North Centred 360° Views from Ancient Sacred Places

Prehistoric Hor­izon Calendars used the shape of the horizon to measure luni-solar patterns in the sky all the way around. You too can learn to see it. These surveyed sites are mostly megalithic and mostly Irish. Some Rock Art, Barrows and British megalithic sites show that along the Atlantic seaboard of Europe (at least) ancient sacred monuments were all astronomically sited.

See the shape of the horizon and how it dances with patterns in the sky. Under­stand the significance of place. Try it Yourself! Go Out­side and look. Do the slow earthly dance that puts you in place and time with heaven. See approximate symmetries. See specific accuracies. Communicate with moon and sun. Know where you are. Know when you are. Take the time. Find a magic place ☺

These 360° thumbs give an overview of the physical relationship between heaven and earth at surveyed ancient sacred places. Can you see what they were doing? Some are more obvious than others. All show the limitations imposed by practical reality and many of them are more subtly accurate than first appearances might suggest. Can you imagine trying to find such a place by yourself?

• Vertical scale is x4 to make it easier to see the patterns.
• 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 [More].
