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

Upper letters

Letters of the chirograph word surviving above the cut.

Lower letters

Letters of the chirograph word surviving below the cut.

Letter tolerance

Maximum allowed difference between the two letter counts for a match.

Wavy cut visible

Whether the indented wavy cut line is actually visible.

Assess a cut-apart chirograph under the stated heuristic: halves whose surviving letter counts differ by no more than the tolerance count as matching when a wavy cut is visible, mismatched otherwise, and indeterminate whenever no wavy cut is visible. 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]

Letter difference

Absolute difference between the two letter counts.

Balance ratio

Smaller letter count divided by the larger (1 when perfectly balanced).

Verdict

Stated-heuristic verdict for the two joining halves.

• 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.

• Insular Family Flag Checker

  Tally four documented Insular script features (insular g, insular delta-shaped d, long-descender insular s and the Tironian et) under the stated heuristic: no features means unlikely, exactly one is possible, two or more is probable Insular.

• 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%).

• Schwabacher Fraktur Note Generator

  Generate a dated-note-style verdict for late Gothic textura under the stated heuristic on sampled ascender forms: more than 60 percent looped ascenders leans Fraktur, under 40 percent leans Schwabacher, and anything between is mixed.
