Ordinamenta et consuetudo maris
The Ordinamenta et consuetudo maris ("Ordinances and Custom of the Sea") was a convention governing maritime trade promulgated at Trani in 1063: "the oldest surviving maritime law code of the Latin West". The Ordinamenta is preserved in a Venetian version appended to a copy of the Statuta Firmanorum, the statutes of the commune of Fermo, printed in a single volume at Venice "under the auspices and care, through the diligence, and at the expense of Marcus Marcellus, a citizen of Venice, and a native of Petriolo, a small village in the circle of Fermo, at the press of Nicholaus de Brentis and Alexander de Badanis, the Lord Leonardo Loredano being Doge, A.D. MDVII" (1507).
