‘I have dreamed geometry / I have dreamed the point, the line, the plane, and the volume / I have dreamed yellow, blue and red.’ These lines from Jorge Luis Borges’s poem ‘Descartes’ (1981) are found on the opening page of the catalogue to ‘Géométries sud, du Mexique à la Terre de feu’ (Southern Geometries, from Mexico to the Tierra del Fuego). A fitting epigraph, they announce the vertiginous profusion of coloured shapes in the nearly 250 works by more than 70 artists and creators from the pre-Columbian period to the present.
