Brussels.- X and Y are the symbols of interchangeability: X can stand for anything, as Y can stand for anything except what X stands for. In the XY coordinate system, the point where the horizontal x-axis and the vertical y-axis intersect is the point zero, the origin and in essence the Void from which Everything arises. X and Y are also the sex chromosomes that form the basis of life. The coming together of sperm and egg cell creates the female XX or male XY cells. “X & Y” is the title of the exhibition which Thomas Lerooy created for Galerie Rodolphe Janssen, which consists of an ensemble of five new drawings and a bronze sculpture. The exhibition is on view until May 14th 2011.
