Among glass craftsman active in the 1st century A.D., the most famous and gifted was Ennion, who hailed from the coastal city of Sidon in modern Lebanon. Ennion’s glass stood out for its quality and popularity. His products are distinguished by the fine detail and precision of their relief decoration, which imitates designs found on contemporaneous silverware. This compact, but thorough volume examines the most innovative and elegant known examples of Roman mold-blown glass, providing a uniquely comprehensive, up-to-date study of these exceptional works. Included are some twenty-six remarkably preserved examples of drinking cups, bowls, and jugs signed by Ennion himself, as well as fifteen additional vessels that were clearly influenced by him. The informative texts and illustrations effectively convey the lasting aesthetic appeal of Ennion’s vessels, and offer an accessible introduction to an ancient art form that reached its apogee in the early decades of the Roman Empire.
