"...I saw a circular piece of that sky appear, suddenly detached, blackened, and backlighted; from nowhere it came and overlapped the sun. It did not look like the moon. It was enormous and black. ...It looked like a lens cover, or the lid of a pot. It materialized out of thin air - black, and flat, and sliding, outlined in flame." Author Annie Dillard describing a solar eclipse she observed in 1979.
