'Nile' reflects King's concern with the expressive possibilities of abstract forms, particularly in regular or rhythmic progressions. A sequence of rectangular planes traverses the spectator's field of vision. This evokes a sense of flow proceeding from warm, advancing red to cool, receding blue. The allusion to river-like movement (hence the title) is continued in the crossed diagonals on the ground. These set up a counter-rhythm, suggesting a river's undertow. Despite these associations, King's principal aim is one of confrontation rather than representation. Thus the work's imposing scale relates to human proportions so that the spectator senses its dynamic presence.
