In working at Lochmariaquer, an early discovery has returned in the form of a near-Pythagorean triangle with sides 18, 19 and 6. But first, how did this work on cosmic N:N+1 triangles get started?
Robin's earliest work couched the Lunation Triangle within three right angled triangles that could easily be constructred yet describe the number of lunar months and orbits in the solar year and the length of the eclipse year, using the number series 11, 12, 13, 14 to form N:N+1 triangles. Each triangle could then have an intermediate hypotenuse set at the 3:2 point of the shortest side, so as to form the eclipse year (11.37 mean solar months) and solar year (12.368 in lunar months), plus the orbits in a solar year (13.368 orbits). The 12 length is the lunar months in a lunar year but also the mean solar months in a solar year and the length 13 is the length of another type of lunar year (in lunar months) and the number of orbits in a 12 month lunar year. A bit of a mouthful so I have made a diagram of them below in figure 1.
Figure 1 Robin Heath's original set of three right angled triangles that exploit the 3:2 points to make intermediate hypotenuses so as to achieve numerically accurate time lengths in units of lunar or solar months and lunar orbits.
It came to me that the 18-19-6 triple was interesting in that the amount by which it deviated from the Pythagorean rule (whole numbers for all three sides) causes the 18 side to be 18.027 long, so that the triangle is then still a right angled triangle. This number (18.027) was familiar to me as being the length in years of the Saros eclipse period, of 18.030 solar years. It seemed wonderful, as if nature was somehow shaping reality to suit a near-Pythagorean triangle. It was also interesting because the Saros is 19 eclipse years, by definition, so the base of the triangle can be metrological shifted to units in the ratio solar year to eclipse year, so that both the longer sides are then, each 19 (different) units long, eclipse years on the base and solar years on the hypotenuse.
Figure 2 The near Pythagorean triple 6-18-19 can have the 18 side equal 18.027 so as to restore the triangle as right angles. This length is very close to the Saros period in solar years, since 19 eclipse years and 223 lunar months long are 18.030 solar years long.
This triangle soon became "eclipsed" by new progress, when Robin and I, one Christmas (1993 or 4), found the single unit that divides into both the eclipse and solar years, revealing that the moon's nodal period, the solar year and the eclipse year are normalised to the tropical day, through be rate the eclipse nodes move per day.
The number of days it takes for the lunar nodes to move one DAY, in angle, (the angle the sun moves in a single solar day) is 18.618 days. This makes the eclipse year equal 18.618 x 18.618 days, the solar year 19.618 x 18.618 days, the difference between the years then being 18.618 days and the nodal period being 18.618 solar years and 19.618 eclipse years long. (This was further explored in Robin Heath's Wooden Book called Sun, Moon and Earth)
Out of this relationship comes a VERY important triangle found at Le Menec and Mane Lud/Locmariaquer, with longer sides 18.618 and 19.618 and third side 6.18.
Figure 3 The Node Day of 18.618 days provides a normalising unit for the Solar and Eclipse year, meaning that 18.618 days equals the one difference between the two types of year.
Obviously, this is just larger than the 18-19-6 triangle mentioned above and its sharp angle is 18.36 instead of 18.40 degrees.
The third triangle that is similar is that produced by the diagonal of a triple square and this similarity was understood by Robin through his work on that geometry known through Alexander Thom as a Type B flattened circle - a circle whose perimeter has been reduced in length through using arcs or variable radius.
Figure 4 How the geometry of Le Manio could be linked to the triple square and the flattened Type B ring design. The green dotted lines show the Vesica of overlapping circles, to be found in the design which would then be two eclipse years long in day-inch counting.
Robin noted the proximity to an 18.618:19.618 triangle, implicit within these designs, though it is actually the angle of the diagonal of a triple square, which is 18.43 degrees and only 1 1/2 minutes of a degree different to the angle of an 18.027:19:6 triangle. In Carnac, a study group in Carnac area called AAK published site plans in which multiple squares were found to define many monuments and in the
