Abstract
El famoso globo terráqueo de
Martin Behaim, concebido y realizado
en Núremberg en 1492, no es el único
testigo medieval de esta forma particular de
representación de la Tierra. Al examinar los
primeros testimonios, nos damos cuenta de
que la función y el contenido de estos globos
cambian significativamente: dejan de ilustrar
los efectos de los fenómenos celestiales y se
limitan a la representación de la superficie de la
Tierra. De ahí las preguntas: ¿cómo y por qué
pasamos de la representación bidimensional
de los mappae mundi a la tridimensional en
el siglo xv? ¿Y cómo y por qué se produjo el
cambio de contenido en las representaciones
tridimensionales? La adaptación de la imagen
ptolemaica a la forma particular de un globo,
y su enriquecimiento con datos de viajes
por tierra en Asia y exploraciones marítimas
en África han surgido antes de Behaim en
círculos germánicos que siguen siendo poco
conocido
Martin Behaim’s famous globe, conceived and realized in Nuremberg in 1492, is not the only medieval witness of this particular form of representation of the Earth. When we examine the first testimonies, we realize that the function and content of these globes change significantly: they stop illustrating the effects of celestial phenomena and are limited to the representation of the Earth’s surface. Hence the questions: how and why did we move from the two-dimensional representation of the mappae mundi to the three-dimensional in the fifteenth century? And how and why did the change of content in the threedimensional representations take place? The adaptation of the Ptolemaic image to the particular shape of a globe, and its enrichment with data from voyages in Asia and maritime explorations in Africa have arisen before Behaim in Germanic circles that are still little known
