Definition
Questores parricidii (singular: quaestor parricidii) were magistrates of early Roman law charged with investigating and prosecuting cases of parricide and murder. The office was held by two officials appointed by the comitia — the Roman popular assembly — functioning as a standing commission for the most serious category of criminal offense. The term combines questores (investigators or inquirers) with parricidii (of parricide), reflecting the office's original and defining purpose. Probably appointed on an annual basis, these officers represented one of the earliest formal mechanisms in Roman law for public prosecution of homicide.
Why It Matters in Research
This term appears almost exclusively in Roman law scholarship and comparative legal history. Researchers encountering questores parricidii in primary or secondary sources should understand several navigational points.
First, the office is historically significant as an early instance of publicly appointed criminal investigators — a precursor to the later, broader quaestorship that became a standard Roman magistracy. The questores parricidii should not be conflated with the later quaestors (quaestores) of the Roman Republic and Empire, whose functions expanded well beyond criminal prosecution to include treasury administration and other public duties. The parricidii designation marks a narrower, earlier, and more specialized office.
Second, the scope of the office is analytically important: despite the literal meaning of parricidii (parricide, the killing of a father or near kinsman), Black's notes that the commission's jurisdiction extended to murder generally — not just parricide in the narrower modern sense. Researchers working on the history of criminal law, the development of the parricidium concept, or the evolution of homicide categories in Roman law should be attentive to this broader scope.
Third, the institutional mechanism — appointment by comitia as a quasi-commission — is relevant to comparative constitutional history, particularly for scholars tracing the development of prosecutorial function, delegation of criminal jurisdiction, and the separation of investigation from adjudication.
The Law Mind corpus may contain this term in encyclopedia entries on Roman law, comparative criminal law history, or discussions of the origins of public prosecution. Cross-referencing with entries on the broader quaestorship and on parricidium will generally be necessary for a complete picture.
Historical Dictionary Support
Black's Law Dictionary provides the sole historical dictionary entry for this term, drawing on Sir Henry Maine's Ancient Law (1861) at page 370 as its primary scholarly support. Maine's work remains the foundational English-language treatment of early Roman legal institutions and is the authoritative secondary source for this office.
Black's characterization is terse but accurate in outline: two officers, appointed by the comitia, constituting a kind of commission for parricide and murder cases, probably serving annual terms. The entry does not explore the deeper scholarly debate about whether the questores parricidii were among the very earliest Roman magistracies, predating much of the formal Republican constitutional structure — a point Maine himself addresses with more nuance in the cited passage. Researchers should go directly to Maine for the fuller institutional and historical context that Black's necessarily compresses.
No other historical dictionary on the Law Mind shelf (not Bouvier, not Wharton, not Burrill) appears to provide a substantive entry for this term, reflecting both its specialized character and the relative neglect of Roman institutional history in American legal dictionary tradition. The absence of an entry in Bouvier is worth noting for researchers who might expect coverage there of Roman law terms.
Jurisdictional Note
This term has no operative jurisdiction in any modern legal system. It is a term of Roman legal history relevant to comparative law scholarship, legal history, and the history of criminal procedure. No contemporary common law or civil law jurisdiction recognizes or applies the office.
