Greek mythology, and representations of the "figurehead" of the bucentaurs in fact depict the Lion of Saint Mark. The name "bucentaur" seems, indeed, to have been given to any great and sumptuous Venetian vessels. Du Cange quotes from the chronicle of the Doge Andrea Dandolo (): " [... with a well-wrought and stately Bucentaur, upon which he came to San Clemente, where a more important and more stately Bucentaur had already arrived with his advisors, etc. ...]". The term was also used to describe a 16th-century sumptuous transport boat, built and decorated in Modena, to celebrate the marriage of Lucrezia, the daughter of Ercole II d'Este, Duke of Ferrara, to the Duke of Urbino. The vessels Before the age of the bucentaurs, it is probable that for ceremonies in the Venetian Lagoon the doge was simply assigned a small galley from the Venetian fleet. As Venice's wealth increased due to its naval power, plans were made for a special ship to be built. This is evidenced by the promissioni – sacramental pledges spoken by the doges when they were sworn into office – of Reniero Zeno of 1252, Lorenzo Tiepolo of 1268 and Giovanni Soranzo of 1312 which mention the construction of a bucentaur in the Arsenale shipyard and naval depot. The 1311 bucentaur Historians agree that four major barges were built. While there are believed to have been earlier vessels, the bucentaur of 1311 is regarded as the first significant one, for on 17 August 1311 the promissione was amended to add the statement "quod Bucentaurus Domini ducis fiat per Dominium et teneatur in Arsenatu" ("... that a Bucentaur should be made for the Lord Doge for his rule, and it should be held in the Arsenale"). This was the first time that Venetian law had provided that the expense of building the bucentaur was to be borne by the public budget. The two-decked bucentaur had a tiemo (canopy) with two sections, one in purple velvet for the doge, the other in red velvet for Venetian nobles. The historian Marino Sanuto the Younger, in his work De origine, situ et magistratibus urbis Venetae (On the Origin, Site and Officials of the City of Venice), also described the ship as bearing a sculpture of Justice. The bucentaur was used not only for the Marriage of the Sea ceremony, but also for other state functions such as festivals celebrating the Virgin
