Stone Age ‘telescopes’

horizon astronomyWere some stone age monuments used to enhance the viewing of a particular section of the night sky?

Were some megalithic sites built to help isolate star constellations at certain times of the year?

For example the first rising above the horizon of an important seasonal or festive marker star?

If plasma phenomena were witnessed in the ancient skies, as seems to be confirmed by the sudden change to stark white petroglyph figures chipped into rock around the world, could some of these stone structures (passage tombs, passage graves, circular earth mounds) have been orientated towards a Squatter Man or Axis Mundi near the poles?

Astronomers are exploring what might be described as the first astronomical observing tool, potentially used by prehistoric humans 6,000 years ago. They suggest that the long, narrow entrance passages to ancient stone, or 'megalithic', tombs may have enhanced what early human cultures could see in the night sky, an effect that could have been interpreted as the ancestors granting special power to the initiated.

Could Malta's megalithic buildings, so called Temples, have been constructed to also help with the observation of Peratt Instabilities in the ancient skies?

Horizon Astronomy

Something that was designed for the summer solstice or other solar positions in the sky could also be utilised for the night sky and the stars or other visible objects.

Newgrange is best known for the illumination of its passage and chamber by the Winter Solstice sun. Above the entrance to the passage of the mound there is a opening called a roof-box. On mornings around the winter solstice a beam of light penetrates the roof-box and travels up the 19 metre passage and into the chamber. As the sun rises higher, the beam widens so that the whole chamber is dramatically illuminated.
