Emotions are everywhere in the ancient world: in everyday transactions, in interpersonal relationships, in religion and politics, in the objects that people use in their daily lives, and in the buildings and spaces they live in. Classical literature is rich in representations of emotion and the actions that emotions motivate, while Classical rhetoric and literary theory concentrate above all on the emotional effects that texts and performances have on readers and audiences. Greek and Roman historians weave complex narratives in which the emotions of author, narrator, historical characters, and audiences are intricately intertwined. The visual arts, music, and dance are theorized in terms of their emotional properties and effects. The West’s earliest philosophical and scientific approaches to emotion in ancient Greece and Rome engage what are still fundamental concerns. This volume surveys this vast field to demonstrate how emotion history is an indispensable aspect of the cultural history of the Greek and Roman worlds.
