Traça a transição do instrumental astronómico de tradição islâmica e ocidental para o instrumental náutico que acompanhou a expansão marítima portuguesa e ibérica, com apoio de ilustrações e fac-símiles. Contributo de referência para a história da náutica e da ciência dos Descobrimentos. ¶ [EN] This study, written in English and presented at the 1st International Meeting on the History of Navigation (1968), examines the medieval origins of scientific instruments and their evolution into the navigational instruments used in the 15th and 16th centuries, particularly the astrolabe and related instruments. It traces the transition from astronomical instruments of Islamic and Western tradition to the nautical instruments that accompanied the Portuguese and Iberian maritime expansion, supported by illustrations and facsimiles. It is a key contribution to the history of navigation and the science of the Discoveries. ¶ ⚑ Auto-translated via Google Translate.…
