Definition
In old English law, an adjective meaning "of the value or price of a farthing," or more precisely, equivalent to one quarter of the smallest common monetary unit in use. The term derives from quadrans, the Latin word for a quarter or farthing. Its primary recorded usage is in the phrase panis quadrantalis — the farthing loaf — denoting the standard loaf of bread whose price was fixed at one farthing under the Assize of Bread, the medieval regulatory scheme governing the weight and price of bread in relation to the market price of grain.
The term appears in Fleta (lib. 2, c. 9), a late thirteenth-century English legal treatise, in the context of the Assize of Bread. The corresponding passage in Britton (c. 30), a roughly contemporaneous legal compilation, uses the vernacular word ferlinges rather than quadrantalis, pointing to the same concept through the Anglo-French equivalent. The two terms are functionally parallel and can be treated as cognates for research purposes, with quadrantalis being the Latinate form and ferlinges the vernacular.

Common Confusion
QUADRANTALIS vs. QUADRANTATA TERRAE: These are distinct terms sharing the Latin root quadrans (a quarter). Quadrantalis is an adjective describing monetary value — specifically, the worth of a farthing — and appears in the context of bread pricing under the Assize of Bread. Quadrantata terrae is a noun phrase referring to a unit of land area, roughly the fourth part of an acre (though historical sources conflict on the precise measurement). A researcher encountering either term should confirm which concept is at issue before interpreting the document.

Why It Matters in Research
This is a narrow, highly specialized term with limited but precise utility. Researchers are unlikely to encounter quadrantalis outside of medieval English legal treatises and documents touching on the Assize of Bread or related price-regulation mechanisms. Its value is almost entirely contextual: when the term appears, it signals that a document is engaging with the Assize framework — one of the earliest examples of state-regulated commodity pricing in English legal history.
Several traps await researchers working with this term:
First, Burrill notes explicitly that neither Spelman nor Cowell includes quadrantalis as a headword, meaning that two of the major historical Latin legal dictionaries offer no direct entry. A researcher relying solely on Spelman's Glossarium Archaiologicum or Cowell's Interpreter will find no definition and may mistake the word for an error or anomaly in the source text.
Second, the related term quadrantata terrae (the fourth part of an acre, according to Cowell, though Spelman's definition diverges) is distinct from quadrantalis. One concerns land measurement; the other concerns monetary value and bread pricing. The shared Latin root quadrans creates a surface similarity that can mislead. A researcher indexing medieval documents by root word may conflate references to land division with references to bread regulation.
Third, the parallel between quadrantalis (Fleta) and ferlinges (Britton) is a useful interpretive key: when reading across the two treatises on the same legal subject, the different vocabulary reflects the bilingual legal culture of medieval England rather than any substantive difference in meaning. Researchers comparing passages in Fleta and Britton should treat these as equivalent terms.
Finally, because this term is embedded in the Assize of Bread tradition, it connects to a broader regulatory corpus that extends from the thirteenth century through later statutory iterations. Research on medieval food regulation, market controls, or the history of administrative law in England will benefit from recognizing this term as a marker for that tradition.

Historical Dictionary Support
Burrill's Law Dictionary provides the only direct entry among the Law Mind shelf sources. Burrill defines quadrantalis as meaning "of the value or price of a quarter or farthing" and anchors the definition in Fleta, while cross-referencing the parallel Britton passage using ferlinges. Burrill also notes that Spelman and Cowell do not cover the term — an unusual editorial observation that itself carries research value, confirming the term's peripheral status even within historical legal lexicography.
The entry in Burrill is immediately followed by a separate entry for quadrantata terrae, which Burrill begins to define (citing Cowell's "fourth part of an acre") but notes that Spelman's definition diverges — the entry in the source material appears truncated. These two entries are related only by their shared Latin root and should not be treated as aspects of a single concept.
No additional coverage is available from the other Law Mind shelf sources for this term. Researchers requiring fuller treatment of the Assize of Bread context should consult Fleta and Britton directly, as well as secondary literature on medieval English market regulation.

Jurisdictional Note
Quadrantalis is specific to medieval English law and the Assize of Bread regime. It has no known parallel usage in Scots law, canon law, or civil law traditions. The term is not operative in any modern jurisdiction.
