This study examines the interface between some of the most authoritative Romantic writers and "Celticism", an emergent strand of cultural ethnicity during the eighteenth century. The collected essays examine engagement with Celtic culture by writers such as Blake, Wordsworth, Scott, Byron and Shelley, as well as engagement with the Romantic sensibility by those from "within" the Celtic nations of Britain. The collection, thus defines the differences between "Celtic" and "British" in the Romantic period.
