How many turns in place on the school playground—your head flung upward, your eyes looking straight at the steeple of the church next to the gym— before you're gripped with vertigo or tip ground- ward? Once, on TV, a seismologist offered: what if, between the big magnitude quakes that flatten cities, disrupt our lives and push lava out of volcano cones, the tiny, daily tremors beneath the earth are too fast, too close together so they register on the needle as a line we think is flat? There are towns with roofs still sunk in hardened clay; buried belfries and plaster saints whose cloth robes have turned the color of dust, whose heads now resemble shredded dandelions. Stippled indentations on walls mark the places where birds careened out of the mouths of cliffs, colliding with their own displacement. I can't imagine how it is that a tortoise holds up the pillar of the world; how a legless snail holds tight to this surface of trembling filaments.
