the political landscape of what would become England. The opening of the book sets a tone of scholarly investigation as Kerslake begins by discussing the origins of the church of St. Werburgh in Bristol and its historical significance. He introduces the idea of using scant historical records and monumental evidence to infer the early foundations of local history. The text elaborates on the territorial boundaries and rivalries between Mercia and Wessex, particularly through figures like King Æthelbald, and traces remnants of Mercian influence in place names and church dedications across the region. Kerslake's analysis combines historical narrative with archaeological insights to uncover the residues of Mercian supremacy, initiating an exploration that intertwines local history with broader national narratives.
