Abstract Semiotics constitutes an untapped and interdisciplinary source of enrichment for the discipline of International Relations (IR) theory. We propose two visual metaphors to that effect to interpret the figure depicting the central claim of structural realism (SR) offered by late Kenneth Waltz who is one of the most disputed, read, and inspiring IR theorists. The figure is the tenor of both metaphors. The vehicles are two paintings by Mark Rothko, namely, “Green and Tangerine on Red” and the “Number 14.” The metaphors generate innumerable meanings for the tenor and eliminate the criticism that SR is a static and an ahistorical theory. Thus, they benefit the Discipline characterised by academic cleavages on the meaning of theory, science, and production of knowledge.
