Definition
A written summary or schedule of matters to be inquired into, or presented before, justices in eyre, justices of assize, or justices of the peace during their sessions. Chapiters were formal documents delivered by the king to itinerant justices as direction for their proceedings, setting out the particular subjects — crimes, abuses, administrative matters — upon which presentments and inquiries were to be made during a circuit or session. Also called capitula itineris (chapters of the eyre) or articles.
The term belongs entirely to the procedural apparatus of medieval and early modern English royal justice and has no living legal application.
Common Language
Modern common usage (Wiktionary): An obsolete form of "chapter," or the capital (uppermost decorative part) of a column in architecture.
Historical common usage (Webster's 1913): "A capital. [Obs.]" Webster's cross-references the architectural sense and notes the legal sense secondarily, defining it as a written summary of matters before justices in eyre — essentially mirroring Jacob's law dictionary.
The gap is worth noting: a modern researcher encountering "chapiter" in an architectural or biblical text (the word appears in Exodus in the King James Bible referring to column capitals) and one encountering it in a legal record are reading an entirely different word that happens to share a spelling. The legal chapiter is a procedural instrument of royal justice; the architectural chapiter is a structural element. Neither meaning survives in active use, but conflating the two when reading old records would produce confusion about context.
Common Confusion
Chapiter is sometimes loosely equated with "articles" in secondary sources, and the terms functionally overlap — both refer to written schedules of inquiry. However, "articles" is the broader term used across many procedural contexts (articles of impeachment, articles of the clergy), while chapiter refers specifically to the schedule of heads of inquiry delivered to itinerant justices. Researchers should also avoid conflating chapiter with "chapter" in the sense of a legislative division or chapter of a religious house, even though the Latin root (capitulum) underlies all three uses.
Why It Matters in Research
Chapiter is an extinct procedural term that appears almost exclusively in sources dealing with the eyre system and early English common law administration — roughly the late thirteenth through fifteenth centuries. Researchers working with records from justices in eyre, assize records, or treatises such as Britton or Fleta will encounter the term and need to understand it as a formal instrument, not mere shorthand for "topic" or "chapter."
Key navigational points:
First, the Statute of Westminster I (1275), c. 27 — cited by Burrill — is the anchoring statutory reference. Researchers tracing the formal role of chapiters in the eyre should begin there and work outward through the treatise literature.
Second, Britton (c. 3) and the Termes de la Ley are the primary explanatory sources in the historical corpus. Britton's treatment is particularly useful because it situates the chapiter within the broader machinery of the eyre's opening proceedings.
Third, the Latin equivalent capitula itineris will appear in Latin-language records and Year Book annotations where the French or English form does not. Researchers using Law Mind's medieval records must track both forms.
Fourth, the eyre system itself collapsed as a functioning institution by the mid-fourteenth century, so chapiters as active legal instruments have an effectively bounded date range. Sources using the term after roughly 1350 are almost certainly retrospective or treatise-based rather than records of live proceedings.
Historical Dictionary Support
Burrill's treatment is the most detailed among standard law dictionaries and correctly identifies both the procedural function (summary of matters for inquiry) and the documentary chain: delivered by the king, used to direct justices, correlated with the Statute of Westminster I. Burrill's entry appears to have been cut off in the available text but opens the standard account reliably.
Webster's 1913 — drawing on Jacob's Law Dictionary — records the legal sense accurately but briefly, noting that the term was "also called articles." This equivalence is useful but slightly imprecise, as discussed under Common Confusion above.
Wiktionary's entry correctly gives all three senses (obsolete chapter, architectural capital, legal summary) and aligns with Burrill on the legal definition.
None of the available dictionary sources engage with the eyre system in sufficient depth to explain why chapiters mattered procedurally — that is, how they shaped what crimes and matters could be presented and how the list of capitula evolved across different eyres. Researchers needing that depth should move from the dictionary sources to the treatise literature (Britton, Fleta) and to scholarship on the eyre, where the content and variation of chapiter lists receives fuller treatment.
Jurisdictional Note
The chapiter is exclusively an institution of English law, tied to the specific machinery of royal itinerant justice in medieval England. It has no recognized equivalent in Scots, Irish, or colonial American legal practice. Researchers working in those jurisdictions will not encounter the term as an operative legal instrument.
