"Gaston de Blondville" was begun in 1802 and published posthumously in 1826, edited by Sergeant Talfourd. Its inspiring cause was a visit which the author made in the autumn of 1802 to Warwick Castle and the ruins of Kenilworth. The introduction has the usual fiction of an old manuscript found in an oaken chest dug up from the foundation of a chapel of Black Canons at Kenilworth: a manuscript richly illuminated with designs at the head of each chapter--which are all duly described--and containing a "trew chronique of what passed at Killingworth, in Ardenn, when our Soveren Lord the Kynge kept ther his Fest of Seynt Michel: with ye marveylous accident that there befell at the solempnissacion of the marriage of Gaston de Blondeville. With divers things curious to be known thereunto purtayning. With an account of the grete Turney there held in the year MCCLVI. Changed out of the Norman tongue by Grymbald, Monk of Senct Marie Priori in Killingworth." Chatterton's forgeries had by this time familiarized the public with imitations of early English. The finder of this manuscript pretends to publish a modernized version of it, while endeavoring "to preserve somewhat of the air of the old style." This he does by a poor reproduction, not of thirteenth-century, but of sixteenth-century English, consisting chiefly in inversions of phrase and the occasional use of a _certes_ or _naithless_. Two words in particular seem to have struck Mrs. Radcliffe as most excellent archaisms: _ychon_ and _his-self_, which she introduces at every turn.
