Prehistoric (5000-2000 BC)
Quantifying astronomical time and geophysical space, using alignment, counting and geometry.

- Story of Three Similar Trianglesfirst 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 “Story of Three Similar Triangles”
- Working with Prime NumbersWikipedia 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 MonthsMegalithic 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 AstronomyThe ratios of ancient metrology 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 it out (say East-West), starting at the beginning of the shorter rope length, … Continue reading “Use of foot ratios in Megalithic Astronomy”
- Models of Time within Henges and Circlesimage: 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 Periodimage: Jupiter with now-shrunken red spot – Hubble Space Telescope Though megalithic astronomers could look at the sky, their measurement methods were only accurate using horizon events. Horizon observations of solstice sunrise/set each year, lunar extreme moonrises or settings (over 18.6 years) allowed them to establish the geometrical ratios between these and other time periods, … Continue reading “Megalithic Measurement of Jupiter’s Synodic Period”
- Erdeven Alignment’s counting of Metonic and Saros PeriodsThe 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 alignments to horizon events gives a partial but useful explanation, since menhirs (or … Continue reading “Erdeven Alignment’s counting of Metonic and Saros Periods”
- Counting lunar eclipses using the Phaistos DiskFigure 1. The location of Phaistos Palace atop a commanding hill in the middle of the fertile Massara valley in southern Crete. 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. This paper* concerns itself … Continue reading “Counting lunar eclipses using the Phaistos Disk”
