The Introduction surveys the range and diversity of engagements with the sublime across different areas of enquiry, genres of cultural productivity, and national traditions in late eighteenth- and early nineteenth-century Europe. It explores the close links between ‘the sublime’ and ‘the Romantic’ in academic discourse before outlining the history of ‘the Romantic Sublime’ as a critical construct. It argues for a potential disconnect between what scholars have called ‘the Romantic Sublime’ and how the sublime might actually have been produced, encountered, experienced, and understood during the Romantic period. A selection of key Romantic-period engagements with the sublime are discussed, as are the major scholarly histories of the topic, from the early twentieth century to the present day.
