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

Convention

Hide-size convention to apply.

Custom acres/hide

Acres per hide when the custom convention is chosen.

Hides

Hides in the holding.

Virgates

Virgates (yardlands) in the holding.

Oxgangs

Oxgangs (bovates) in the holding.

Acres

Loose acres to add.

Sum Domesday-style land holdings into acres using the standard four-virgate 120-acre hide (1 hide = 4 virgates = 8 oxgangs) or a custom documented hide size, since hide sizes varied locally. 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]

Total acres

Total area in acres.

Virgates

Same area expressed in virgates.

Oxgangs

Same area expressed in oxgangs.

Hides

Same area expressed as a (possibly fractional) hide count.

• 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.

• Ell Yard Regional Converter

  Convert cloth lengths between ells and statute yards (36 in) using documented regional ell standards - English statutory 45 in, common Flemish 27 in, Scottish 37 in (approximate; local practice varied), or a custom length.

• Eschatocol Completeness Checker

  Score the closing protocol (eschatocol) of a charter against its four standard elements (dating clause, witness list, roboratio, sealing clause) under the stated heuristic: all four is complete, two or three is partial, fewer than two is fragmentary.

• 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.
