What is a line? A line, real or imaginary, signifies a path, a continuous point, a moving mark. This simple word not only organizes our perception, but determines our basic rapports between front and back, deep and shallow, in and out, near and far, up and down, past and present, today and tomorrow. Our physical geography, our relations to nature, and even the whole domain of our culture, are topographies structured by lines. Kal Mansur's work figures an artist's apprehension. —V.Y. Mudimbe, On African Fault Lines (2013)
