Definition
An archaic Latin term for a granary or storehouse — a structure used for the preservation and storage of grain. ORREUM is an orthographic variant of HORREUM, the more commonly encountered form in legal and historical texts. Both terms appear in Roman law and in medieval documents concerning agricultural property, landlord-tenant arrangements, and obligations relating to the storage and safekeeping of goods.
Common Confusion
Researchers should not confuse ORREUM with ORRERY (an astronomical model) or with any common English word sharing a similar appearance. The sole risk of confusion in legal research is treating ORREUM and HORREUM as different terms with different meanings. They are not. ORREUM is a spelling variant only; all substantive research should proceed under HORREUM.
Why It Matters in Research
ORREUM is a spelling variant that can cause researchers to miss relevant material if they search only under the standard form HORREUM. In manuscript and early printed legal sources, orthographic consistency was not guaranteed; scribal and typographic variation was common, particularly in the transmission of Latin terms through medieval intermediaries into early modern legal compilations. A researcher working through older digests, property records, or ecclesiastical documents related to agricultural holdings may encounter ORREUM without any cross-reference.
Bouvier directs readers to HORREUM without elaboration, which is the correct research path — the substantive legal content is housed under that headword. Burrill provides the more useful entry for the variant form itself, identifying it explicitly as an old form and directing the researcher accordingly. When either term appears in a historical document, the relevant legal context is almost always the physical structure and the obligations that attached to it: duties of care, liability for spoilage or loss, lease conditions, and tithe or render obligations tied to harvest storage in feudal and ecclesiastical settings.
Historical Dictionary Support
Burrill is the more informative source here. He treats ORREUM as a documented variant form deserving its own entry, confirming it is not a typographical error but a recognized spelling found in older sources. Bouvier dispenses with the variant entirely, cross-referencing only. Neither dictionary elaborates on the legal incidents of the storehouse itself under this headword — that content, including Roman law treatment of the horreum as a subject of locatio conductio and depositum, must be sought under HORREUM.
Neither source addresses the broader context of storage obligations in Roman law, where the horreum had a distinct commercial identity — operators of public horrea (warehouses) in Roman urban centers bore responsibilities analogous to modern warehousemen or bailees. That layer of legal meaning is largely absent from the common law dictionaries and reflects a gap in their Roman law coverage.
