本课简介
今天,地图上上为北标示在我们的眼里极其自然。很难想像出会有一幅不以上为北的地图。但是当我们试图去了解地图绘制的历史时,我们会有超乎想像的发现。
世界上古老的地图绘于公元前3800年。几个世纪以后,是古希腊人开始用相对科学的方式来绘制地图,其最杰出的先驱是托勒密。古巴比伦人以扁平的圆盘状来展现地球,而托勒密则以球状来展现地球。鉴于当时人们的知识的状态,托勒密在绘制地图时也出了种种差错,但是他是标示地图的上方为北方的第一人。
到了中世纪,欧洲教会严重阻碍了科学的发展。因为耶路撒冷是基督教的圣地,于是地图的上方便改换为东方。直到十四世纪,由于贸易的发展,以及人们对指南针的日益加剧的依赖,北方终又成为地图的上方。
