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

Single-storey a

Count of single-storey (Caroline) a glyphs sampled.

Double-storey a

Count of double-storey a glyphs sampled.

Threshold %

Minimum single-storey share in percent to raise the 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). 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]

Share %

Single-storey a as a percentage of all sampled a glyphs.

Carolingian profile

True when the single-storey share meets the 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.

• Batarde Mix Proportion Calculator

  Compute the textualis-versus-cursiva proportions of a batardesque hand and classify the mix under the stated heuristic: shares within 20 percentage points of each other are balanced, otherwise the larger share dominates.

• 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%).

• Chirograph Wavy-Cut Checker

  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.
