Archer and arched bleed alike
Insurrection, which does not exist, that's the point, is a diagonal cut away. A double-headed arrow, which wounds both the archer in the act of drawing back and the target when it falls. There's correspondence, but its other term, what it was the pejorative bastard cousin of - what we used to call revolution - isn't there, and definitely not as some haunted absence or trace. It's relation without a relative, adrift in the black, but stepping down and out. Hypotenuse of the knight's move.
That or the tired, somewhat strategic erasing of other words left on the board after an early morning section, with the end result of a two-bit Richter painting.
