Irish megalithic sites linked to the Sun and the Moon
Tombs at the archaeological site of Loughcrew in County Meath align with the rising Sun at the spring and autumn equinoxes. The inside of the chambers are spectacularly illuminated by a shaft of sunlight at dawn on Spring equinox, said Frank Prendergast of the Dublin Institute of Technology. It suggests settlers in the area some 5 to 6,000 years ago knew the yearly cycle of the Sun and perhaps centred their lives around it.
Tombs found elsewhere in Ireland have been found to point towards the rising Sun at the summer and winter solstices. At these times, the Sun reaches its most northerly and southerly points in the sky, which can be easily observed from any place on Earth. The equinoxes - in late March and late September - are not so obvious and can only be pinpointed by tracking the passage of the Sun across the entire year. Why tomb builders wished to do this remains a mystery but it suggests the Sun was at the heart of ritual and ceremonial practices of ancient people. "They would have attached a sense of sacredness to their landscape and the sky and they would have done that by building the monuments the way they did; decorating them with a kind of rock art; and associating some of these monuments with key astronomical events such as a significant rising and setting points of the Moon and Sun." said Frank Prendergast.
Details have also be revealed of how Bronze Age stone circles in Ulster relate to both the Sun and the Moon. Archaeologists believe there could have been separate lunar and solar traditions, possibly at different times in history. But Professor Clive Ruggles, of the University of Leicester, said great care was needed in interpreting them. "Just because a monument is aligned in a direction that we would be tempted to interpret as astronomically significant, such as the direction of sunrise or sunset on one of the solstices, this might not have been intentional," he said. He believes the study of astronomical alignments gives an insight into how people comprehended the world in the past.
