Rebecca Solnit has an article in Orion magazine this month called, "The Limits of Landscape - Going beyond traditional ways of seeing."
Here is part of one paragraph to contemplate. She is discussing "the stone circles that the prehistoric Irish erected for ceremonial and celestial-observation purposes."
"A picture may capture a moment of time - late afternoon light raking over, say, the golden rocks of the deep desert - but a stone circle calls attention to time in a deeper sense, to the swing of stars from north to south across the sky over the course of a year, and to calendrical time. It is not just something to behold, but an invitation to observe and connect. It doesn't represent the landscape, but helps make the most invisible forces - time itself, and the rotation of the Earth - present, and brings you into alignment with these forces."
-- Rebecca Solnit
This winter light brings awareness of stones. Perhaps, make a circle of your own, and watch time and the rotation of the earth, and align, both, within, and without.
