  • Alignments - A name special to Carnac’s three successive groups of parallel rows of stones, starting above Carnac called Le Menec, Kermario, and Kerlescan and another found near Erdevan.
  • AMY - A megalithic yard which, in inches, expresses the true astronomical ratio of mean solar months to lunar months.
  • azimuth - the standard angular measurement of angles on the horizon, measured clockwise from zero degrees true North.
  • canevas - A technique of geometrical knowledge expressed within multiple square grids, noted and named by Schwaller de Lubicz in Pharaonic art and temple building.
  • Carnac - An extensive megalithic complex in southern Brittany, western France, predating the British megalithic.
  • chronon - The average excess of the day over the sidereal day, of 4 minutes, 1/365th of the Earth’s rotation, to catch up the sun.
  • circumpolar observatory - A geometrical arrangement suited to the tracking the motion of circumpolar stars, around the north pole, during the night.
  • Clava - A type of circular Bronze Age cairn, with a circular chamber, named after the group of three at Balnuaran of Clava, east of Inverness in Scotland. 
  • CMY - Crucuno megalithic yard of 2.7 feet, crucial to the factorization of time where 10 CMY become a lunar month of 945/32 days of 32/25 feet per day, the Iberian foot.
  • cromlech - Breton word for a rounded kerb monument or stone circle.
  • cubit - 3/2 feet of any sort, such as 12/7 Royal feet of 8/7 feet, and sometimes, a double foot.
  • Day-inch counting - The practice of counting the days, using inches or other small units, between synodic phenomena such as years or planetary loops.
  • dolmen - A chamber made of vertical megaliths upon which a roof or ceiling slab was balanced.
  • eclipse year - the time taken (346.62 days) for the sun to again sit on the same lunar node, which is when an eclipse can happen.
  • Ecliptic - The path of the Sun through the sky along which eclipses of sun and moon can occur, traditionally divided into the 365¼ parts of the solar year, each part then a DAY in angle rather than time.
  • English foot - The standard prehistoric foot (of 12 inches) representing a unity from which all other foot measures came to be formed, as rational fractions of the foot, a fact hidden within our historical metrology [Neal, 2000].
  • geodetic - Units of measures and monumental measurements relating to the numerical definition of the shape of the Earth by the late megalithic.
  • gnomon - ancient Greek: gnomon means “indicator,” “one who discerns,” or “that which reveals.”
  • Just intonation - A musical tuning system improving the Pythagorean system of tuning by fifths (3/2), by introducing thirds (5/4 and 6/5) to obtain multiple scales.
  • Landform - Those geometrically connected buildings, natural features or horizon events, necessary for quantifying astronomy, measuring the landscape or, in later times, connecting communities.
  • Lunation Triangle - The right-angled triangle within which the lengths of the two longer sides are the relative proportions of the solar and lunar years.
  • megalithic yard - Any 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.
  • megaliths - Structures 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.
  • Metonic - Greek: The continuous 19 year recurrence of the moon’s phase and location amongst the stars.
  • Metrology - The application of units of length to problems of measurement, design, comparison or calculation.
  • Nodal period - Usually referring to the backwards motion of the lunar orbit’s nodes over 6800 days (18.618 years), leading to eclipse cycles like the Saros.
  • PMY - proto-megalithic yard of 32.625 (261/8) day-inches, generated at Le Manio Quadrilateral as the difference between three solar and three lunar year counts.
  • Saros - The dominant eclipse period of 223 lunar months after which a near identical lunar or solar eclipse will occur.
  • Saturn synod - The 378 days between two retrograde loops of Saturn, equal to 54 seven-day weeks
  • superparticular - a ratio in which the numerator is one greater than the denominator.
  • Synodic - The recurring time cycle of a given celestial phenomenon seen from the Earth.
  • Trigon - The conjunction of Jupiter and Saturn every 19.8 years. Three trigons span the entire Zodiac in 60 years resembling the three steps the Indian god Vishnu took to span the whole universe.
  • 176/175 - Ratio crucial to maintaining integers (see geometry lesson 2) between radii and circumference of a circle, and crucial to the micro-variation of foot modules in ancient metrology.
  • 22/7 - The best accurate approximation to the π ratio, between a diameter and circumference of a circle, as used in the ancient and prehistoric periods.
  • 3-4-5 - The side lengths of the “first” Pythagorean triangle, special because the side lengths are successive small primes and, at Carnac, defined the solsticial extremes of the sun.
