Definition
In Roman civil law, a fullo (plural: fullones) was a fuller — a tradesperson who cleaned, thickened, or dressed cloth and garments for hire. The term appears in classical Roman legal sources primarily in the context of the contractual relationship established when a customer delivered garments to a fuller for processing at an agreed price. In this context, the fullo was the hired party under a locatio conductio operis faciendi, the Roman contract for the hire of work or services, and bore responsibility for the safe custody and return of the goods entrusted.
Why It Matters in Research
Fullo is not a term of modern law. Researchers encounter it exclusively in Roman law sources, particularly in passages from Justinian's Institutes and the Digest that address the liability of tradespeople who receive goods for processing. The term is significant not for itself but as the paradigm case Roman jurists used to develop rules about the liability of bailees-for-hire. The classical passage — si fullo polienda curandave vestimenta mercede certa constituta acceperit — appears repeatedly in Roman law discussions of custodia liability, the obligation of a hired party to guard against loss or damage to goods in their possession.
Researchers working backward from modern bailment doctrine, from common law innkeeper and carrier liability, or from civilian traditions of professional custodial liability may trace conceptual lineage through these fullo passages. The Digest citations (Dig. 4.9.5; Dig. 19.2.13.6) and the Institutes passage (Inst. 4.1.15) are the primary anchors. Cross-referencing these with discussions of the nauta (shipmaster) and caupo (innkeeper) in the same sources reveals the Roman jurists' broader framework for strict-ish liability imposed on professionals who receive others' property in the course of commercial activity.
Be alert to the fact that secondary sources and legal history treatises may discuss the fullo under the headings of locatio conductio, custodia, or actio locati rather than under the term itself. Searching only for fullo will miss much of the relevant material.
Historical Dictionary Support
Burrill's Law Dictionary gives a compressed but accurate entry: the fullo is a fuller in the civil law, with the definitional anchor being the Institutes passage regarding garments received for smoothing or dressing at a fixed price. Burrill's citations — Inst. 4.1.15, Dig. 4.9.5, and Dig. 19.2.13.6 — are reliable and standard. The entry is functional as a pointer but does not develop the legal significance of the term.
Latin lexicographical sources confirm the ordinary meaning: fullo, fullonis, a cloth-fuller or cloth-dresser, with citations spanning Plautus, Pliny, Martial, and the Digest itself. The legal sources use the term in its plain occupational sense; there is no gap between the Latin word's ordinary meaning and its use in legal texts. The juristic interest lies not in the word but in what the fullo's situation illustrated about Roman liability rules.
Historical legal dictionaries uniformly treat fullo as a civil law term requiring no special legal gloss beyond its occupational meaning. What they do not supply — and what modern researchers need — is the doctrinal context: that the fullo cases were among the key vehicles for Roman jurists working out when and how far a hired tradesperson's liability extended beyond fault to something approaching strict liability for loss of entrusted goods.
Jurisdictional Note
Fullo has no direct counterpart in common law jurisdictions. Its relevance to Anglo-American legal research is historical and comparative: the Roman fullo cases influenced civilian legal systems and, through canon and civil law scholarship, had some indirect effect on the development of common law bailment categories. Researchers in Scots law, South African law, and other mixed jurisdictions may find more direct doctrinal continuity.
