Aldo Scaglione has published extensively in literary history and literary criticism in the areas of Romance literatures, the Renaissance, Humanism, and theory of language and rhetoric. This collection of previously published essays assembles the most relevant studies on theory of language development and theory of style in specific geographic areas and in general terms. The essays find a common thread and matrix in their reference to the traditional theory of the Arts of Discourse, or Trivium Arts, the core of the Liberal Arts system. The languages most directly involved range from Latin and Greek to Italian, French, and German. The connecting link is the perception that literature grows in a symbiosis of convergent disciplines that affects authors and readers alike.
