Title: Santo Antonio de Tanna story and reconstruction
Author: Fraga, Tiago Miguel
Abstract: Buy a puzzle , assemble it , and destroy its original box . Take the puzzle , go to a lake , throw the puzzle in the lake , and leave it for a few weeks . Return to the lake and try to rebuild the puzzle from the remaining pieces . Such is the challenge of the research goals presented on this abstract ? the reconstruction of a Portuguese frigate , Santo Antonio de Tann ? , from its submerged remains . This thesis focuses on the mechanisms of reconstructing the ship , including the thought process , new computer tools , and imagination required for an archaeologist to be a detective of lost eras . The main objective was to understand the construction of a late Seventeenth -century Portuguese frigate . Frigates were responsible for patrolling the seas , intercepting fastmoving vessels , re -supplying military trading stations , and protecting trade routes . The existence of Portuguese frigates was known from historical records , but Santo Antonio de Tann ? is the only frigate identified in the archaeological record . As such , its reconstruction should enable scholars to better understand the actual capabilities of seventeenth century frigates .A particular challenge in this study was ascertaining the manner in which Santo Antonio de Tann ? ?s construction reflected the state of affairs of the Portuguese trade network . Although their construction methods were advanced , the Portuguese adopted a shipbuilding design that was not able to compete as well in the new conditions of a changing global context . This study clearly demonstrate that cargo capacity was given greater emphasis than either speed or maneuverability , illustrating the on -going necessity of the Portuguese to build military ships with cargo capacity sufficient for minimal trade , even at the expense of speed . These were just the first steps in terms of what could be learned from the reconstruction . The best method to understand the ship , a three -dimensional object , was to recreate it into a three -dimensional environment in order to create a more accurate model . The resulting model permitted research to extend beyond the limits of the individual line drawings through the added benefit of being able to calculate hydrodynamics , sailing characteristics , and other data based on the ship ?s morphology .
