This subject, of Irish megalithsStructures built out of large little-altered stones in the new stone age or neolithic between 5,000-2,500 (bronze age), in the pursuit of astronomical knowledge. has been on hold since perhaps 2020 due to other work.
The Metrology
At that time I was working on Sacred Geometries in Ancient Goddess Cultures (Heath, 2022) and using a new, very-small unit of 3/100 (0.03) feet, found to be in practical use in Britain in a circle called Seascale (in Cumbria, see pages 109-113, 138-140 of Sacred Geometries: Language of the Angels (2018) : namely the su-shi, one sixtieth part of the historical Assyrian double foot of 1.8 feet (0.03 feet), and 30 in the foot of 0.9 feet.
The moon’s nodal periodUsually referring to the backwards motion of the lunar orbit's nodes over 6800 days (18.618 years), leading to eclipse cycles like the Saros. is exactly 6800 days and dividing 6800 by 100 (6.8 feet) then multiplying by 3 = 204 feet. In this it is the prime number 17 that is being transformed into 4 x 17 = 68. Alexander Thom’s megalithic yardAny unit of length 2.7-2.73 feet long, after Alexander Thom discovered 2.72 ft and 2.722 ft as units within the geometry within the megalithic monuments of Britain and Brittany. (MY) was his of 2.72 feet and megalithic rod (MR) was the “step” of 2.5 x 2.72 = 6.8 feet. Three megalithic rods equal 20.4 feet, one tenth of 204 feet. This reduction of 6800, to a length of 204 feet, was shown visually as figure 6.3, repeated below.
figure 1. relating 6800 day-feet to 204 feet fig.6.3 of Heath 2018
It is then obvious that a length of 204 feet between significant points within a monument could be indicative of an original counted length, in feet, using megalithic rods with the prime number 17 within 272 = 16 x 17.
The su-shi is then becomes the technical day length of a single day, of 3/100 day-feet or 0.36 inches, one hundred of which equals 36 inches (a yard of three feet), 3 MR equaling 20.4 feet, one tenth of 204 feet. I will make a link another post about 20.4 and add 204 to the tag cloud.
The use of Dolmen to initiate counts.
In CarnacAn extensive megalithic complex in southern Brittany, western France, predating the British megalithic. I found a clear example of this in Crucuno village, where the Dolmen now abbutted a stone house stars a 47 lunar month could to the Crucuno rectangle, coded to 27 feet per lunar month, each day then worth 32/35 feet, the Iberian foot (2018, 237-8), enabling days to be measured within months. The count of 47 lunar months occurs just after 4 eclipse years (of 346.62 days), the smallest eclipse cycle that gives similar eclipses.
The megalithic in Wales, related to Ireland as a portal design, built at least one dolmen (Pentre Ifan) about 20,400 (i.e. 6800 x 3 feet away) feet from another to the north, this then facing at right angles, to the west. But here at KilClooney, there is a south to north alignment of a smaller enclosure leading to KilClooney, see figure below .
Figure 2 Kilclooney dolmen and southern enclosure aligned North and showing summer solsticeThe extreme points of sunrise and sunset in the year. In midwinter the sun is to the south of the celestial equator (the reverse in the southern hemisphere) and in midsummer the sun is north of that equator, which is above the geographical Equator). sunrise in red, and northerly maximum standstill of the moonrise.
The distance between the flat ended enclosure stone (to northwest) and the central southernmost tip of Kilclooney is a length (on plan) of 204 feet, thus relevant to the nodal cycle between maximum moons of 6800 days, but now a length of 10 megalithic rods of 20.4 feet.
If one leaves the units of feet and uses inches then 204 x 12 =2448 which, divided by 0.36, equals 6800 (day-sushi of the nodal period). As with Crucuno, one has two types of unit, in this case megalithic rod and Assyrian foot, operating at a megalithic site concerning an eclipse or nodal cycle.
