- Story of Three Similar Triangles
first published on 24 May 2012, Figure 1 Robin Heath’s original set of three right angled triangles that exploited 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. Interpreting Lochmariaquer in 2012, an early discovery was of a near-Pythagorean triangle … Continue reading “Buildings and Artifacts” - Working with Prime Numbers
Wikipedia diagram by David Eppstein : This is an updated text from 2002, called “Finding the Perfect Ruler” Any number with limited “significant digits” can be and should be expressed as a product of positive and negative powers of the prime numbers that make it up. For example, 23.413 and 234130 can both be expressed as … Continue reading “Working with Prime Numbers” - Counting Days and Lunar Months
Megalithic astronomy achieved far more than modern studies of their astronomy have thought possible. The role of the megalithic in seeding the later religious ideas, of subsequent civilizations, has therefore caused ancient religions to be seen as having no objective basis, and to be considered works of human imagination alone. To correct for this wrong … Continue reading “Counting Days and Lunar Months” - Use of foot ratios in Megalithic Astronomy
The ratios of ancient metrologyThe application of units of length to problems of measurement, design, comparison or calculation. emerged from the Megalithic innovations of count&compare: counting time as length and comparing lengths as the longest sides of right triangles. To compare two lengths in this way, one can take a longer rope length and lay … Continue reading “Use of foot ratios in Megalithic Astronomy” - Models of Time within Henges and Circles
image: composite, see figure 1 below Presenting important information clearly often requires the context be shown, within a greater whole. Map makers often provide an inset, showing a larger map at a smaller scaling (as below, of South America) within a detailed map (of Southern Mexico). Megalithic astronomy generated maps of time periods, using lines, … Continue reading “Models of Time within Henges and Circles” - Megalithic Measurement of Jupiter’s Synodic Period

The word Alignment is used in France to describe its stone rows. Their interpretation has been various, from being an army turned to stone (a local myth) to their use, like graph paper, for extrapolation of values (Thom). That stone rows were alignmentsIn general, to the sun and moon on the horizon, rising in the … Continue reading “Erdeven Alignment’s counting of MetonicGreek: The continuous 19 year recurrence of the moon's phase and location amongst the stars. and SarosThe dominant eclipse period of 223 lunar months after which a near identical lunar or solar eclipse will occur.

The Phaistos Disk was discovered in 1908 in chamber 8 of the northeast wing of the “Old Palace” (pre-1700 BCE) as per above diagram inserted from Balistier, 2000, 5.
