Ronde-bosse et bas-relief is a practical guide to sculpture modeling that explores the techniques of creating both high relief (ronde bosse) and low relief (bas-relief) works. Written by Philippe Chazot and published by Ulisse in November 2001, the book offers step‑by‑step instruction for artists interested in mastering the form and texture of three‑dimensional art. Presented in a paperback format of 79 pages, it includes illustrations and explanations that help readers understand the material properties, tools, and methods needed to produce convincing relief sculptures. The guide is suitable for both beginners looking to acquire foundational skills and experienced sculptors seeking to refine their approach to relief work. With its clear focus on hands‑on practice, the volume serves as a useful reference for anyone engaged in the study or creation of sculptural art.
