This book addresses the complex question of the significance of regions in the creation of Romanesque, particularly in relation to transregional and pan-European artistic styles and approaches. Individual chapters explore the generation and reception of forms, the conditions that give rise to the development of transregional styles and the agencies that cut across territorial boundaries. There are studies of regional styles in Aquitaine, Castile, Sicily, Hungary and Scandinavia, workshops in Worms and the Welsh Marches, the transregional nature of liturgical furnishings, the cultural geography of the new monastic orders, metalworking in Hildesheim and the valley of the Meuse, and the links which connect Piemonte with Conques.
