Definition
A historical feudal tax or due levied on horned cattle. Hornagium is an early English fiscal term designating a payment assessed on the owner or keeper of horned beasts, typically owed to a lord or forest authority. The term is functionally synonymous with HORNGELD (or HORNEGELD), which Rapalje & Lawrence treat as the primary entry, directing readers there from hornagium. In its forest law context, the charge was among the various tolls and exactions imposed on those who pastured livestock within or near royal forests and common lands.
Why It Matters in Research
Hornagium is an archaic term that will surface almost exclusively in pre-modern English sources — medieval charters, manorial records, forest eyre proceedings, and early institutional histories. Researchers should be aware of two navigational realities.
First, Rapalje & Lawrence cross-reference hornagium to horngeld without defining it independently. Any corpus search that terminates at hornagium will miss the substantive entry. Always expand searches to include horngeld, hornegeld, and horn-geld, which appear across historical sources in variant spellings.
Second, the term sits within a cluster of closely related forest and manorial dues — pannage (for pigs), agistment (for general livestock pasturing fees), and cheminage (for passage through forests) — that operated alongside hornagium in historical land and forest law. A document referencing hornagium may be concerned with any of these overlapping obligations, and understanding the broader system is necessary to interpret individual references accurately.
Researchers working with Scotch law sources should exercise particular care: the adjacent entry for HORNING, LETTERS OF in Rapalje & Lawrence refers to a wholly distinct Scottish legal instrument — a warrant for compelling payment or performance — and shares only superficial phonetic similarity with hornagium. These are unrelated concepts.
Historical Dictionary Support
Rapalje & Lawrence provide no independent definition of hornagium, treating it as a pure cross-reference to horngeld/hornegeld, which they describe as "a forest-tax paid for horned beasts." This is consistent with the term's appearance in institutional histories of English law, where it designates a customary charge on horned livestock as part of the broader apparatus of forest law and manorial administration. The Rapalje & Lawrence entry reflects the convention of mid-nineteenth-century legal lexicography, which collected feudal and forest law terms largely from Spelman, Cowell, and similar antiquarian compilations rather than from active legal practice — a reminder that such entries describe historical institutions, not living legal obligations. No modern legal dictionary treats hornagium as a term of current operative significance.
Jurisdictional Note
Hornagium is exclusively a historical English (and, in variant form, occasionally Scottish) legal term. It has no counterpart in American law and does not appear as an operative concept in any modern common law jurisdiction.
