Ancient coastal tales reveal deep memories of land, sea, and survival. What if the legends of submerged cities, land-making witches, and sea-crossing bishops are not mere inventions but echoes of real events? Whispers from Celtic Seas revisits coastal traditions from the Celtic fringes of northwest Europe, showing how they preserve memories of dramatic environmental change--floods, land loss, and shifting shorelines--carried forward through oral storytelling for generations. Drawing on cutting-edge geological and archaeological research, this book recasts these tales not as fantasy but as historical testimony grounded in lived experience. With clarity and insight, it also brings to life the tellers and collectors of these stories, tracing how oral knowledge endured even as literacy spread. It is a compelling invitation to listen again to old stories, and to hear what the land and sea remember.
