The Hidden Portrait Gallery: Sitter-Overlay Facsimile of the Bedford Psalter-Hours
An interactive digital book where users can tap on art to see the real medieval people hidden inside the drawings.
An interactive online facsimile of the Bedford Psalter-Hours in which each painted initial can be tapped to reveal the real medieval person concealed inside it — the poets and courtiers of the Lancastrian court — turning a 600-year-old prayer book into a navigable portrait gallery for literature courses.
Concept
A licensed interactive facsimile of the Bedford Psalter-Hours (British Library Add. MS 42131) built around one toggle: 'show the hidden faces.' Every one of the 290 portrait-bearing initials is outlined and numbered; tapping a head enlarges it and shows the proposed sitter, their role (prophet, preacher, penitent), and the subtext created by their repeated appearances. A 'gallery mode' walks a class through the book initial by initial, letting students watch Gower recur ten times and trace the Lancastrian friends and foes encoded at the Psalter's text divisions. Crucially, the overlay works by marking the image itself — outlines, highlights, numbered heads — rather than relying on prose captions, because eye-tracking evidence shows that textual descriptions of artworks do not, in most cases, change how viewers actually look at them; direct visual cues do the work captions cannot.
Why now
The paper supplies the complete, citable annotation layer: 290 of 300 minor text divisions illustrated with portrait heads; a concealed portrait gallery of Lancastrian contemporaries that is 'almost without precedent' in the Middle Ages; Gower appearing ten times to lend his moral authority to the imagery; and the book identified as the only manuscript the Duke of Bedford is known to have commissioned in England. For courses on Chaucer, Gower, and Hoccleve — the canonical late-medieval English poets whose portraits sit in these initials — this is ready-made teaching content. The older eye-tracking study sharpens the design: participants believed descriptions changed their viewing, but their eye movements showed they did not, so the product's value must come from visually marking the initials rather than text alone.

AI assessment
A highly focused educational tool that transforms a specific academic discovery into a tangible classroom asset, though its market is limited to a niche academic subset.
- Evidence strength 5/5
- The idea directly implements the specific findings of the first paper (the 290 portraits and Gower's repetitions) and applies the behavioral insight from the second paper regarding visual cues over text.
- Market pull 2/5
- The target audience is restricted to a very small number of university courses specializing in late-medieval English poets, limiting the total addressable market.
- Novelty & moat 2/5
- It is a direct application of the 'Recurring-Sitter Finder' concept applied to a specific manuscript, moving from a general tool to a specific curated instance.
- Feasibility 5/5
- The annotation layer is already provided by the research; building a web-based image overlay with toggle states is a straightforward development task.
- Wedge clarity 5/5
- The wedge is exceptionally sharp: a single, specific manuscript used for a specific set of literature courses.
- Simplicity / focus 5/5
- The product is a single-purpose interactive facsimile with one primary feature (the toggle), avoiding any platform bloat.
