This essay marking the 250th anniversary of Walter Scott's birth reflects on the current state of Scott studies, the scholarly directions in which it might develop, and ways in which the relevance of Scott’s work may be re-discovered and re-invigorated for contemporary audiences. In particular, it examines scholarly and critical attitudes to Scott's work over the past 50 years through papers given at the triennial international Scott conferences initiated in Edinburgh in 1971, alongside developments in public engagement at Abbotsford House and elsewhere during the 250th anniversary year.

Scott's Last Words, Peter Garside

Studies in Scottish Literature

Walter Scott’s dying words as recounted by J. G. Lockhart, widely accepted by in the Victorian period, have since been seen as largely fabricated. In 1938, H. J. C. Grierson blamed Lockahart’s “pious myth” on a “lady relative” of Scott’s anxious to deflect future detractors who might vilify Scott as irreligious. The concerened lady, unnamed by Grierson, was Mrs Harriet Scott of Harden, one of Scott’s first confidants, early adviser on literary matters, and later nearby neighbour at Mertoun House. Her positive influence on Scott, still underestimated, is hardly that of the “evangelical lady” featured regularly in post-Grierson Scott biographies. …
