Definition
A Latin term from old English law meaning harnessed or tackled — specifically, equipped with gear or harness for work. The phrase *attilatus equus* denotes a horse furnished with its full working gear for cart or plough service, as distinguished from a horse kept for riding or other purposes. The term functioned as a descriptive qualifier in legal instruments, conveyances, and inventories where precision about the condition or working status of draught animals was legally material.
Why It Matters in Research
Researchers encountering this term will find it almost exclusively in medieval and early modern English legal documents — manorial records, conveyances of agricultural property, probate inventories, and pleadings involving the transfer or distress of livestock and farm equipment. The significance is practical: in agrarian legal contexts, whether a horse was *attilatus* — delivered or seized with its working harness — could affect the valuation of the animal, the completeness of a conveyance, and the validity of a distraint. A horse taken or granted with harness intact was a different legal subject than the animal alone.
Researchers should be cautious not to treat *attilatus* as a term of art with a fixed modern equivalent. It appears as a qualifier within Latin legal phrases rather than as a standalone legal category. When reading documents in Law Latin, pay attention to the accompanying noun and context: the term describes a condition of readiness for agricultural labor, not a separate class of property. Cross-reference with related terminology concerning agricultural tenures, villain services, and the legal treatment of *catalla* (chattels) in manorial and feudal instruments.
The term is rare enough that its appearance in a source is itself a signal: the document likely dates from the medieval period or is a learned compilation drawing on medieval English practice. Modern legal usage is nonexistent.
Historical Dictionary Support
Burrill's Law Dictionary provides the sole source entry, defining *attilatus* as "harnessed; tackled" and citing Cowell's *Interpreter* as authority. Burrill's entry is brief and descriptive, offering the core phrase *attilatus equus* as the operative example. The citation to Cowell places the term within the tradition of legal lexicography that drew heavily on manorial and agrarian Latin, where precise description of the working condition of animals carried legal weight in disputes over conveyance, distress, and tenure obligations.
No other shelf source addresses the term independently. Cowell's *Interpreter* (1607) is the underlying authority Burrill references, and that work itself belonged to a tradition of glossing law Latin terms found in English legal records. The historical dictionary record is thus thin but consistent: this is a technical descriptor from agricultural legal Latin with no contested meanings across the sources.
Jurisdictional Note
The term is specific to old English law and the Latin legal tradition of medieval and early modern England. It does not appear to have been transplanted into other common law jurisdictions as a term of art. Researchers working in Scottish, Irish, or colonial American records should treat any appearance as a borrowing from English legal Latin rather than as a term with independent local development.
