矗立在埃及沙漠中吉萨的三座大金字塔建于4000年前,它们一直都是有史以来最宏大的建筑.
金字塔是埃及人在他们的领袖——名为法老——的命令下建造的.在公元前2615年左右,几任法老相继统治埃及,基奥普斯法老建造了有史以来最大的金字塔——大金字塔,也被称为胡夫金字塔.胡夫金字塔每边长770英尺,高481英尺.古代的建筑者是如何建造这些庞然大物的,这一直是个未解之谜,但很明显它需要付出大量的脑力和体力.
有工程天才的参与吗?是的,有.比如,当你要把一个石块放在顶端时,你该如何把一个几吨重的石块提升到480英尺的高度呢?应该怎样做?怎么做才不至于在塔身留下刮痕?把几吨重的石块提举到480英尺的高处又需要多少人力呢?为了建造大金字塔,人们切割、运输、垒砌了大约230万块石头.
法老们的初衷是为自己建造豪华的陵墓,而最终他们创建的却是昭示人类潜能的纪念碑.金字塔蕴含着一种共同的信息,金字塔属于埃及,但它也属于世界.因此我们完全可以把金字塔作为展示人类伟大文明的早期纪念物.
由于历经岁月的沧桑,金字塔位列十大人工奇观排行榜第2名.
