Resumo(s)
Este trabalho centra-se na figura de Francisco Faleiro e na sua obra enquanto cosmógrafo. Em primeiro lugar, apresenta-se o contexto cosmográfico em que Francisco Faleiro esteve inserido: Sevilha no início do séc. XVI. Segue-se a reconstituição da sua biografia, a partir dos dados dispersos e de alguns documentos disponíveis. Analisa-se, de seguida, a mais importante obra de Faleiro, o Tratado del Esphera y del arte del marear, publicado em 1535. A partir da obra de Faleiro é possível perceber quais os seus maiores contributos para os problemas da náutica do seu tempo, em particular a declinação magnética. Analisa-se ainda um parecer que foi pedido a Faleiro, sobre as cartas de dupla latitude de Diego Gutiérrez, e uma polémica acerca da prioridade do instrumento de sombras apresentado por Faleiro no seu Tratado. Faleiro foi um cosmógrafo talentoso e reconhecido no seu tempo. Foi pioneiro em diversos aspectos e o seu contributo para a náutica e cosmografia foi de extrema importância. O que se pretende destacar com este trabalho, no entanto, é o papel central da obra de Faleiro na génese e definição de uma nova tradição cosmográfica, o novo género literário dedicado a assuntos náuticos (tratadística náutica, manuais de cosmografia, artes de marear) que surgiu no início do séc. XVI.
This dissertation focuses on the figure of Francisco Faleiro and his work as a cosmographer. We first present the cosmographic context in which Francisco Faleiro was inserted: Seville at the beginning of the 16th century. This is followed by the reconstruction of his biography, based on scattered data and some available documents. Next, we will analyze Faleiro's most important work, the Tratado del Esphera y del arte del marear, published in 1535. From Faleiro's work it is possible to understand his major contributions to the nautical problems of his time, in particular the issue of magnetic declination. We also analyze a response to a technical question (parecer) that was asked of Faleiro, about the double latitude charts of Diego Gutiérrez, and a controversy about the priority of the instrument presented by Faleiro in his Tratado. Faleiro was a talented and recognized cosmographer in his time. He was a pioneer in several aspects and his contribution to nautical science and cosmography was extremely important. What we want to highlight with this work, however, is the central role of Faleiro's work in the genesis and definition of a new cosmographic tradition, the new literary genre dedicated to nautical subjects (nautical treatises, manuals of cosmography, artes de marear) that emerged in the early 16th century.
