Thought for the day, Wednesday 28th May

“In ancient times, knowledge of the tides and seasons was vital, sacred knowledge that kept the tribe in harmony with the laws of nature. The mysteries of sun, moon, and stars that collectively describe the intricate dance of the day, the month, and the year were so important that a whole new class of society sprang up: the sacred clan who, under a variety of names, maintained watchful vigil over these movements that governed the sowing and reaping of crops, the movement of animals, the run of fish. These people were those who had an aptitude for minute and careful observation. They also had an infinite patience that we now find hard to comprehend.

They would watch and record the patterns and cycles every day, every month, every year, over a whole lifetime. Their work was continued by their offspring into many generations, until eventually the vast workings of the cosmos formed meaningful shapes and patterns. Over the centuries, their observations would result in the erection of stone circles and megaliths, each stone sited according to their observations. It was said of St. Columba that he could understand the harmonious dance of the moon and sun, read the tides of the sea, and enumerate the stars of heaven. This alone is proof that as late as the sixth century, the foundation lore of the sacred clan was being passed down.

Today, though we possess tide tables, calendars, and ephemerides with which to track the seas, the days, and the movements of the heavens, the sacred knowledge of their mysteries is own own special heritage.”

Second place in the IAU OAE Astrophotography Contest, category Star trails: Stone Star Circles, Startrails above Stonehenge, by Till Credner, Germany. Astronomy is one of the oldest (if not the oldest) of the sciences, and as such has connection to various cultures over millennia. This image in a way conveys this relationship by being contextualised in Stonehenge. There is much research into what astronomers call archeoastronomy sites, and how they connect to the sky (for example, seasons, phases of the moon and much more). Civilizations across time and from all over the world have their own views and interpretations of what they see in the sky, and this has been tied not only to culture but also to the people’s day-to-day and seasonal activities. The “concentric circles” which are often referred to as “star trails”, are the result of the apparent motion of the sky, which is in reality due to the rotation of the Earth on its axis. The small dot appearing towards the top center of the image is Polaris – The North or Pole Star. Polaris is only visible to observers in the Northern latitudes. The height of the Pole Star can be used to infer the observer’s actual latitude. Stonehenge is located at around 51° North. This image is taken from one of the most notable ancient sites in the world, brings us back in time, and makes us wonder about the stories told by the people that lived in that place many millennia ago.
