2017 SOLAR ANALEMMA - CALLANISH STONES Taken by Giuseppe Petricca on January 1, 2017 @ Isle of Lewis, Eilean Siar, Scotland



Solar Analemma 2017 - Callanish Megalithic Stones

In the composition (a three shot vertorama for the background and 42 different solar pictures) we can clearly see the analemma over the magnific megalithic site of Callanish, almost 5000 years old! To walk amidst the monoliths placed on the ground according to a specific design, probably dedicated to the Moon and her phases almost manages to transport the traveler back in time, when the first civilizations colonized these islands on the edge of the Atlantic!

An experiment that I wanted to try again, after the successful experience of last year, always fighting with the ever fast chaning weather of these places. I managed, however, to photograph more images than I anticipated, creating a complete analemma, with the inferior (Winter) culmination of the Sun purposelly behind the highest stone of the site.

This strange figure, with a shape of an 8 or an infinite, the analemma, is caused by the axial tilt of our planet, and by the elliptical shape of our orbit around the Sun. If we take a picture day by day, always at the same hour, the Sun is not in a fixed position, but it slowly climbs up and then down the curve. All this, framed in a breathtaking ancient landscape, as old as the men and women which under the same Sun built this magnificent lunar observatory!
