Over the past few decades, metaphor has come to be seen as a trope that governs thought, not just language. A consequence of accepting this view is that its manifestations should be examined in other media than language alone. Together with metaphor’s role in gesturing, its function in visuals has hitherto been the richest area of non-verbal research. This chapter provides an overview of issues that deserve attention in the investigation of pictorial (or: visual) metaphor and multimodal metaphor involving visuals. These issues include: monomodal versus multimodal metaphor; identifying non-verbal metaphor; creative versus structural metaphor; diegetic versus extradiegetic source domains; metaphor in static versus dynamic discourses; metaphor and other tropes.
