Use this palaeographic utility to apply a stated dating, script, abbreviation, codicological, metrological, layout, or condition rule consistently while preparing manuscripts for scholarly review.

Gilded sides

Sides of the miniature enclosed by gold (0-4).

Border width (mm)

Mean width of the gold border in millimetres.

Width threshold (mm)

Minimum border width for a confirmed frame.

Detect a gold frame around a miniature under the stated rule: class from the count of gilded sides (0 none, 1-3 partial border, 4 full frame), with the frame only 'confirmed' when the mean gold border width also meets a threshold (default 2 mm). The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Frame class

Frame class from the gilded side count.

Above threshold

True when the mean border width meets the threshold.

Confirmed full frame

True for four gilded sides that also meet the width threshold.

• Script and manuscript evidence varies by language, region, institution, period, scribe, material, restoration, and cataloguing convention. A heuristic flag or score is not an authoritative date, hand attribution, reading, provenance, or conservation diagnosis.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Retain page images, scale, foliation, material, provenance, diplomatic transcription, uncertainty, and comparison exemplars; confirm conclusions with codicological context and specialist judgment.

• Nib / X-height Consistency Checker

  Check that repeated x-height measurements agree within tolerance under the stated rule: spread is (max-min)/mean in percent and the hand counts as consistent when spread does not exceed the tolerance (default 10%).

• Scribe Change Detector

  Flag a possible change of scribe under the stated rule: each metric (line spacing, letters per line) is compared by the symmetric percent deviation |a-b|/mean(a,b)*100, and a deviation above tolerance (default 5%) on either metric flags a change.

• Carolingian Single-storey Flag

  Flag a Caroline-minuscule-like script profile under the stated heuristic: a hand counts as showing the single-storey Caroline a profile when its single-storey a share reaches the threshold percentage (default 80).
