This volume addresses the presentation of artistic processes and their materials in the 'Natural History' and focuses on the issues that lie at the root of Pliny's work: his account of the technological, economical, ideological, and aesthetic aspects of materials.0In his 'Natural History', Pliny the Elder organises his discussion of crafts according to the raw materials they utilize. However, scholarly literature has paid little attention to the aspect of materiality, preferring to focus on the biographies and achievements of ancient Greek artists. This collection instead addresses the presentation of artistic processes and their materials in the 'Natural History'. This approach corresponds with current developments in the study of Greco-Roman art, wherein scientific analysis of artistic materials including stones, pigments, and metal alloys, as well as a deeper understanding of workshop practices, has imposed profound changes on the methods used in the study of ancient artefacts.
