4.4.3 Prominence of image-G in textual space
Prominence is the comparatively highlighting level of various conceptual parts in a coherent image-G whole and relational prominence shares the closest correspondence with image-G in literary translation.The psychological organization role of relational prominence turns out to be asymmetric，which is a relations of typical figure/ground contrast.Like reversible visual scenes of the face/vase illusion，translators'cognitive processing of distinguishing figure from ground in image-G whole in textual space is also manifested in the scenario construction which is constrained by specific textual context.In different literary discourse or with the changes of situational contexts，the semantic meaning or the prominent meaning of image-G varies.Then the figure/ground assignment of image-G construed by translators is also changed.Any semantic and aesthetic component that can constitute a cognitive reference point will be listed as preferred“ground”and the others that deviate from holistic organization will be put on the position as“figure”of image-G（Kuang &Wen，2003）.The discrepancy in the prominent figure and figure/ground contrast tends to present a covert aspect and is associated with pragmatic practice in literary translation.Take an example from the translation of Cao Zhi's poem“A Groan”（曹植《七哀》）：[11]
明月照高楼，流光正徘徊。
Mingyue zhao gaolou,liuguang zheng paihuai.
Softly on the tower streams of light play;(https://www.daowen.com)
It seems the moon is loath to move away.
(Translated by Xu Yuanchong)
The two lines in ST portray an imagery scene of tranquil moonlight that sleeps upon and casts a gentle light over the tower.In terms of scenario description of image-G,Xu's translation is almost equivalent to ST on account of its correspondence with ST about aesthetic truth value.However,in the frame of prominence dimension,mingyue(bright moon)is the figure,liuguang(streams of moonlight)is the ground and gaolou(tower)is just a part of underlying background in the figure/ground organization of image-G schema in ST.What sets it apart from ST is that gaolou(tower)is highlighted to the position as figure which occupies the focal spot and mingyue(bright moon)is melt invisibly into the background in TT.Thus a completely homogeneous image-G schema in literary translation is not just the copy of the translator's mental picture of prominence organization diagram in ST,nor solely the reflective structuring of translators'conceptual perception about the original's prominence functioning,but rather from recurring interaction of a conceptual-affective reproduction between ST and translators'prominence organism.
