Definition
A boatman; a coxswain. In historical legal usage, cocksetus referred to a person who operated or steered a small boat or vessel — the individual in charge of a ship's cockboat or similar watercraft. The term appears in medieval and early modern legal texts, particularly in contexts touching on maritime duties, ferry rights, and obligations associated with river or coastal passage.
Why It Matters in Research
Researchers are unlikely to encounter cocksetus in any modern legal instrument, statute, or judicial opinion. Its relevance is confined almost entirely to historical legal documents — particularly medieval English records, manorial rolls, and texts dealing with riparian or maritime obligations. When the term surfaces in such documents, it typically identifies a person by occupation rather than defining a legal right or duty in itself. The occupational designation may carry significance in establishing who bore liability for safe passage, who was entitled to certain tolls or ferry rights, or who owed service obligations under a tenure arrangement.
The term is Latin in form and belongs to the class of occupational descriptors common in medieval legal Latin, where a person's trade or role was used to fix their legal status or duties within a given instrument. Researchers working with early English court records, pipe rolls, or documents related to waterway rights and ferry monopolies should be alert to variant spellings. Cowell's Interpreter, cited by both Black's editions, is the primary secondary source connecting this term to English legal usage.
Historical Dictionary Support
Both editions of Black's Law Dictionary agree entirely on the substance: cocksetus means a boatman or cockswain, and both cite Cowell as the authority. John Cowell's Interpreter (1607) is the underlying source, and the definition has passed forward without modification or expansion across the two editions. Neither edition situates the term within a broader legal doctrine or provides illustrative context beyond the bare occupational meaning. No divergence exists between the two sources, and neither attempts to extend the term beyond its descriptive function. Researchers should note that Cowell's Interpreter itself is a historical legal dictionary of early modern English law, meaning cocksetus was already an antiquarian entry by the time Cowell wrote — further evidence that the term's active legal life predates the common law period most researchers work within.
