Carved in Portuguese limestone from a quarry under UNESCO protection, Not I frames a serifed I-shaped void in a stone tablet. Like a spirit figure, the sculpture describes an absent presence, simultaneously and equally not: I/One/First. A usually crisp aye/ai/I-sound softens to a barely audible whisper. This voice is held in the void, where internal curves suggest a primitive bust or torso, a body held in suspension between head and shoulders or chest and hips, and a slippage between subject and object. With the addition of a light source, the void casts a shadow, strikingly present like an ephemeral being; shedding light on a transient existence. The simple beauty of this hesitant assertion is found also in close view. The ancient stone outline holds traces of tiny fossils, and smooth internal curves, a cave-like space reconnecting ‘I/One’ to its primordial roots.
