The Idea of Iambos is a long overdue study of the genre of Greek iambic poetry from the perspective provided by ancient testimonies. Andrea Rotstein places research on iambos in the framework of a new methodological approach to ancient genres based on the cognitive sciences, offering an unprecedented study of ancient theories of genres and the way they affected ancient scholarship. Rotstein also examines the possibility of musical performance of iambic poetry as well as the various occasions of public performance, particularly at musical contests and rhapsodic recitals. Finally, she argues that, from the Archaic to the Classical period, there was a shift from the notion of literary class depending primarily on rhythm and on its archetypical representative, Archilochus, towards iambos as a genre defined mainly by invective as its dominant feature.
