Definition
A nosocomus was, in the civil law, a person charged with the care and administration of a hospital or infirmary. The term denotes a hospital keeper or superintendent — an individual responsible for the management of an institution dedicated to the care of the sick. The role was recognized in Roman law as a position of sufficient legal consequence to warrant treatment in the Justinianic codes.

Why It Matters in Research
This term appears almost exclusively in civil law contexts drawn from the Corpus Juris Civilis, specifically the Codex and the Novels of Justinian. Researchers encountering nosocomus in primary or secondary sources should understand it as a term of Roman and Byzantine institutional law, not a term that migrated meaningfully into common law systems. It is unlikely to appear in English-language case law or statutes.
The primary research value of this term is contextual: when reading treatises or commentaries on the civil law tradition — particularly those dealing with charitable institutions, pious foundations, or ecclesiastical property — nosocomus may appear as a technical designation for administrators of hospitals that were often church-affiliated. In late Roman and Byzantine law, hospitals (nosocomia) frequently operated under episcopal oversight, and the nosocomus occupied a recognized administrative and quasi-fiduciary role within that structure.
Researchers working in the history of charitable trusts, ecclesiastical law, or the civilian tradition of institutional management will find this term relevant to understanding the precursors of modern trustee and administrator concepts. The connection between Roman hospital administration and later canon law treatment of charitable foundations is a documented line of development, and nosocomus sits at that intersection.
Do not expect this term in digests of English equity or common law. Its natural habitat is in civilian treatises, canon law commentaries, and historical scholarship on Roman or Byzantine administrative institutions.

Historical Dictionary Support
Burrill's Law Dictionary provides the sole historical legal dictionary entry located in the Law Mind corpus. Burrill correctly identifies the term as Greco-Latin, traces its Greek components (nosos, disease; komein, to take care), defines it as one who had the care of a hospital under the civil law, and cites two specific locations in the Justinianic corpus: Codex 3.1.46.3 and Novella 7, epilogue. These citations are consistent with known Justinianic provisions addressing charitable and ecclesiastical institutions.
No entry for this term appears in other major historical legal dictionaries in the common law tradition, which is expected given the term's exclusive civilian provenance. The absence from sources such as Black's or Bouvier's reflects not an oversight but the term's irrelevance to common law practice. Burrill's inclusion is consistent with his broader coverage of civil law terminology, reflecting the nineteenth-century American legal scholar's interest in the civilian tradition as background to equity and ecclesiastical law.
The definition Burrill provides is accurate as far as it goes, though it does not explore the institutional or ecclesiastical dimensions of the role. The nosocomus in late Roman law was not merely a caretaker in a colloquial sense but a recognized administrator of what functioned as a charitable institution — a nuance that matters when tracing the historical development of fiduciary and trust-like obligations in civilian systems.

Jurisdictional Note
This term has no operative significance in modern common law jurisdictions. It belongs to Roman and Byzantine civil law and survives in legal scholarship and historical analysis rather than in living legal systems. Researchers in civil law countries with deep Roman law foundations (e.g., Italy, Spain, France) may encounter it in historical legal texts, but it carries no current doctrinal weight in any jurisdiction.
