Definition
Vicinetum (Law Latin) is a term from old English law denoting the neighborhood, vicinage, or venue from which jurors were to be drawn for trial. It refers to the geographic community — originally understood as the vill or adjacent parts, later as the hundred, and ultimately as the county — whose inhabitants were presumed to have local knowledge of the facts and parties at issue in a legal proceeding.
The term operates at the intersection of two ideas that were once fused in English law but later diverged: (1) the locality from which jurors were summoned, and (2) the place where trial was to be held. In medieval practice, these were effectively the same — jurors were neighbors who knew the facts firsthand, and the trial occurred among them. As the jury evolved from a body of witnesses into a body of impartial fact-finders, the procedural significance of vicinetum shifted toward the latter — venue — while the presumption of local knowledge receded.
The maxim associated with the term captures its original rationale: Vicini viciniora praesumuntur scire — persons living in the neighborhood are presumed to know the neighborhood.
Common Confusion
Vicinetum, vicinage, visne, and venue are historically overlapping terms that modern researchers frequently treat as interchangeable, but they carry distinct technical emphases. Vicinetum is the broadest Latin form, denoting the neighborhood or locality itself. Vicinage is the anglicized equivalent, used more commonly in later common law practice and surviving into American constitutional discourse (the Sixth Amendment's "vicinage" clause). Visne or visnet (also spelled visinetum or visinetus) is a variant form referring specifically to the jury-panel drawn from the neighborhood. Venue is the modern procedural successor concept, stripped of the presumed-knowledge rationale and concerned purely with the geographic location of trial. Conflating these terms in historical sources will obscure the evolution of jury theory.
Why It Matters in Research
Researchers working in medieval and early modern English legal sources will encounter vicinetum as the operative term for what later becomes the venue doctrine. Three navigational points matter:
First, the geographic scope of the term shifted across time. Burrill's entry is the most precise on this point: vicinetum was anciently understood as the same vill or adjacent parts, then the hundred, and finally the county. A source using the term in its early medieval sense is describing a much narrower geographic community than the same term in later Tudor or Stuart practice. Failure to account for this shift produces anachronistic readings.
Second, the maxim Vicini viciniora praesumuntur scire (cited to Coke's Fourth Institutes) is the doctrinal engine behind the original jury model. The neighborhood was the source of jurors precisely because neighbors were presumed to know local facts. When researching the transition from the self-informing jury to the modern evidence-based jury, the vicinetum concept marks the earlier paradigm. Sources citing this maxim approvingly in later periods may be invoking an increasingly fictional presumption.
Third, the connection to Magna Carta (Chapter 14 in Burrill's citation, though chapter numbering varies across versions) gives vicinetum constitutional weight in English legal history. Researchers tracing the deep lineage of jury-of-the-vicinage rights — including American Sixth Amendment scholarship — should trace back through vicinage to vicinetum to understand the original geographic and communal logic.
The variant spellings (visinetum, visinetus, visnet, visne) are common in manuscript and early printed sources. A search on the single spelling vicinetum will miss a substantial portion of the corpus. Build searches to capture the full variant family.
Historical Dictionary Support
Black's (1st and 2nd editions) are consistent with each other and provide the core definition — neighborhood, vicinage, venue — along with the Coke maxim. The 2nd edition repeats the 1st with only minor textual variation and no substantive expansion.
Burrill's entry is substantially richer and more historically precise. It supplies the etymological grounding (from Latin vicinus, near, adjacent), the Magna Carta reference, the Spelman gloss (locus quem vicini habitant — the place which neighbors inhabited), and — critically — the account of geographic scope shifting from vill to hundred to county. Burrill also supplies the variant form family (visinetum, visinetus, visnet), which Black's omits entirely.
What neither Black's nor Burrill's addresses is the doctrinal evolution from the self-informing jury to the modern jury, and how that evolution hollowed out the functional rationale for drawing jurors from the vicinetum. Historical dictionaries treat the term descriptively but do not flag the theoretical transformation embedded in it. Researchers should not assume that later sources using vicinetum or vicinage are invoking the same underlying jury theory as the earlier sources.
Jurisdictional Note
Vicinetum is a term of old English law with no direct survival in modern American or English statutory usage. Its legacy in American law runs through the Sixth Amendment's guarantee of trial "by an impartial jury of the State and district wherein the crime shall have been committed" — language that preserves the vicinage concept in modified form. English law addressed the same concerns through venue rules that abandoned the neighborhood-knowledge rationale. Researchers working in American constitutional history will find the term most relevant to originalist and historical arguments about the jury-of-the-vicinage clause.
