Definition
In Roman law, a robber or plunderer. The term denotes one who takes property by force or open violence, as distinguished from a thief (*fur*), who takes by stealth. The praedo acted openly and with the use or threat of force; the distinction carried legal significance in Roman private law because different remedies and condemnations applied depending on how the taking occurred.
Note on spelling: The headword "Prjedo" appearing in some supplemental editions of Black's is a typographical variant of the classical Latin *praedo*. Both forms refer to the same Roman law concept.
Common Confusion
PRAEDO vs. FUR: Roman law drew a sharp line between the praedo (robber, acting by open force) and the fur (thief, acting by concealment or stealth). This distinction is not merely semantic — Roman jurists treated them under separate heads of liability, and the remedies available to victims differed accordingly. Researchers encountering either term in translated Roman law sources or civil law commentary should not treat them as interchangeable.
Why It Matters in Research
This term will appear almost exclusively in sources dealing with Roman private law, civil law commentary, or early English legal writing that drew on Roman sources. It has no operative meaning in modern common law jurisdictions. Researchers should treat it as a glossary term when encountered in translation of the Digest or Corpus Juris Civilis, or in civilian treatises.
The Digest reference cited in Black's — Digest 50, 17, 126 — falls within the title *De diversis regulis juris antiqui* (On Various Rules of Ancient Law), a collection of general maxims drawn from classical jurists. Researchers working with the Digest should be aware that Book 50, Title 17 is a compendium of legal aphorisms rather than a doctrinal treatment; the reference locates the word in a maxim context, not a developed legal rule.
In civil law jurisdictions and in historical common law scholarship drawing on Roman sources, the distinction between force-based taking and stealth-based taking resurfaced in various forms — including early English distinctions between robbery and larceny. Researchers tracing the historical roots of robbery as a distinct offense from theft may find the Roman praedo/fur distinction a useful conceptual anchor, though the doctrinal lineage through English law runs through Norman and canonical sources rather than directly from Roman law.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed., Supplemental) defines praedo tersely as "a robber" and directs the reader to Digest 50, 17, 126. This is the extent of the historical dictionary treatment. No other standard historical law dictionaries in the Law Mind corpus — including Bouvier or Burrill — carry a developed entry for this term, reflecting its status as a Roman law term of art without significant transplantation into Anglo-American legal vocabulary.
The brevity of the Black's entry is itself informative: the editors included it for completeness in glossing Roman sources, not because the term had acquired independent significance in American or English legal practice.
Jurisdictional Note
Praedo is a term of Roman law with no direct operative equivalent in modern common law. It may appear in Louisiana, Quebec, or other mixed civil law jurisdictions in historical sources or scholarly commentary, but it carries no statutory or case-law significance in any current jurisdiction.
