
low on the horizon, Cassiopeia's "W" is soaring upside down at the
top of the sky.
When the Little Dipper rises
high, Cassiopeia sinks low.
Because they are locked in
this eternal seesaw, their shapes work together like visual calipers or a
carpenter's square to frame the changing center.
2. The Shape Link: Outer Track vs. Inner Track
The link between the shapes
comes down to angular tracking:
The Little Dipper is an
"Inner Track" Star Group: It clusters tightly around the pole. In
1468 BCE (astonomical year) both Kochab and Pherkad spun in a very small
circle. They functioned like the short hour-hand of a clock.
Cassiopeia is an "Outer
Track" Star Group: The "W" sits further out from the center. It
functions like a massive, wide-set sightline.
In ancient Thebes (1468
BCE), the deeper "V" of Cassiopeia pointed to the bowl (or should one
say the "W" in the bowl of the Little Dipper. Today, it points to the
polestar Polaris.
The Visual Pouring Metaphor
In ancient times, the
relationship between these shapes is often described as a fluid balance: the
open bowl of the Little Dipper and the open peaks of Cassiopeia's "W"
are angles such that they appear to endlessly pour their stars into one another
as they rotate.
The 7:00 PM to 8:30 PM
Timeline of the Verticality of the Milky Way
The four stars and one node
(the unmarked NCP) form a perfect geometric mirror to the vertical Milky
Way. When the Milky Way stands straight
up, these northern elements act as the hidden gears that lock the entire sky
into place.
Here is the exact geometric
dance in the North and South.
1. The Right-Angle Intersect
(The 7:00 PM Geometry)
The Milky Way spans from the
Southwest to the Northeast between 7:00 PM and 8:30 PM.
If the priest looked away
from the Milky Way and turned directly North at that exact hour, the four stars
and one node create a horizontal alignment that sits perpendicular (90 degrees)
to the Milky Way's verticality.
The Node (NCP): Earth's axis points right at this blank spot
in Draco.
The 4-Star Line: The rotation of the Earth has swung Kochab
and Pherkad to the far right (East) of the node, while Thuban and Kappa
Draconis have swung to the far (West). They form a perfectly level, horizontal
line slicing through the North Celestial Pole. The Milky Way meets the
horizontal northern star-line at a clean, cross-section.
2. The Celestial Loom: Spine v Axle
This geometric relationship
between the vertical galaxy and the circumpolar stars was the ultimate symbol
of cosmic balance (Ma'at).
The Milky Way (The Moving
Spine)
Represented the fluid,
changing body of the goddess Nut. It was vertical, dynamic as well as connected
the realm of the living with the dead on the horizon.
The Northern Stars (The
Unmoving Axle
The four stars spinning
perfectly around the central node (the pivot-point of creation) represented
eternal, unshakeable law.
When the Milky Way reached
its vertical peak, it meant the fluid "river" of heaven was
mathematically squared with the rigid permanent northern "anchor" of
the universe.
3. The 12-Hour Polar Flip (The 6:00 AM Hand-Off)
As the night progressed to
6:00 AM, the geometry completely inverted. The Milky Way flattened out and set.
It disappeared from view.
Simultaneously, the four
stars rotated exactly 90 degrees around the northern node. The horizontal line
they held at dusk flipped into a perfectly vertical plum line at dawn. This
allowed the priests to drop their "merket" lines and map the true
geographic North-South axis onto the temple floor.
The Position of the Big
Dipper
The position of the Big
Dipper (Meshetyu) can be precisely determined. It swings a large
counter-clockwise circle around the NCP (the node), acting as a massive comic
clock face over a 24-hour cycle.
1. At 7:00 PM (Dusk / The Vertical Milky Way
Window
When the Milky Way reached
its peak vertical orientation in the south, the Big Dipper was positioned
extremely low, scraping the Northern Horizon in its lowest culmination (its
lowest point in the sky).
Orientation: The constellation was oriented horizontally.
It looked like a wagon resting flat on the ground.
Spatial Position: The bowl of the dipper was pointing to the
North-Northwest (NNW), while its curved handle trailed backward toward the
(NW).
The Pointer Stars: The two end stars of the bowl (Dubhe and
Merak) pointed straight upward from the horizon aiming directly at the unmarked
NCP and the horizontal alignment of Kochab and Thuban.
2. At 6:00 AM (Dawn / The 4-Stars Vertical Line
Window
Exactly eleven hours later,
as dawn began to break and the four stars (Kochab, Pherkad, Thuban and Kappa
Draconis) locked into the perfect vertical alignment, the Big Dipper had
rotated nearly 165 degrees up the eastern side of the sky.
Orientaion: The constellation was now standing completely
vertical, balancing on its handle.
Spatial Position: It hung
high in the North-Northeast (NNE) sky.
The Pointer Stars: The bowl was now at the very top of the
constellation, pointing due West directly across the vertical meridian line
toward the 4-star alignment.
The Symmetrical Dance: At 7:00 Pm, when the body of the goddess Nut
(The Milky Way) stood vertical in the south, the Big Dipper was suppressed,
lying flat and low on the northern horizon.
The Ritual Pivot: By 8:30 PM, as the Milky Way vanished, the
Big Dipper stood completely upright in the NNE sky. Its vertical shape mirrored
the geometric form of an Egyptian adze--the tool used in the sacred
"Opening of the Mouth" funerary ritual to grant eternal life to the
decease Pharaoh.
