Definition
An archaic Latin legal term denoting a watch or guard — specifically, the organized keeping of watch as a civic or military duty in medieval law. The term appears in old Latin legal texts and glossaries to describe the institution or act of maintaining a nighttime or sentinel watch, typically as a communal obligation owed by inhabitants of a town or manor.

Why It Matters in Research
Bigla is a term a researcher is unlikely to encounter outside of medieval Latin legal texts, glossaries, and antiquarian dictionaries. Its primary significance is as a term of art in sources dealing with feudal obligations, borough customs, and municipal duties in early English and continental European law.
Researchers working in medieval legal history should be aware of several traps:
First, the term does not appear in standard modern legal dictionaries and is absent from most 19th-century American legal reference works. Its presence in Burrill signals that it circulated in the Anglo-American antiquarian legal tradition primarily through learned citation back to continental scholars such as Meursius and Spelman, rather than through active use in English courts or statutes.
Second, bigla belongs to a cluster of related feudal service terms — watch, ward, and castle-guard — that appear frequently in early English land tenure documents. A researcher encountering bigla in a Latin text should immediately consider whether the document is describing a tenure obligation, a borough custom, or a military duty, as the context will determine which parallel body of law applies.
Third, the term's Greco-barbarous origin (from the Greek βιγλα, itself derived from Latin vigilia, meaning a watch or vigil) means it may appear in variant spellings or transliterations across different manuscript traditions. Cross-referencing against Spelman's Glossarium and Du Cange's Glossarium Mediae et Infimae Latinitatis is advisable when the term appears in primary sources.

Historical Dictionary Support
Burrill's Law Dictionary is the sole shelf source for this entry and provides a compact but reliable treatment. Burrill traces the term through two authorities: Meursius (Johannes Meursius, the Dutch classical scholar whose lexicographical work on medieval Latin was widely cited) and Spelman (Sir Henry Spelman, whose Glossarium Archaeologicum remains the foundational reference for Anglo-Latin legal and feudal terminology).
Burrill correctly identifies the Greco-barbarous pathway: the Latin vigilia (watch, vigil) passed into Byzantine Greek as βιγλα, and from there back into medieval Latin legal usage as bigla. This linguistic path is characteristic of terms that entered Anglo-Norman and early English law through channels influenced by Byzantine and continental European administrative practice.
No other shelf source in the standard Law Mind corpus treats this term directly. Researchers should not expect to find bigla in Bouvier, Black, or Tomlin — its survival in English legal reference literature depends almost entirely on the antiquarian tradition running through Spelman and those who cited him.

Jurisdictional Note
Bigla, as an operative legal term, belongs to medieval law rather than to any modern jurisdiction. It has no active doctrinal content in current English, American, or comparative law. Its relevance is confined to historical legal research, particularly work touching on feudal tenure, borough obligations, and Latin manuscript sources from the medieval period.
