Test #5 North South East and West
Sabtu, 12 Maret 2016 by Alfanet Fx
Celestial phenomena form the basis for most cardinal and ordinal directional systems and the same was true anciently.
Fact #1. In temperate and tropical latitudes (south of the Arctic Circle, north of the Antarctic Circle), the sun rises in the east and sets in the west. On a flat horizon, sunrise will be due east and sunset due west twice a year, on the vernal equinox (near March 21) and the autumnal equinox (near September 21). The site of Dzibilchaltun in Yucatan is justifiably famous with tourists partly because of spectacular site alignments on equinox sunrise.

This is the same structure on vernal equinox about 30 minutes after sunrise.

Even more renowned among tourists is the serpent of light that appears on the steps of the Temple of Kukulcan (El Castillo) at Chichen Itza on the afternoon of each equinox.

Fact #2. The earth's spin axis is tilted 23.5 degrees from the plane of the ecliptic, the hypothetical plane that intersects both the earth and the sun. This tilt causes the seasons as days in the northern hemisphere lengthen toward summer solstice (near June 21) and shorten toward winter solstice (near December 21).

At the equator on a flat horizon, the sun will rise on the summer solstice at a point 23.5 degrees north of due east. On the winter solstice that point will be 23.5 degrees south of due east. So, at the equator throughout one solar year, the sunrise point will vary across 47 degrees of a 360 degree arc, with that variation centered on due east. As one moves north or south of the equator, variation in solstitial sunrise points increases according to the formula 23.5/cosine(latitude). So, for example, the solstitial variation between sunrise points at Guatemala City (15.5 degrees north latitude) is 48.77 degrees on a flat horizon, slightly more than at the equator. The solstitial variation between sunrise points at Mexico City (19 degrees north latitude) is 49.70 degrees on a flat horizon. Mexico City (Teotihuacan) is about the northern extreme of New World locations that could plausibly be referenced in the Book of Mormon text. So, when the Nephites observed sunrise or sunset, they were looking at points on the horizon within 24.85 degrees of due east or due west. As with the equinoxes, solstice sunrise points were important in ancient architectural layouts. This, for example, is the entrance to the famous Temple of Karnak in Egypt on the winter solstice sunrise.

Moonrise and moonset points follow a more complex but ultimately similar pattern. The new moon rises due east and sets due west on the spring and fall equinoxes, just as the sun does. The full moon does the same. The waxing moon rises due east and sets due west on the summer and winter solstices, which is opposite the sun's behavior. The waning moon does the same. As the moon goes through its phases, it will rise and set at points on the horizon that vary (at the equator) by the 23.5 degrees of the earth's tilt + the 5 degrees of the moon's own tilt. Like sunrise and sunset points, the amount of moonrise/set variation north and south of due east/west increases as one moves from the equator to higher latitudes. This graph from Paul Middents of the Battle Point Astronomical Association shows lunar rise/set point variation on the horizon relative to solar rise/set point variation across the 18.6 years of a Draconic Cycle.

| Variation in moonrise points on the horizon relative to sunrise points |
As the graph shows, some years the variation in moonrise points will be up to 5 degrees smaller than the variation in corresponding sunrise points. Some years the variation in moonrise points will be up to 5 degrees greater. Like the sun, the apparent movement of the moon will always center on due east and due west.
Venus, the evening and morning star, exhibits similar predictable behavior in the sky rising and setting on the horizon at points in between the solar and lunar maximums. The apparent motion of Venus is affected by its sidereal period (225 days), its synodic period (583.9 days), the tilt of its axis (2.7 degrees away from the plane of the ecliptic) and its interaction with earth's sidereal period (365.256 solar days). The ancient Assyrians were careful observers of the planet's movements as shown in the Venus Tablet of Ammisaduqa on display in the British Museum. This 7th century B.C. copy of a 17th century B.C. text was in the library at Nineveh.

The Maya were even more precise in many of their Venus observations. The famous Dresden Codex calculates Venus cycles to within 1/100th of a day.

In his outstanding new book
Izapa Sacred Space: Sculpture Calendar Codex, 2nd Edition, 2013, V. Garth Norman shows how Izapa was laid out with clear site alignments to lunar, Venus and solar azimuths on the majestic horizon which includes 4,220 meter high Tajumulco, the highest mountain in Central America

Throughout their various cycles and periods, the sun, the moon and the planet Venus all rise at azimuths centered on true east and set at azimuths centered on true west. The sun shows the smallest variation in maximum (solstitial) rise and set points on the horizon because it is only affected by the 23.5 degree tilt of the earth's spin axis. Venus shows slightly more variation in its maximum rise and set points on the horizon because it is affected by the 23.5 degrees of the earth's tilt + the additional 2.7 degrees of its own tilt. The moon, across the 18.6 years of a Draconic cycle, shows the most variation in its maximum rise and set points because it is affected by the 23.5 degrees of the earth's tilt + the additional 5 degrees of its own tilt. Ancient American skywatchers followed these patterns with great interest and based their calendars on immutable celestial phenomena.
Fact #3. The earth's rotational axis slowly changes orientation, moving in a circle that requires about 25,770 years to complete. This phenomenon, called axial precession, is illustrated in the graphic below.
 |
| Earth's Precession |
Because of the earth's rotation, the sky at night seems to wheel in a huge circle around the pole star. This time lapsed image captures the essence of apparent star motion, noted by ancient sky watchers around the globe.
 |
| Stars in apparent rotation around the pole star |
Today, the pole star in the northern hemisphere is Polaris, commonly called the north star. Because of the earth's axial precession, the faint star Gamma Cephei will replace Polaris as the pole star about 1,000 years from now. In 2,000 B.C., the pole star was the faint star Thuban in the constellation Draco. This chart shows the way the pole star changes through the 25,770 years of earth's axial precession cycle.

Sometimes in past ages the celestial pole was simply a void with no visible star at the center of the wheel. Nonetheless, ancient mariners and astronomers in the northern hemisphere oriented to this pole as an unerring indicator of true north at right angles with the eastern sunrise and western sunset. The Southern Hemisphere also has its celestial pole. The two stars forming the long leg of the famous Southern Cross point to the south celestial pole. This important navigational aid is emblazoned on the flag of Australia.
These celestial phenomena gave rise to systems of cardinal directionality broadly similar to the one we use today. Biblical authors, for example, called their cardinal points zaphon, negev, kedem and yam, words derived largely from their Levantine geography.

| Biblical Cardinal Directions |
The association of east with sunrise is well attested in the Biblical text. Numbers 2:3, Joshua 12:1, Isaiah 45:6, Isaiah 59:19,Ezekiel 8:16,
In the New World scribal tradition, east was also the direction of sunrise. See "The Defeat of Cabracan" phrases 4, 14 in Popol Vuh Electronic Library, Allen J. Christenson translator and editor, Provo, UT: Brigham Young University, 2007. See the blog article "Water Fight on the River - Round Ten" for a number of other indications the ancient Mesoamericans knew and used an astral-based system of cardinal directionality similar to our own.
The Aztec Calendar Stone served many purposes and illustrated many cosmological, chronological and geographic concepts among the ancient Nahuatl of central Mexico. Among other things, the Aztec Calendar Stone was a classic compass rose, dividing space into equal quadrants centered on the cardinal points we know today as north, south, east and west with ordinal points NE, SE, SW and NW.

We commissioned Mexican graphics artist Fernando Vazquez to create a compass rose based on the Aztec Calendar Stone with cardinal, ordinal and intermediate points indicated. We will use this graphic to help us keep everything straight as we wander through the Book of Mormon text examining all occurrences of the words "north," "south," "east," and "west" with variants.

NorthTerms derived from the root "north" appear 83 times in the text:
- north 36 instances, 33 in a specific geographic context that can be mapped
- northward 45 instances, all in a specific context
- northern 1 instance, in a context we can map
- northernmost 1 instance, in a discrete context
Netting out duplicates, we have 39 from and to location pairs where we can calculate the azimuth of the vector between them. Azimuths could range from northwest (315 degrees) to northeast (45 degrees) and still be in the north quadrant. We plot all 39 vectors and calculate variance from true north. As with all images on this blog, click to enlarge.
 |
| Analysis of All Occurrences of the Term "North" with Variants |
A summary of our results:
- No variance exceeds 45 degrees which means all azimuths fall within the north quadrant. Our correlations conform to the text 100%.
- The term "north" trends much more strongly toward true north than the term "northward," precisely as we would expect given the common usage of those terms in English.
- "Northward" generally means in a northwest direction which is not surprising given the lay of the land and the flow of the rivers in southern Mesoamerica.

SouthTerms derived from the root "south" appear 57 times in the text:
- south 36 instances, 34 in a specific geographic context that can be mapped
- southward 20 instances, all in a specific context
- south-southeast 1 instance, in a discrete context
Netting out duplicates, we have 36 from and to location pairs where we can calculate the azimuth of the vector between them. Azimuths could range from southwest (225 degrees) to southeast (135 degrees) and still be in the south quadrant. We plot all 36 vectors and calculate variance from true south, or in the case of the term south-southeast 1 Nephi 16:13, variance from true south-southeast (157.5 degrees).
 |
| Analysis of All Occurrences of the Term "South" with Variants |
A summary of our results:
- No variance exceeds 45 degrees which means all azimuths fall within the south quadrant. Our correlations conform to the text 100%.
- The term "south" trends much more strongly toward true south than the term "southward," precisely as we would expect given the common usage of those terms in English.
- "Southward" always means in a southeast direction which is not surprising given the lay of the land and the flow of the rivers in southern Mesoamerica.

 |
| Analysis of All Occurrences of the Term "East" with Variants |
A summary of our results:
- No variance exceeds 45 degrees which means all azimuths fall within the east quadrant. Our correlations conform to the text 100%.
- Less variance occurs with east directions than with either north or south directions. This is due to the large number of east vectors that originate or terminate on the seacoast or river Sidon.
- Our sample size for the term "eastward" is too small to support meaningful conclusions.

Azimuths could range from northwest (315 degrees) to southwest (225 degrees) and still be in the west quadrant. The phrase "west and north" occurs once in association with the phrase "on the west, and on the north" Alma 2:36-37. That variance we calculate from true northwest (315 degrees).

A summary of our results:
- No variance exceeds 45 degrees which means all azimuths fall within the west quadrant. Our correlations conform to the text 100%.
- Less variance occurs with west directions than with north, south or east directions. This is due to the very large number of west vectors that originate or terminate on the seacoast or river Sidon.

ConclusionWe have now analyzed all 232 occurrences of the terms "north," "south," "east," and "west" with variants in the text. We have identified 133 discrete from and to locations in both the Old World and the New where we can map a vector between them and calculate a directional azimuth. We have compared these 133 directional azimuths against the cardinal points of a traditional compass rose and calculated variance. In all 133 cases, the variance is less than 45 degrees which means our map fits the text precisely without discrepancy. We submit any viable Book of Mormon geographic correlation should pass this test.
