Definition
A rotulus (plural: rotuli) is a formal record written on one or more skins of parchment sewn or rolled together. In old English and medieval Latin legal usage, the term refers both to the physical object — the parchment roll — and to the legal record contained on it. The great administrative and judicial records of medieval England were organized and preserved as rotuli: tax assessments, court proceedings, chancery filings, and royal correspondence each generated their own named rolls maintained by the relevant Crown office.
The term appears in the names of specific historical records. ROTULUS WINTONIÆ (the Roll of Winchester, or Roll of Winton) was a name applied in some sources to Domesday Book, though Burrill notes — following Spelman — that this designation more properly belongs to a similar survey compiled under King Alfred. The conflation of the two records in historical sources is a persistent research trap.
Common Language
Modern common usage (Wiktionary): A roll of parchment or papyrus written on to make a permanent record.
Historical common usage: The term has no independent entry in Webster's 1913, reflecting its status as a Latin term absorbed directly into legal and antiquarian usage rather than into general English vocabulary.
The common and legal meanings here are not in conflict, but the legal usage is substantially narrower and more specific: where ordinary usage treats rotulus as a generic description of any written roll, legal and administrative usage attaches the term to formal records of identified Crown offices and courts, each with its own custodian, preservation rules, and evidentiary standing. A researcher encountering rotulus in a legal source is dealing with a record of institutional authority, not merely a physical format.
Why It Matters in Research
The primary research challenge with rotulus is disambiguation. The same physical format — the parchment roll — underlies dozens of distinct named record series in medieval English administration. Encountering rotulus in a source tells you the form of the record but not its subject matter, origin, or evidentiary weight. Researchers must identify which roll is meant: the Rotuli Parliamentorum (parliamentary rolls), Rotuli Chartarum (charter rolls), Rotuli Litterarum Patentium (patent rolls), Rotuli Curiæ Regis (plea rolls), and so on. Each series was maintained by a different office, enrolled different categories of transaction, and has its own survival history and modern edition.
The Rotulus Wintoniæ problem is a specific trap. Burrill preserves Spelman's correction, but many earlier antiquarian and legal sources use the name interchangeably with Domesday Book. If you are working in sources predating Spelman's clarification — or in sources that ignored it — the reference may point to Domesday, to the Alfredian survey, or ambiguously to both. Verify which record the author actually had in mind before treating any claimed content as authoritative.
More broadly, the roll format itself affects how records were searched, cited, and copied. Entries on a roll are located by membrane number and sometimes by side (face or dorse). Later printed editions and calendars reorganize this material, sometimes silently. A citation to a rotulus in a seventeenth- or eighteenth-century legal argument may reflect the original roll, a contemporary copy, or a printed abstract — each with different reliability.
For corpus researchers, rotulus as a term signals that you are working in material that treats medieval administrative records as live legal authority, which is characteristic of certain periods of common law argumentation. Its frequency and context in a source can help date the source's frame of reference.
Historical Dictionary Support
Burrill's entry is brief but careful. It correctly identifies the physical composition of the roll (one or more parchment membranes), situates the term in old English law, and cites Bracton for contemporary usage. The Rotulus Wintoniæ sub-entry is notable for reproducing Spelman's distinction rather than simply equating the Roll of Winchester with Domesday Book — a clarification that many contemporaries and later compilers overlooked. No additional historical law dictionary on the current shelf provides a competing entry, so Burrill stands alone here. Researchers needing deeper treatment of specific roll series should consult Spelman's Glossarium Archaeologicum directly, as well as the introductory volumes to the Rolls Series and the various Record Commission editions, which remain the standard scholarly apparatus for these records.
Jurisdictional Note
Rotuli as a class of legal record are specific to the English Crown administration and its courts. The concept does not translate directly to Scottish, Irish, or continental practice, each of which developed distinct record-keeping traditions. Researchers working in Anglo-Norman or early Irish administrative history will encounter cognate roll-based records but under different institutional names and with different evidentiary treatment.
