More un-London, monsoon-like rain.
I am an enemy of symbols. Symbol is too narrow a concept for me in the sense that symbols exist in order to be deciphered. An artistic image on the other hand is not to be deciphered, it is an equivalent of the world around us. Rain in Solaris is not a symbol, it is only rain which at certain moment has particular significance to the hero. But it does not symbolise anything. It only expresses. This rain is an artistic image. Symbol for me is something too complicated.
