文学人类学提出的具有交叉学科意义的新方法论为四重证据法,各重证据之间具有互阐作用。其中作为图像叙事的第四重证据内部的不同材料间的互补互证效应,理论上总结为"证据间性"问题。以2001年西安窦氏墓出土玉组佩为典型案例,以玉组佩顶端的熊纹猴纹透雕玉璧为解读突破口,发挥先秦两汉时代大量积累的各种图像材料的系统化求证作用,包括铜牌饰、建筑装饰、玉器、画像石等,可以重建失落的上古时代天国神话想象景观,辨析围绕升天主题的运载神物(龙、凤)、升天目标"天门"及其玉璧象征,以及驾驭运载神物的神灵主体的动物化身形象"天熊"。通过有效利用证据间性可实现上古图像整体解读的案例,揭示四重证据法的知识创新意义及拓展前景。
The quadruple-evidence approach is a new interdisciplinary method introduced by literary anthropology,in which all evidences are mutually interpretative. Different materials in image narration as the fourth evidence of the four are mutually supplementary and mutually evident in effect,which is theoretically generalized as the evidence interrelation. Taking the serial jade pedants unearthed from the Dou Family Tombs in the West Han Dynasty as the case,and the bear-line and monkey-line deep-carved jade at the top end of the serial jade pedants as the interpreting point,we can reconstruct the imaginary picture of the lost heavenly mythology in the pre-historic days by giving a display of systematic confirming function to varieties of graphic materials gathered in the pre-Qin and West and East Han times. Careful discriminative analysis should be done about the mythic creatures in the heaven-ascending mythology(dragon and phoenix),the "heaven-gate"as the heaven-ascending aim and its jadecarved symbol,and the"heavenly-bear"the deity subject to control the mythic carriers. In this way a complete interpretation of the case of the pre-historic image can be done by effectively applying the evidence interrelation so as to reveal the innovative significance and extensive prospect of the quadruple-evidence approach.
