Definition
Cellarius is a Latin term appearing in historical legal and diplomatic contexts referring to a steward, butler, or keeper of stores — an officer charged with the custody and management of provisions, supplies, or valuables held in a cellar or storehouse. In Roman and ecclesiastical usage, the cellarius was a household or institutional officer responsible for maintaining and accounting for goods held in trust or in storage on behalf of a principal.
In a legal context, the term carries significance primarily in the law of bailment, agency, and fiduciary accountability, where the cellarius occupied a position of custodial responsibility analogous to a modern warehouseman or steward. The officer held property not as owner but as custodian, with attendant duties of care and account.

Common Language
Modern common usage (Wiktionary): Not a recognized entry in modern English dictionaries; effectively a historical or archaic term with no current common usage.
Historical common usage (Webster's 1913): Not listed as a standalone entry; the root term "cellar" (Latin: cellarium) referred to an underground storage chamber, with "cellarer" appearing in ecclesiastical contexts as the monk or officer responsible for provisions.
Editorial note: Because the term has no surviving common English usage, the gap between common and legal meaning is not a live research problem. The difficulty is the opposite — researchers may not recognize the term at all when encountered in historical legal documents or ecclesiastical records.

Why It Matters in Research
Researchers working in medieval legal history, ecclesiastical law, or Roman civil law sources will encounter cellarius in documents governing institutional household management, monastic governance, and the accountability of officers holding property for others. The term is particularly relevant in:
— **Monastic and ecclesiastical records**: The cellarius or cellarer of a monastery was a recognized legal officer with duties and liabilities that courts and canonical tribunals treated as cognate to those of a trustee or bailiff. Disputes over accounts, shortfalls, or misappropriation of stores appear in ecclesiastical court records under this designation.
— **Feudal household law**: In manorial and feudal contexts, the cellarius appears as a domestic officer of the lord's household. His accountability for stores connects to early doctrines of account and the writ of account (actio de computo), making the term relevant to the history of accounting actions and fiduciary duty.
— **Roman law sources**: Civil law commentators treating the actio depositi, the actio mandati, or the obligations of a procurator may use cellarius as an illustrative figure. Researchers using Justinian's Digest or Institutes in translation may encounter the term in glosses or commentary.
**Trap for researchers**: Because Bouvier's Law Dictionary does not include a standalone entry for cellarius (the source material provided under this heading appears to be a misfile — the text given is in fact Bouvier's entry for REFERENDUM, not cellarius), researchers should treat the absence of a definition in common American legal dictionaries as a navigational signal to consult civil law dictionaries, ecclesiastical law glossaries, and medieval Latin legal lexicons. Du Cange's Glossarium Mediae et Infimae Latinitatis is the authoritative reference for cellarius in its historical legal senses. Black's Law Dictionary editions through the mid-twentieth century likewise do not carry this term, reflecting its confinement to civilian and canon law traditions rather than the common law.
**Corpus connection**: In the Law Mind corpus, cellarius is most likely to appear as a term of art in materials touching Roman law foundations, ecclesiastical governance, or comparative law scholarship rather than in common law case reporters.

Historical Dictionary Support
Bouvier's Law Dictionary does not provide a usable entry for cellarius. The source material transmitted under this heading is Bouvier's definition of REFERENDUM — a distinct term concerning the authority of diplomatic agents — and contains no content relevant to cellarius. This is noted here as a source integrity flag for corpus researchers: the indexing or transmission of the Bouvier text appears to have produced a mismatch between the headword and the definition supplied.
In the absence of Bouvier's treatment, the historical dictionary record for cellarius in English-language legal literature is sparse. The term does not appear in Rastell's early legal glossaries or in Termes de la Ley. Its natural home is in Spelman's Glossarium Archaiologicum and Du Cange, both of which treat it as a civil and ecclesiastical law office. The Corpus Juris Canonici and commentators on Benedictine Rule address the cellarius as an officer with specific legal duties, and canonical scholarship from the twelfth century onward treated his obligations in terms recognizable to a lawyer as custodial accountability.
What historical dictionaries collectively miss is any systematic analysis of the cellarius as a link in the chain from Roman custodial liability to medieval trust and account doctrine — a gap that comparative legal historians have only partially filled.

Jurisdictional Note
Cellarius as a legal term of art has no operative role in modern Anglo-American common law jurisdictions. Its significance is confined to historical research in civil law, canon law, and comparative legal history. Researchers in civilian jurisdictions (France, Italy, Spain, and their former territories) may encounter derivative terms in early modern legal sources.
