Decifrando mapas:sobre o conceito de "território" e suas vinculações com a cartografia

This essay studies the cartographic documentation left by military engineers in Portugal, during the 18th Century. The technical dimension of map making is analysed, focusing on the instruments and the methods employed both in field surveys and in subsequent graphic representations. From the point of view of Material Culture, maps are understood as cultural artefacts, therefore historical artefacts; in this sense, the particularities of cartographic language reveal the world conceptions particular to each period. This article proposes a methodology of morphological analysis of the cartographic language, deconstructing the several strata in the organisation of this kind of visual representation. In order to do so, a vast array of heterogeneous correlate documents is mobilised, such as practical geometry, drawing and architecture treatises, contemporary to the period studied.O ensaio versa sobre a documentação cartográfica legada pelos engenheiros militares, em Portugal, no século XVIII. Analisa a dimensão técnica da produção de mapas, focalizando os instrumentos e os métodos empregados nos levantamentos de campo e no desenho de gabinete. Do ponto de vista da cultura material, os mapas são interpretados como artefatos culturais e, portanto, históricos; dessa forma, as particularidades da linguagem cartográfica revelam as concepções de mundo, o estado do conhecimento científico, as convenções e os códigos de representação próprios de cada período. Propõe uma metodologia de análise morfológica da linguagem cartográfica, desconstruindo os diversos estratos da tessitura desse tipo de representação visual. Para tanto, mobiliza um vasto campo de documentos correlatos, heterogêneos, tais como tratados de geometria prática, desenho e arquitetura, contemporâneos ao objeto de estudo

Todas as criaturas do mundo: a arte dos mapas como elemento de orientação geográfica

Vague in the outlines and abounding in figures of real or fabulous creatures, the iconography of medieval maps played a significant role in helping users to recognize lands that were virtually unknown to Christendom. In a world with no reliable latitudes and longitudes, the land contours, inhabitants and even certain elements of fauna and flora could become variables of utmost importance for geographic orientation. Notwithstanding the higher levels of precision achieved in their efforts to represent geographic space, the considerable advancements made in latitude determination, and their continuous pursuit of a practical method for the establishment of longitudes, the cartographers of the Age of Discoveries still went to the trouble of depicting notable elements - whether real or imaginary - to help travelers get their bearings around different regions of the globe. As the presence of Europeans continued to expand and an authentic scientific revolution took place in the 17th century, the lengthy notes and eye¿catching representations of nature and local inhabitants soon lost their utility as points of reference on 17th-century maps to become mere accessories of aesthetic and commercial value. The advent of the 18th century consolidated, once and for all, the transformation of such illustrations into essentially decorative elements with no other relevant role to play in mapmaking. In addition to decreasing in number, the figures became more stylized and moved to the borders of the maps as ornamental motifs. Although they often maintained some sort of relation with the geographic space depicted on the map, the motifs chosen could also constitute a rather independent element. In fact, allegories, compositions with a variety of mythological figures, and historical representations were often used to underscore the power of certain political agents
