The Trinity Gower D Scribe (fl. 1390–1420), often referred to simply as Scribe D, was a professional scribe and copyist of literary manuscripts active during the late fourteenth and early fifteenth century in London, England. Despite the fact that his real name long remained unknown, Scribe D has been described as "so well known to students of late Middle English manuscripts that he hardly needs any introduction". Identification and conjectured biography Scribe D was first identified in the 1970s by Ian Doyle and Malcolm Parkes, who noticed that the same scribal hand occurred in a range of prestige manuscripts of late fourteenth and early fifteenth century date. The hand has been characterised as "Anglicana formata at its best"; restrained, traditional and rather austere, with a slight influence of secretary hand. The manuscripts in which this hand appears show that Scribe D was active between the 1390s and 1420s. The spellings used by Scribe D have suggested to some critics that his original dialect was that of the south-west Midlands of England, particularly north Worcestershire; Kerby-Fulton has suggested that Scribe D can be regarded as one of a class of "'reasonably educated men' who came up from the provinces seeking their fortunes, Dick Whittington style". More recent scholarship has proposed he was in fact a Londoner influenced by his extensive work with manuscripts from the south-west Midlands, such as those of Langland. His particular specialisation in the works of John Gower seems to have resulted in him picking up several unusual word forms used by Gower, who had a London ("East Midlands") dialect with idiosyncratic Suffolk and Kent influences, and subsequently using them when copying the works of Geoffrey Chaucer. One of Scribe D's earliest identified works, based on the style of the illumination used in the manuscript, is the important "C text" of William Langland's Piers Plowman, contained in University of London MS. v.88. This contains scribal editing of "real skill" in addition to unique material written either by a "Langland enthusiast" or Langland himself. It may be significant that Scribe D's first surviving commission was for Piers Plowman, a work written in the same south-west Midland dialect that he could have spoken himself. Once established in London, Scribe D may have worked with other professional scribes. He is known to have worked on the same manuscript, the "Trinity Gower" manuscript, as the scribe of the Ellesmere and Hengwrt manuscripts
