22、遗址距今的年代为指标。半坡遗址的年代,距今有6 000年左右。我认为,这也就是汉字发展的历史。 半坡遗址是新石器时代仰韶文化的典型,以红质黑纹的彩陶为其特征。其后的龙山文化,则以薄质坚硬的黑陶为其特征。值得注意的是:半坡彩陶上每每有一些类似文字的简单刻画,和器物上的花纹判然不同。黑陶上也有这种刻画,但为数不多。刻画的意义至今虽尚未阐明,但无疑是具有文字性质的符号,如花押或者族徽之类。我国后来的器物上,无论是陶器、铜器或者其他成品,有“物勒工名”的传统,特别是殷代的青铜上有一些表示族徽的刻画文字,和这些符号极为相类似。由后以例前,也就如由黄河下游以溯源于星宿海,彩陶上的那些刻画符号,可以肯定地说
23、就是我国文字的起源,或者是我国原始文字的孑遗。 同样值得注意的是彩陶上的花纹。结构虽然简单,而笔触颇为精巧,具有引人的魅力。其中有些绘画,如人形、人面形、人看长衫形、鱼形、兽形、鸟形、草木形、轮形(或以为太阳)等等,画得颇为得心应手,看来显然在使用柔软形的笔了。有人以为这些绘画是当时的象形文字,其说不可靠。当时是应该有象形文字的,但这些图形,就其部位而言,确是花纹,而不是文字。 在陶器上既有类似文字的刻画,又有使用颜料和柔软形的笔所绘画的花纹,不可能否认在别的质地上,如竹木之类,已经在用笔来书写初步的文字:只是这种质地是容易毁灭的,在今天很难有实物保留下来。如果在某种情况之下,幸运的还有万一的
