October has brought a changed air, crisping and cooling in a gentle precursor to the onslaught of winter wind that comes from the north. Sunset has crept further into the day, and now, with the changing of the clocks, the balance of our days is shifting earlier into evening.
Less light however rarely means total darkness. The northern lights called us out just before the new moon, a faint green wash that could almost be imagined flickering above the hills. We switched off the house lights in an attempt to see them better, blending the garden and ourselves back into the night.
The departing light also takes with it the stream of noise emitted by our human world: voices, phones, TV, music, all fading from the air. From the glen over the water, we can hear the belligerent bellows of rutting stags. A pair of oyster catchers peep up from the nearby shore, while a female tawny owl haunts the trees behind us. Her solitary keewik remains unanswered, one half of twit as yet missing a male’s twoo refrain.
Writing in The Living Mountain on her one night sleeping outside under an October sky, Nan Shepherd told of ‘a night of the purest witchery, to make one credit all the tales of glamourie that Scotland tries so hard to refute and cannot.’ On a practical level, I know that we’re watching sun particles collide with the planet’s atmosphere. The shadowed flittering hints of Na Fir-Chlis, the nimble men, feel like a glamourie all the same: wisping movement and colour just beyond the realm of vision, just out of sight of my too-slow eyes.
Our eyes have evolved to function best in daylight, and it takes around ten to thirty minutes for sight to adapt enough to see those particles of light that filter through the dark. In the first few seconds, our pupils expand to let in as much available light as possible. Then, over the next ten minutes, the colour-gathering cones in our retinas reactivate the light sensitive chemicals left dormant during the day. If we stayed out for longer to watch that faint aurora, the rods in our eyes responsible for black and white vision would increase their sensitivity over several hours, opening further to the hidden magic of the night.
A quick snap with my phone camera would confirm the sight of those skybound dancers straight away, but just one glance at the phone screen would reset my eyes back to their default daylight settings. So instead we wait for the shifting green light to brighten, and for the stars that were there all along to emerge.
