Resumo(s)
A análise cartográfica da rede hidrográfica, no mapa de Portugal de
Fernando Álvaro Seco, mostra por um lado a sua boa qualidade de conjunto e
permite, por outro lado, procurar as causas dos erros de traçado e orientação, bem
como das omissões que se detectam. Confrontou-se, para isso, o traçado dos rios
com descrições de itinerários da mesma época e analisou-se também a repartição
das pontes e da hidronímia. Reconheceu-se uma forte correlação espacial entre a
qualidade da representação e a densidade e frequência dos itinerários viários, e a
influência das preocupações militares relativas à raia oriental do Reino. A correlação com as características do relevo e clima regional é importante, mas menos
directa. O cartógrafo que construiu o mapa procedeu a um complexo trabalho de
compilação e harmonização de documentos de origens diversas, cuja recolha é
provavelmente bem anterior à data da oferta do mapa em Roma, em 1560.
L’analyse cartographique confirme la bonne qualité d’ensemble du réseau et permet de rechercher les causes des erreurs de tracé et d’orientation ainsi que des omissions qui ont été détectées. On a confronté le dessin des cours d’eau avec des descriptions d’itinéraires contemporaines et on a analysé la répartition des ponts et de l’hydronimie. La qualité de la représentation est en forte corrélation spatiale avec la densité et la fréquentation des chemins et paraît liée aussi aux préoccupations militaires relatives à la frontière orientale du royaume. Les liens avec les caractères régionaux du relief et du climat sont importants mais indirects. Le cartographe qui a construit la carte semble avoir réalisé un complexe travail de compilation et d’harmonisation, à partir de documents d’origines diverses, réunis sans doute bien avant la date où cette carte a servi à Rome de présent diplomatique, en 1560.
A cartographic examination of the hydrographic network demonstrates, on one hand, its high quality in general and allows us, on the other hand, to seek reasons for the mistakes in its drawing and orienting, as well as the omissions made. To this effect, the plotting of the rivers was compared with itineraries descriptions of that same period. An examination was also made of the distribution of bridges and hydronymy. A solid spatial correlation was found to exist between the quality of the plotting and the density and frequency of the various itineraries, along with the influence of military concerns for the Eastern boundary of the Portuguese kingdom. The correlation with the regional properties of relief and climate is important but less direct. The map-maker undertook complex work of compilation and harmonisation of documents of several origins, probably dating much further back than to when the map was offered in Rome in 1560.
