Abstract
As a contextual phenomenon, metaphor operates in fundamentally different ways in divergent universes of discourse. In historiography, Maurice Mandelbaum's incisive typology of forms of historical discourse affords a comprehensive conceptual basis for foregrounding the three fundamental ways that metaphor functions. Each of the three functions of metaphor facilitates historical understanding on a different epistemological level. Heuristic imagery advances deliberative, analytic understanding and falls within the domain of explanatory discourse. Depictive imagery presentationally facilitates the apprehension of meanings and occurrences; it is a component of narrative, which includes sequential, discourse. Finally, cognitive imagery, operative on the metahistorical plane, orchestrates interpretive discourse and thereby governs the way that events may be known in and of themselves
