Words and pictures, some people claim words are pictures, i suppose they are, but words signify something a little more concrete, a specific idea, moreso than pictures can. A picture is worth a thousand words, so they say, thats probably because pictures are ambiguous, a picture can have more diverse understandings because there's no one right meaning. Whereas words can be defined, cutting off any opportunity for creativity of meaning.
This little book is one of the greatest art pieces ever, the poems which are like childrens stories, like fairytales, are accompanied by beautiful little paintings, and there's no attempt by Blake to make one bow down to the other, it all just fits. Its poetry, some people, like e.e.cummings, would have the words spread out along the page in strange patterns, and the arrangement of words would be important to the understanding. Here, the pictures are actually a part of the poems, and the poems of the pictures. No real distinction is made, and yet it causes absolutely no (visible) anxiety to Blake to break rules and rebuild new ones in such a way.
I guess that's William Blake though, a one of a kind sort of fellow, seems like the kind of person whose asides and throwaway lines would be golden to a lesser artist. And this book is a must.
