In The Omega Stretch a limestone rock carries a fossil of sorts: The Greek letter Omega can be seen at one end, but it seems extruded, lengthened, like a large worm. The omega is set in the stone like one of those unfinished, non finito sculptures, where half or three-quarters of a carved human body seems to be imprisoned in the block from which it is trying to escape. But the sign also resembles a fossil—which it is, in a sense: stone as a material is fossil sediment that is millions of years old. Galileo thought that nature was written in mathematical language. Geologists read the superimposed layers of rock like palimpsests. If this sculpture was not a sculpture, it might prove that language and writing preceded us and, in this instance, that they might outlive us, fossilized, in the future.
