Definition
A Latin term appearing in old pleading, meaning a box. In legal usage, pixis referred to a physical container — most commonly a box used to hold deeds, title documents, and other muniments of title. The term appears in early common law pleadings as a formal descriptor when identifying the subject matter of an action, particularly in trover, where the precise Latin designation of the object allegedly converted was required.
Common Confusion
Researchers should not conflate pixis with the ecclesiastical pyx or pyxis, which refers to a liturgical vessel used in Christian worship. Though the Latin root is shared and the words are cognates, the legal pleading term pixis refers exclusively to a secular box — a container for personal property or legal documents — and has no religious connotation in the case law context where it appears.
Why It Matters in Research
Pixis is an archaic pleading term with no living legal usage. Researchers will encounter it only in pre-modern English case reports, particularly those from the early seventeenth century and earlier, where Latin pleading forms were standard. Its significance is almost entirely contextual: the term identifies the physical object at issue in an action, and its appearance in a case report signals that the dispute likely concerned personal property of some kind — here, a container and its contents.
The most important navigational point is that pixis could denote different types of boxes depending on context. In some instances it refers simply to a box as a chattel subject to trover or detinue. In others — as Burrill notes with reference to Latch 195 — it specifically designates a deed box or muniment chest, which carries greater legal weight: a box used to store title documents was not merely a piece of personal property but a repository of evidence of ownership and right. Confusion between these two senses could affect how a researcher interprets the underlying dispute.
Researchers working in early English case reports should also note that Latin object descriptions in pleadings were technical requirements, and minor variations in terminology could have procedural consequences. When a pleading identified the subject of an action in Latin, the accuracy of that description was sometimes contested. Understanding that pixis means specifically a box — and not a chest, trunk, or coffer — may matter when comparing pleadings or tracing procedural objections in the reports.
Because pixis appears in Law French and Latin pleading contexts, it will often appear alongside Anglicè (meaning "in English"), which signals that the reporter or pleader is translating the Latin term for clarity. This convention is illustrated directly in Burrill's example from Croke's Jacobean reports: "Trover was brought de una pixide, Anglicè, a box full of bands." The phrase de una pixide is the ablative form, consistent with the pleading convention of describing the object of the action in the ablative case.
Historical Dictionary Support
Burrill's Law Dictionary provides the only substantive historical legal definition. His entry is brief but precise, drawing on two sources: Croke's Jacobean reports (Cro. Jac. 664) for the general meaning of a box as chattel, and Latch's reports (Latch 195) for the more specific meaning of a deed box or muniment box. This dual citation is useful because it establishes that the term carried both a generic and a specialized sense in legal practice.
Burrill does not explore the term's ecclesiastical dimensions, though pixis (and its variant pyx or pyxis) appears in ecclesiastical and liturgical contexts to mean the vessel containing consecrated hosts. That meaning is entirely absent from the legal pleading context and should not be imported into legal research.
No other historical legal dictionaries in the Law Mind corpus provide entries for this term, making Burrill the controlling source.
