Prehistoric Hor­izon Calendars are the views from Ancient Sacred Places. From those exact places, the shape of the horizon match­ed luni-solar patterns in the sky. All the way around, north-south axis of celestial rotation included. They were special places where heaven and earth could be seen to be in harmony, time could be measured and eclipses pre­dicted. Whole Horizon Analysis shows this clearly.

The pages listed here each contain thumb­nail pics for more than 180 surveyed sites, with links to bigger versions of the pics and to more information about each site. Low bandwidth users may use Site Lists to get named pages but won't get the global view.

Understanding of pre­historic tech­niques begins with visual comparison of different sites:

The 360° views have an exaggerated vertical scale which makes it easier to see the patterns; the others are all sectoral views at 1:1 scale ratio.

• The 360° views show how the overall shape of the horizon was matched to the overall luni-solar pattern.
• The sector views show local precision of fit in greater detail.
• See just how a match was achieved and which key points coincide.
• Every site is different but there are similarities, conventions even.

The Prehistoric Calendar pages explain solar and lunar notation used in the pictures and their underlying concepts in some detail. The Solar Calendar maps the annual round of the tropical year. The Lunar Calendar covers a longer period that maps cyclical changes in lunisticeLunistices are the most northerly and southerly moons of the month. The lunar equivalent of solstices - more. position that are indicative of the lunar orbit's 18.6 year rotation and thus of eclipse patterns.

These surveyed prehistoric monuments are mostly megalithic and mostly Irish. Some Rock Art sites, Barrows and British megalithic sites demonstrate that all stone & bronze age ritual monuments were astro­nomically sited (along the Atlantic seaboard of Europe at least). They all display a visible harmony between heaven and earth.

The key to finding such a place is movement within the landscape plus sky knowledge and it seems likely that each monument represents a node of special relationship within a wider sacred area.

To summarise:

• The pictures show views from monuments with the horizon accurately fitted to survey data.
• Luni-solar trajectories for the appropriate prehistoric period have been added.
• Orange Solar trajectories split the tropical year into 48 "Tweeks" (7.6 day mean) that are better regarded as quarter-months.
• Solid Blue Lunar lines split cyclical lunistice position variation into 16 periods of about 14 months each.
• Lunistices are the most northerly and southerly moons of the month.

See just how well the landscape has been fitted to the heavenly patterns at every site.
