Overview: The Galea da Mercato, or Galea Grossa ("great galley"), was Venice's state-built merchant galley, a hybrid oar-and-sail vessel that combined warship-like construction with cargo capacity. Venice developed this type from the earlier galea sottile, giving it a greater beam and reduced hydrodynamic performance in exchange for enhanced cargo capacity, making it a compromise between military and commercial needs suited to trading high-value cargoes with the East. Specifications: Length was about 50 metres and beam about 7 metres, with provision for 25 banks of rowers. By the 15th century these ships typically carried multiple lateen-rigged masts in addition to their oars, and were armed with crossbows and increasingly shipboard guns for self-defense; the heavier hull form traded speed for hold space and stability compared to the lighter galea sottile war galley. Service History: Control of the galleys passed into public ownership, with private citizens limited to chartering freightage aboard vessels that undertook the state-organized muda trade convoys. These convoys, made up of galea grossa da merchado and led by a Captain appointed by the Venetian Senate, were named for the regions they served (Muda of Syria, Muda of Egypt, etc.) and ran on a fixed seasonal schedule. The type carried Venice's most valuable trade goods for roughly three centuries before declining profitability led to its gradual abandonment by the 16th century. Notable Facts: Later Venetian galleasses were based on existing models of these great galleys used to carry heavy loads for trade. No hull of this class survives; knowledge of the type comes largely through contemporary art and manuscripts, including Venetian harbor paintings by Vittore Carpaccio and the illustrated 1486/87 pilgrimage account of German traveler Konrad von Grünenberg, who traveled to the Holy Land aboard a Venetian great galley owned by patron Agostino Contarini and illustrated the vessel in his manuscript.
