Mantica - Vaticanae Lucubrationes - 1645

WHEN SILENCE BECOMES LAW: MANTICA’S GREAT TREATISE ON TACIT AND AMBIGUOUS AGREEMENTS
ABSTRACT
Important treatise of Roman and canonical law on tacit and ambiguous conventions and on the interpretive difficulties of contracts. Francesco Mantica, one of the greatest Italian jurists between the fifteenth and seventeenth centuries and later a cardinal, systematically addresses the cases in which the parties’ will is not expressed clearly.
The work, structured in twenty-seven books, analyzes negotiations, contracts, donations, conditions, obligations, and the interpretation of legal will. This 1645 edition, in two large folio volumes, reissues one of the most authoritative texts of European jurisprudence of the time. A parchment exemplar from the period, with widespread browning and the first volume partially detached from its binding, but complete and of notable historical-legal interest.

WHY TO BUY
MAJOR WORK OF EARLY MODERN LAW – One of Francesco Mantica’s principal works, dedicated to the interpretation of tacit and ambiguous conventions in legal relationships.
27-BOOK LEGAL SYSTEM – The treatise is organized into twenty-seven books and systematically tackles the main forms of bargains and obligations.

MARKET VALUE
The sixteenth- and seventeenth-century editions of Mantica are not rare in absolute terms in major libraries, but complete two-volume folio copies, especially in period bindings, retain steady interest for collectors of ancient law, canon law, and the history of jurisprudence. For the present exemplar, considering the two-volume completeness and the period bindings, a commercial range of about €300–500 is estimated.

Vaticanae lucubrationes de tacitis et ambiguis conventionibus, in libros XXVII dispertitae.
Tomus Primus – Tomus Secundus.
Sumptibus Iacobi Crispini, 1645.
Francesco Mantica.

CONTEXT AND SIGNIFICANCE
The core of the work is the problem of interpreting the will when it has not been expressed clearly. Mantica studies all those situations in which a contract, a donation, a promise, a condition, or a legal disposition presents obscure, incomplete, or implicit formulas. The treatise arose as a natural development of the preceding De coniecturis ultimarum voluntatum, dedicated to the interpretation of testamentary will. In Vaticanae lucubrationes the field is widened to relations between the living and private conventions. Mantica distinguishes general cases from specific fact patterns, bringing together Roman law, canon law, the doctrine of the glossators and commentators, judicial practice, and casuistic interpretation. The work was particularly important because it sought to establish criteria to reconstruct what the parties had actually intended when words were not enough. The theme remains central today in contract law: interpretation of will, good faith, meaning of clauses, and conduct as evidence.

BRIEF BIOGRAPHY OF THE AUTHOR
Francesco Mantica was born in Pordenone in 1534 and died in Rome in 1614. He studied law in Bologna and Padua and taught civil institutions at the University of Padua. He was then summoned to Rome as a judge of the Sacred Rota. In 1596 Clement VIII elevated him to the cardinalate. He was considered, together with Iacopo Menochio, one of the most important Italian jurists of his time, and his works had great authority in the courts. His two main works were De coniecturis ultimarum voluntatum and Vaticanae lucubrationes de tacitis et ambiguis conventionibus. Treccani notes that the Lucubrationes were written during the Roman period and first published in Rome in 1609.

PRINTING HISTORY AND CIRCULATION
The first edition of Vaticanae lucubrationes appeared in Rome in 1609 at the Vatican Press. Google Books lists the first volume with 776 pages. A second Roman edition appeared in 1613 at Curzio Lorenzini; the UNAM catalog describes it in two volumes with [16], 776 pages and [8], 736, [202] pages. Subsequent European editions are documented, including the 1615 Geneva edition at Pierre de La Rovière. The 1645 edition, here present, is labeled on the title page as Editio postrema. Google Books records the two volumes of 1645 separately, with 762 pages for the first and 896 pages digitized for the second. The continuous reprinting of the work throughout the seventeenth century testifies to its long use as a reference text in European legal practice.
