This book explores the optically vibrant paintings executed by the Italian Divisionists during the late 19th century and, for the first time, examines their relationship to Neo-Impressionism. Artists from both these movements subscribed to a painting technique rooted in colour theories, held radical, left-wing political views and pursued similar subject matter, from idyllic landscapes to society's problems. Bursting with reproductions by the genre's leading proponents, this catalogue also includes essays by noted scholars that shed new light on this hitherto neglected area of European art history.
