Let us look at another doodle by a stone swinging Irishman – Kerbstone 52 from Knowth, Ireland.

The Knowth mound has a diameter 275 feet and has 127 kerbstones surrounding the base perimeter of approximately 866 feet. This circumference brings to mind the diameter of the Sun at 864,000 miles. Because we are discussing a circular mound the idea of pi comes to mind. 127 x pi equals 399. The diameter of the Moon is 2160 and that of the Sun is 864336 and this gives us the ratio of 1:400 regardless of the units used.

So, now we begin a study of the petroglyph found on Kerbstone 52 as sketched in the figure. Dr. Philip Stooke suggests in his article that this drawing is of the phases of the moon as it exhibits several images we can easily associate with its changing appearance. However, even he admitted that these symbols really have little in common with the actual observed appearance of the Moon throughout a month.

He noted that there are 29 phases depicted above and below the center up-down line. There are four circles marked T, three circles marked B, one up-side down crescent marked D, two left opening crescents or C’s marked L, 17 left opening C’s marked U that lie underneath in a straight line, followed by crescent R which is removed from the group and the cycle ends with the crescent marked M. A sum of these reveals there are indeed 29 symbols encircling the up-down line. There are two crescents below the circles in the middle. Not all sketches depict these two.

At this point most people conclude the artist was not very gifted or a lousy observer and they move on. However, we shall be a little more determined than most so that we might prove the translation of the previous stone was not wildly co-incidental.

Here we start by counting all the symbols. Because the one C is removed from the rest there is a tendency to get only 28. We see 28 x 2 = 56. This number 56 appears at Stonehenge. There are 56 Aubrey holes surrounding Stonehenge which are unexplained. It was the number found last in the previous kerbstone study.

If the crescent marked R is placed with the 28 we obtain 1 plus 28 or 128 which is one more than the number of kerbstones. 128 x pi = 402 which reflects the ratio between the diameter of the Sun and Moon and the ratio of their distances from Earth, both of which is 400 to 1.

If the crescents are counted as 29 and the two below are considered, then we have 29.2. Twice this number is 58.4. The distance earth travels in a year is 58.4 million miles.

At the center is a spiral symbol. This can be translated to mean cycles, repetition, turning or the ecliptic. So perhaps we are looking for cycles involving the Moon, Sun and Earth.

The up-down line has 16 cycles or 16 up and 16 down for 32. The square root of 32 is 5.65 which repeats the 56.

Add the 16 up and 16 down to the 28 crescents and obtain 60 for minutes and seconds. Now we might notice that the 22 crescents surrounding the line plus the two C in the middle create 24 as in hours in a day? These are both cyclic numbers.

We look again at the image and see the circles may also represent the Sun not only the Moon. We count 4 T circles plus 3 B circles and the 2 crescents below the circles. 4 3 2? The radius of the Sun is 432,000 miles or multiply by 2 and obtain 864, the diameter of the Sun at 864,000 miles.

Notice those two crescents below the 7 circles which are back to back. 1 and 1 as in 11. Note that 11 seems to have special meaning in two ways. The first is symbolic suggesting One God. 11 x 11 = 121, 111 x 111 = 12321 and 1111 x 1111 = 1234321 which is rather unique feature of 1 or 11, and might indeed impress someone with its holiness. It may simply mean the sum of 5 + 6 = 11.

If we multiply the 11 by the 7 circles above we obtain 77. As 7.7 it is the square of 2.77.

Dr. Stooke noted the 29 correlates with the number of days in a lunar month. Here is the thing. The lunar month is not a fixed number like the Earth’s year. It varies. The longest period of time between full moons is about 29.72 days. On the average today it is 29.53 days.

So here is the trick. Start counting these 29 symbols at the left circle T moving clockwise and upon completing the circle pause and then recount the 7 circles to obtain: 29 pause 7 or the 29.7 days of the longest average month. Or proceed in this manner. Begin at the same spot counting clockwise 29 pause, count 4 T pause, and conclude with 3 B circles. So that now we obtain 29.43 or one of the shortest lunar months.

Or find the Sidereal Lunar month by counting all 29 symbols and then add the 32 (16 up/downs) to create 29.32 but this is off by two days. The actual value is 27.32 which we can obtain if we subtract the 2 upper middle crescents.

The 29.7 is a unique number in that if it is read in reverse it reads 7.92 or the diameter of the Earth 7920 miles. The diameter can also be obtained by noting the 7 circles, add the 2 middle crescents for 9 and then the 22 remaining crescents for 7922.

There are 7 circles in all. What is the probability each circle represents a day or a 7 day week? If they used a seven day week, would we not find 52 weeks represented?

Begin at those 2 middle crescents, add the seven circles and then add the 22 remaining crescents to obtain 2 7 22 or 2722 which is the square of 52.17 or the weeks in a year.

This 2.722 nearly gives us the 2.77 we have already discussed.

The diameter of the moon is easily found. There are 2 L’s and 16 “cycles” on the up-down line which gives us 2160 mile diameter. Or from the reverse direction R and M followed by the 16 cycles gives the same 216. The 16 ups and downs also reminds us the earth travels 1.6 million miles in a day. This idea is further illustrated by the left end of the line which curls round like the earth turning in a day.

We may further suggest that the up-down line describes something that goes up and comes down because of gravity. The sum of 16 + 16 = 32 and that reminds us of 32.17 ft/sec² of gravity. Which then makes us look at those 17 U’s beneath the line to create 32.17.

The 1 R crescent followed by the 17 U’s creates 117 which is 2 x 58.5. This brings to mind earth’s circumferential orbit each year of 584 million miles found previously.

The 17 U’s are significant. They may represent the 173 AU that light travels in a day or the 17 minutes it takes light to traverse the diameter of Earth’s orbit. This makes the up-down line a symbol of light traveling which, ironically, is pretty much how we symbolize light traveling today.

So, this is one very complicated mathematical message after all! But is it remotely possible these stone wielding cave men knew anything of science?

Recall that the Pyramids are considered to be some 4800 years old and that many people have found values which represent Earth and Solar System measurements designed into its structure. Knowth is some 500 to 700 years older than the pyramids which is a reasonable period of time to develop the engineering skills to step from building round monuments to monstrous pyramidal monuments.

Your report is very good, however it is difficult to see the exact tool used to establish the distances. By understanding the 29.6 day cycle of the lunar month an early navigator could use the mid day sun and location of the moon to predict his longitude position on earth.

It seems the Egyptians also determined these values. Perhaps their source of information was the same. Perhaps the artist did not need to know how to measure them just what these values were so they could be recorded for posterity or worship. In the same way I know what they are but could never duplicate them.

From reading some of your work, I know your knowledge of navigation far out distances mine. That they can be used to determine longitude is interesting.
