Definition
A church calendar or rubric. The term appears in early English ecclesiastical usage to describe the formal ordering of the church year — a calendar designating feast days, fasts, saints' days, and the liturgical cycle. As a rubric, it refers to the directive or heading within a religious text governing the order of services or ceremonial observance.
Mertlage is a term of narrow historical and ecclesiastical significance. It carries no active legal meaning in modern practice.

Why It Matters in Research
Researchers are unlikely to encounter mertlage as a substantive legal term. Its appearance in Black's Law Dictionary reflects the older lexicographic practice of including ecclesiastical and antiquarian terms drawn from sources like Cowell's Interpreter (1607), which compiled Latin, Law French, and early English legal and quasi-legal vocabulary regardless of whether a term had active judicial application.
The practical research implication: when mertlage appears in a historical legal document, it is almost certainly functioning in an ecclesiastical or administrative church context rather than a secular legal one. Its relevance would typically be in disputes touching on church property, benefices, tithes, or the duties of clergy — areas where civil and canon law intersected in English legal history.
Both editions of Black's cite Cowell as the sole authority, which signals that the compilers themselves were relying on a secondary antiquarian source rather than case law or statute. Researchers who trace the term through Black's are therefore at two removes from any primary source: Black's cites Cowell, and Cowell was himself synthesizing older ecclesiastical usage.
Note the placement in both editions: the mertlage entry is immediately followed by the entry for the Statute of Merton (1235). This adjacency is purely alphabetical and carries no substantive connection. Researchers should not infer a relationship between the two terms.

Historical Dictionary Support
Both the first and second editions of Black's Law Dictionary give an identical one-line definition — "a church calendar or rubric" — with attribution to Cowell. Neither edition elaborates further or provides illustrative context. The second edition adds slightly more surrounding text for the neighboring Statute of Merton entry but does not expand on mertlage itself.
The brevity of the entry across both editions is itself informative: the term was recorded as a matter of completeness rather than practical utility. No divergence between the two editions exists on this term.
Cowell's Interpreter, the cited source, was a comprehensive glossary of legal and quasi-legal terms in use at the time of its composition in the early seventeenth century. It drew on civil law, canon law, and common law vocabulary indiscriminately, which explains how an ecclesiastical term like mertlage came to be preserved in legal dictionaries at all. Researchers consulting Cowell directly should be aware that his definitions occasionally reflect contested or archaic usage, and that the Interpreter was itself suppressed shortly after publication for political reasons before being revised and republished.
No other standard historical legal dictionary in the Law Mind corpus — neither Bouvier nor Tomlin nor Jacob — appears to carry an independent entry for mertlage, which further confirms its peripheral status in the legal lexicon.
