Today is the shortest day of the year. As I write this, it is just gone three in the afternoon and there is already a hint of dusk about the sky. Within an hour or so, night will have fallen, and the Christmas celebrations will soon be one day nearer. But today is a celebration too – an ancient midwinter festival that has been celebrated in Britain for millennia, long before Christianity (or even the Romans) arrived on these isles. Today is also the Winter Solstice.
The word ‘solstice’ comes from the Latin sol (sun) and sistere (to stand still), which expresses the idea perfectly as the sun appears not to move on the horizon. In astronomical terms, the Solstice marks the shortest day – that is, when the sun is at its lowest arc in the sky because the tilt of the earth has moved our hemisphere furthest away from the warmth and power of the sun. This is the last day before the winter nights begin to shorten and the hours of daylight start to increase again.
To us modern folk, the reversal of the shortest day means little more than mild relief that we won’t have to get up in the dark of the morning for very much longer, but to our ancient ancestors it was far, far more important than that. Prior to everyone owning diaries and calendars which neatly divide the months and seasons by date, astronomical events, such as the movement of the sun across the sky and the phases of the moon at different times of the year guided the existence of our ancestors, controlling when they sowed their seeds or took their animals to be mated, for example. The sun, in particular, was very important to this process, which (partially) explains why the Solstice has long been celebrated as its return and rebirth.
