Welcome back, Grian!
It’s nothing new, marking the turning of seasons by the waxing and waning appearance of the sun. Certainly the most striking is during the morning of the winter solstice, when once-lengthening nights roll over into ever-lengthening days and the promise of warmth, new crops, and renewed life. So of course ancient people celebrated the midwinter return of the sun.
And where better to experience it than through the carefully-aligned great trilithon, the largest of the standing stones of Stonehenge? It and the others were lined up thousands of years ago to pinpoint the specific morning that for eons has heralded the return of Grian – which Celtic people called the sun.
