Composition: independent from language?

In the light of the terms of the debate outlined in the previous two posts, I want to begin to establish whether composition in painting can have the potential to act independantly from language. I want to apply this to the three paintings posted in the previous weeks. Here I mentioned the possibility of a "compositional syntax". But here the gramatical expresion in this phrase was use metaphorically. And, this is my first criticism of Kress and van Leeuwen in that such terms as "visual literacy", "reading images", or "grammar of visual design" etc all use thst structures in language in a metaphrical way. It is hterefore necessary to investigate these concepts in some depth to see the extent to which their ideas reating to the visual can in fact be seen to function "indepandantly of language".
