昨天中午下班出门时,门厅里正派发地图,说是测绘局送来的,从世界的到本地的都有。打开一看,原来是“8.29测绘法宣传日”的活动。这类活动很有意思,如果在大街上去散发地图(或许有吧),效果肯定更好。
巧的是,下午amazon就比预计的时间早半天送来一本小书,大概也是为了赶趟——它就是讲一个地图的:The Map that Changed the World, a tale of rocks, ruin and redemption (by Simon Winchester, Penguin Books 2002)。书还没来得及看,从头到脚翻过,就发现有点儿奇怪而且有趣了:书里并没有多少地图,倒是每章题目下面都有一个小化石,像鹦鹉螺一样的,是菊石(Ammonite)。
菊石的样子很像古埃及的公羊神Ammon的角,所以得名ammonite。作者用不同时代的菊石化石来引领历史,是很自然的——特别是地球的历史,因为他讲的那张图是William Smith在1815年绘制的著名地质图。
作者说,地图在诸多方面都是它那时代理想(ambitions)的经典代表,它与其他重大计划一样,也是时代的见证——如OED,如印度大三角测量,如曼哈顿计划,如人类基因。感觉他举这几个例子有点儿不伦不类——但他强调的一点对比我很欣赏:那些大计划“劳民伤财”的(of almost unimaginably vast scope, which required great vision, energy, patience and commitment to complete),而那张伟大的地图却是Smith一个人完成的。Smith的经历,与很多历尽磨难的英雄和天才是一样的:
Smith had little enough going for him: he was of simple yeoman stock, more or less self-taught, stubborn and visionary, highly motivated, single-minded. Although he had to suffer the most horrendous frustrations during the long making of the map, he never once gave up, nor even thought of doing so. And yet very soon after the map was made, he became ruined, completely.
在这个“大科学时代”,顺便重温Smith一个人的故事,也是有意思的。
