Definition
In Roman and medieval civil law, the referendarius was an imperial officer responsible for managing the flow of petitions and causes to the emperor. The role had three principal functions: receiving petitions from subjects, presenting those petitions to the emperor in orderly sequence, and communicating the emperor's responses back to petitioners. The office was essentially that of a gatekeeper and intermediary in the imperial administrative process — a formalized channel between the public and sovereign authority.
Why It Matters in Research
This term appears almost exclusively in historical legal materials dealing with Roman civil law, medieval continental administration, or the transmission of civil law concepts into early common law writing. Researchers will encounter it chiefly in treatises and commentaries that draw on the Corpus Juris Civilis or on glossators and post-glossators who annotated that tradition.
The principal research traps are two. First, the term is easily confused with similar-sounding offices in different administrative traditions — the medieval chancery systems of England and the Holy Roman Empire each had their own petition-handling officers, and writers sometimes used referendarius loosely to describe analogous roles that were not strictly identical to the Roman original. Second, Burrill's entry contains what appears to be a transcription or typesetting error: the definition breaks off mid-phrase ("through cords. An acquittance or acknowledgment of renouncing all future claim") before recovering to describe the office correctly. Researchers relying on Burrill should treat that entry with care, as the interpolated text belongs to a different entry entirely and does not define referendarius.
Because the term is drawn from Latin civil law sources, researchers pursuing it will need to work through the civilian tradition — Vicat's Vocabularium Juris Utriusque and Calvin's Lexicon Juridicum, both cited by Black's, are the primary historical reference points. Neither is digitized in widely accessible form, and both are in Latin. Law Mind corpus searches for referendarius will yield more results in treatises on Roman law, ecclesiastical law, and comparative legal history than in common law materials.
The office matters to legal historians tracing how petition processes and administrative intermediaries evolved from Roman imperial practice into medieval European governance, and eventually influenced concepts of administrative due process and access to sovereign authority.
Historical Dictionary Support
Black's first and second editions are in near-complete agreement, differing only in the addition of the word "An" at the start of the second edition's definition — a minor editorial cleanup that carries no substantive difference. Both editions cite Vicat and Calvin as authority without quotation, treating the office as settled civilian learning.
Burrill's entry is the most problematic of the three. It correctly identifies the term as Latin and situates it in "civil and mediæval law," and its core description — an officer through whom petitions to the emperor were presented or to whom they were referred — is consistent with Black's. However, the entry is visibly corrupted, containing interpolated text from what is almost certainly an adjacent entry on release or acquittance. This is a known hazard with Burrill's, where typesetting errors occasionally produced merged entries. The substantive content that survives is consistent with the other sources.
No source provides meaningful detail on the internal organization of the office, its relationship to other imperial officials, or its evolution across different periods of Roman administration. Historical dictionaries treat referendarius as a minor definitional entry rather than a developed concept, and none engages with the medieval adaptations of the role. Researchers needing more than the bare definition must go beyond these dictionaries to specialized histories of Roman and Byzantine administration.
