Abstract

The shape of Africa on Iberian nautical charts of the late-fifteenth and early-sixteenth century is surprisingly mature. The portrayal of the outline of Africa on the Cantino planisphere of 1502 is so good that it was not surpassed in the next two, possibly three centuries. The African coastline on the Cantino planisphere is a mosaic of accurate regional charts on the plate-carrée projection, each with its own scale and orientation. The same holds for its Iberian predecessors. The shape of the parts of Africa depicted on these regional charts was essentially correct on the oldest chart (c. 1471) and was copied to later charts. The projective properties of the regional charts are incompatible with the navigation and charting techniques used in that period. Therefore, serious doubt is cast on the established view that Portuguese pilots and cartographers were the original creators of the source charts.
发现时代航海图上的非洲地图
在15世纪末和16世纪初的伊比利亚海图上,非洲的形状出奇地成熟。1502年Cantino planissphere对非洲轮廓的描绘是如此之好,以至于在接下来的两个,甚至三个世纪里都没有人超越它。Cantino平面球上的非洲海岸线是由精确的区域图表拼接而成的,每个图表都有自己的比例和方向。它的前身伊比利亚也是如此。这些区域海图上描绘的非洲部分地区的形状在最古老的海图(约1471年)上基本上是正确的,并被复制到后来的海图上。区域海图的投影特性与当时使用的导航和制图技术不相容。因此,葡萄牙航海家和制图师是原始海图的原始创造者这一既定观点受到了严重的质疑。
