The Celtic World

A History

John Waddell

“Echoes of the Celtic past continue to stir the modern imagination, inspiring artists, musicians, writers, poets. Filmmakers, philosophers, spiritualists, historians, linguists and archaeologists, among others. Where these concepts about the Celts originated from and how these ideas developed and changed over time depending on the social, cultural and political environment of the day is the subject of this gripping book by John Waddell … Waddell takes the reader on a survey through centuries of scholarship to determine how we came to know what we know about the Celts and concludes by looking to the future of Celtic Studies. It is a deeply personal tour and Waddell is the perfect guide. His prose is elegant, effortless and a pleasure to read. The inclusion of over a hundred select colour photographs with maps are a bonus … [this] book is an excellent companion for anyone interested in connecting with the Celts and their world.” Chris Doyle, the Irish Times [Saturday, 4th July, 2026]

“Waddell’s introduction is short and precise and a perfect lead-in to what is a dense but very accessibly written piece of scholarship: ‘… it will become clear, in this study, that a Celt was someone who first and foremost spoke a Celtic language.’ From that starting-point the reader can enter the Celtic world with an understanding of the thread that links the multidisciplinary world of Celtic scholarship over many countries. One of the most enjoyable aspects of reading this book was the continual discovery of why certain beliefs about the Celts became widespread. As is standard with Four Courts Press, the book is a beautiful production, filled with a wide variety of images.” Grace O’Keeffe, Archaeology Ireland [Vol. 40. No. 2. Summer 2026]

“[The Celtic World] has reignited and widened the debate on the origin of the Celtic-speaking peoples of Europe, including our ancestors on this island. This debate has raged for over a century and a half, if not longer, often with academic opinions entrenched and, at times, imbued with a political or racial bias that inevitably produced more heat than light. [...] This book is a historical exploration of how our understanding of the ancient Celts and the concept of a European-wide world inhabited by Celtic-speaking people developed over time. The debate continues…” Ireland’s Genealogical Gazette, Vol. 21 No. 3, March 2026

“After a necessary brief introduction to the ancient Celts and the sources that have taught us about them, Waddell sifts through the layers of Celtic scholarship undertaken since the Renaissance, detailing the projects of scholars in the various genres that led to the picture of the Celtic world that we have today. [...] Ireland is given considerable but not disproportionate attention. [...] The Celtic world presents a clear narrative overview of most of the major developments in the history of Celtic scholarship over the last few centuries [...] The Celtic world is a beautiful book. The 100 lavish illustrations do justice to the richness of the material under discussion, and Four Courts Press [...] is to be congratulated for making this book reasonably priced. Waddell has provided a clear survey of earlier periods of the history of Celtic scholarship and given historical form to more recent ideas and events within the field.” Ian Stewart, History Ireland, July/August 2026
