Definition
A Latin term from the civil law tradition meaning a fire or conflagration. *Incendium* appears in Roman legal texts principally in two contexts: as a factual event giving rise to legal consequences (particularly liability and obligations), and as a basis for certain defenses or claims relating to loss. The term is not a term of art in modern common law systems but persists in legal scholarship and historical legal analysis, especially in discussions of Roman law, the Digest, and early civil law doctrine.

Common Confusion
*Incendium* should not be confused with the modern common law offense of arson or with the tort of negligent fire-setting, though the factual subject matter overlaps. *Incendium* in its Roman law context is primarily a descriptive legal term for a fire event, not a crime or cause of action in itself. The criminal dimension of deliberate fire-setting in Roman law was addressed under separate headings. Researchers encountering *incendium* in civil law sources should not assume it maps directly onto any single modern legal category.

Why It Matters in Research
This term surfaces almost exclusively in Roman law sources and in early civil law treatises and commentaries drawing on the Digest and the Codex. Researchers working in those materials need to recognize two things.
First, *incendium* functions as a trigger event in Roman legal doctrine. The maxim *incendium ære alieno non exuit debitorem* — a fire does not release a debtor from his debt — is the most frequently cited application. This principle, drawn from the Codex (Cod. 4.2.11), established that destruction of property by fire did not extinguish a debtor's personal obligation. Understanding this doctrinal use helps researchers trace how Roman law handled force majeure and impossibility of performance, themes that carried forward into later civil law systems and inform modern debates about supervening impossibility and discharge of contract.
Second, the Digest title where *incendium* appears prominently (Dig. 47.9) groups fire together with shipwreck, ruina (collapse), and naufragium as occasions for specific protections and liabilities, including rules against those who looted property during such disasters. Researchers should consult that broader title context rather than reading isolated incendium references in isolation. The cluster of terms in Dig. 47.9 forms a coherent doctrinal unit.
For Law Mind corpus researchers: citations to *incendium* in secondary sources often reference these Digest and Codex passages without full quotation. When tracing the maxim about debtors and fire, the Codex 4.2.11 is the primary locus; the Digest materials elaborate the surrounding liabilities. Early modern civil law commentators — including those in the ius commune tradition — returned to this maxim frequently in discussions of contractual obligation and risk allocation. A researcher who encounters *incendium* in a seventeenth- or eighteenth-century civil law treatise is likely reading a mediated version of the Roman source, not the original, and should verify what gloss the later writer has added.

Historical Dictionary Support
Burrill's Law Dictionary provides the essential core: the term is Latin, derives from *incendere* (to burn), belongs to the civil law, and means a fire or conflagration. Burrill supplies both the definitional statement and the two key source citations — Dig. 47.9 and Cod. 4.2.11 — along with the maxim in full. This is representative of how nineteenth-century Anglo-American legal dictionaries handled Roman law terms: accurate identification of the civilian source and the governing maxim, without elaboration of surrounding doctrine.
What Burrill does not provide is the broader Digest context in which *incendium* figures — specifically, the elaborate Roman protections against opportunistic looting and exploitation during fires, which formed a significant part of the Dig. 47.9 title. Nor does Burrill situate the debtor-fire maxim within the larger Roman discussion of where risk of loss falls in obligational relationships. For research purposes, Burrill's entry is a reliable starting point and a trustworthy citation guide, but it is a compass bearing rather than a map.
No other dictionary source in the current corpus treats this term. Researchers requiring fuller treatment should consult standard Roman law reference works and editions of the Digest directly.

Jurisdictional Note
*Incendium* as a term has no operative role in modern common law jurisdictions. In jurisdictions with civil law heritage — particularly those tracing doctrinal lineage through the ius commune — the underlying principles associated with *incendium* (risk allocation, non-discharge of obligations by fire loss) have been absorbed into general contract and obligations doctrine and no longer travel under the Roman label.
