Dr. Séumas Robinson is an Irish historian and independent scholar whose work spans the intersecting fields of ancient history, medieval Christianity, world archaeology, and the long global reach of religious traditions across the pre-modern world. Born and formed in the Irish scholarly tradition, he brings to his writing the particular gift of the outsider's clear eye - an ability to see the familiar frameworks of received history afresh and to recover the voices and communities that those frameworks have systematically marginalised. He lives and works in Westport, County Mayo, on the west coast of Ireland, where the Atlantic horizon serves as a fitting reminder that the most important stories are often the ones that lie beyond the edge of the known map. Dr. Robinson is the author of a wide-ranging body of narrative nonfiction works spanning subjects from the ancient civilisations of the Fertile Crescent and the Silk Road trading world to the criminal justice histories of the modern era. In all of his writing, he is animated by a consistent set of concerns: the recovery of institutional failure and its human costs, the dignity of marginalised communities whose histories have been written by those who defeated them, and the conviction that the deepest obligation of the historian is not to confirm what the reader already believes but to complicate it honestly and generously. The Nestorian Heresy is among the most personal and most ambitious of his works to date.
