The mutual imitation of language art and image art has drawn much attention in the literary history at home and abroad. However

there is an asymmetry in terms of the mutual imitation: image imitating language is referred to as the clockwise imitation

while language imitating image the anticlockwise imitation. Lessing has realized this point in Laocoon and made a new discovery after incorporating it into the context of "the age of literature's encountering image"that the primary reason for the asymmetry of mutual imitation lies in the different symbol attributes. Language is symbol of congruent reference

which is dominant

while image is symbol of phantom reference

which is weak. Therefore

deconstruction and expulsion

or delay and oblivion of image on the part of language are likely to occur when the two symbols share a text. Such being the case

language itself will not be harmed in the situation of literature visualization

while image

as a carrier and tool

helps spread literature.
