Definition
In Roman law, missilia were gifts or gratuities thrown by Roman magistrates — particularly praetors and consuls — into crowds of people gathered at public events. The term describes the practice of scattering tokens, coins, or small presents among the populace as an expression of largesse. The gifts became the property of whoever retrieved them, acquired by occupancy rather than by any preceding ownership claim.
The legal significance of missilia lies primarily in the Roman law of property acquisition: items thrown to a crowd were understood to pass from the giver's ownership at the moment of throwing, vesting in whichever individual took possession. Justinian's Institutes treat missilia as an illustration of acquisition by occupancy (occupatio), the principle that ownerless or abandoned things may be claimed by the first possessor.

Common Language
Modern common usage (Wiktionary): "Missilia" has no standard modern English entry. The singular form "missile" derives from the same Latin root and refers to any object or weapon propelled through the air; in modern use, most commonly a self-propelled weapon.
Historical common usage (Webster's 1913): Webster's does not carry "missilia" as an English entry. "Missile" is listed as an adjective meaning "capable of being thrown" and as a noun meaning "a weapon thrown or projected."
The legal term "missilia" belongs to Roman legal vocabulary and has no live English legal counterpart. The shared Latin root with "missile" is linguistically interesting but legally irrelevant — missilia denotes gifts distributed by scattering, not weapons.

Why It Matters in Research
Missilia appears almost exclusively in discussions of Roman property law, specifically the doctrine of occupatio. Researchers will encounter the term most often in treatises and commentaries working through the Institutes of Justinian (Inst. 2.1.45), which uses missilia as a textbook example of how ownership of things passes to the first taker when a prior owner deliberately relinquishes control by scattering goods among a crowd.
The term has virtually no independent common law or modern statutory life. Its presence in Black's, Bouvier's, and Burrill's reflects the nineteenth-century American legal dictionary tradition of comprehensively cataloguing Roman and civil law terminology as background to property doctrine. Researchers working in civil law jurisdictions, comparative property law, or the history of property concepts will find the term more substantively useful than those working in purely common law contexts.
One practical research trap: do not conflate the property-law treatment of missilia with later discussions of "gifts to the public" or charitable distributions in modern law. The Roman doctrine turns on occupancy and the intentional abandonment of ownership — a framework that does not map cleanly onto modern gift law, which requires delivery and acceptance in ways that missilia deliberately bypassed.
Burrill's entry is the most useful of the three for researchers because it supplies the Latin derivation (mittere, to send or throw) and cross-references the related term MISSUS, which travels in entirely different doctrinal territory — ecclesiastical and administrative law — despite sharing a root.

Historical Dictionary Support
All three source dictionaries agree on the substance: missilia are gifts thrown among the people by Roman magistrates, and all three anchor the definition to Institutes 2.1.45. The entries are essentially uniform, suggesting the definition was stable across the nineteenth-century lexicographic tradition and drawn from a common civilian source.
Burrill's adds the most scholarly texture, providing the Latin derivation and noting the plural/singular relationship. Black's entry contains an apparent typographical artifact — the phrase "plication, and is called a 'mistake of law.' 12" appears mid-entry, almost certainly a printing or OCR error from an adjacent entry bleeding into the missilia text. Researchers using digitized versions of Black's should be aware of this corruption.
None of the three dictionaries develop the property law doctrine beyond the bare definition. For the substantive legal analysis — how missilia illustrated occupatio, how Justinian's jurists reasoned about the moment of ownership transfer, and how later civilians applied the principle — researchers must go to the Institutes directly or to civilian property treatises. The dictionary entries function as pointers, not as doctrine.
