The long-awaited third book in this series showcases discoveries recorded by the Portable Antiquities Scheme, illustrating how objects evolved over 500,000 years. With its unique perspective, the PAS narrates the compelling story of human innovation, from early flint tools to artefacts from the end of the Roman period. The book explores how introducing new materials, particularly metals, spurred advances, presented challenges, and inspired new designs and methods. Richly illustrated, it places these finds within their cultural contexts, offering a fresh perspective that deepens our appreciation for these remarkable artefacts.
