Definition
Litera Pisana (also rendered Littera Pisana) is a Latin term meaning "the Pisan letter" — a designation for the distinctive script or character in which the Florentine Pandects, a celebrated manuscript copy of Justinian's Digest, was written. The term refers not to a legal doctrine or rule but to a paleographic feature of one of the most historically significant documents in Western legal history: the manuscript long held at Pisa (and later transferred to Florence), which served as the foundational textual authority for the revival of Roman law in medieval Europe.
The term functions in legal scholarship as a descriptor identifying this specific manuscript tradition and its characteristic hand, distinguishing it from later transcriptions, printed editions, and interpolated versions of the Digest.
Why It Matters in Research
Litera Pisana is not an operative legal term — no rule of law turns on it — but it is essential context for researchers working in Roman law, the history of the civil law tradition, or the transmission of the Corpus Juris Civilis.
The Florentine Pandects (Pandectae Florentinae, also called the Littera Florentina in its later location) represent the oldest extant manuscript of the Digest, and the script in which it was written was itself a matter of scholarly debate and reverence. Medieval glossators and later humanist jurists treated the Pisan text as a benchmark of authenticity. When early modern scholars compared variant readings in the Digest, references to the "Pisan character" or the "Pisan letter" signaled appeal to this high-authority manuscript source.
Researchers encountering Litera Pisana in historical legal treatises or juristic commentary should understand it as an evidentiary marker — an invocation of manuscript authority — rather than a substantive legal term. It appears most frequently in works on Roman law scholarship, textual criticism of the Corpus Juris, and histories of the glossator and commentator schools. It will not appear in common law sources or in any operative legal instrument.
The term is nearly absent from post-medieval practice materials. Its presence in a source is itself a signal: the author is engaged with humanist legal scholarship, civil law textual criticism, or the academic tradition of jurisprudence rather than practical legal argument.
Historical Dictionary Support
Black's Law Dictionary and Burrill's Law Dictionary are in full agreement: both define Litera Pisana as "the Pisan letter," identifying it as the term applied to the old character in which the copy of the Pandects formerly kept at Pisa was written. Both attribute the definition to Spelman — Sir Henry Spelman's glossary of archaic and legal Latin terms — indicating a shared source and consistent transmission through English legal lexicography.
Neither dictionary elaborates beyond this minimal identification, which reflects the term's marginal status in the common law tradition. Its inclusion in English legal dictionaries is a product of completeness and scholarly ambition rather than practical legal necessity. The entry in Black's appears in the context of a cluster of Literae entries covering various Latin instruments and letters, suggesting it was caught in a broad sweep of Latin legal terminology rather than selected for its operational significance.
What the historical dictionaries do not address — and what modern researchers benefit from knowing — is the broader manuscript history. The Pandects were moved from Pisa to Florence in 1406, after which the manuscript is often called the Littera Florentina or Pandectae Florentinae. The earlier designation Litera Pisana thus carries a specific historical period, roughly corresponding to the manuscript's tenure in Pisa and its early influence on the Bolognese glossators.
