Winter Solstice Greetings
December 22nd 2008
The word “solstice” comes from the Latin sol, sun, and sistere, to stand. It is the time when the sun appears to stand still for a day or two in its relentless pacing from north to south and back again, the time when it pauses before turning to retrace the path it has been following as long as there has been an earth.
At the two equinoxes, the sun’s rising and setting place moves very fast across the horizon. But for a day or two on either side of June 21st and December 21st, it’s hard to tell that the spot has moved at all.
I sometimes speculate on how our ancestors must have felt as they watched their one source of warmth and light moving inexorably away, as the days grew shorter and colder. According to the elders, it had always come back before; but what if this time it just kept on going? Small wonder that December 25th, the first day the keenest-eyed member of the group could say for sure the sun had decided to return, has long been associated with joy, celebration, hope, and light.
The winter solstice, of course, marks the shortest day and the longest night of the year in the northern hemisphere. It is the official beginning of winter. For those of you who, like me, enjoy geometry, I offer my favorite definition: The winter solstice is the time at which the angle between the earth’s axis of rotation and the line connecting the South Pole to the center of the sun reaches its greatest value and begins decreasing again.
However you commemorate (or define) the season of the winter solstice, I wish you joy, celebration, and warmth.
