In what is presented to me as space of light, that which is gaze is always a play of light and opacity. It is always that gleam of light – it lay at the heart of my little story – it is always this which prevents me, at each point, from being a screen, from making the light appear as an iridescence that overflows it. In short, the point of gaze always participates in the ambiguity of the jewel.
