Book excerpt: Francesco Colonna's weird, erotic, allegorical antiquarian tale, "Hypnerotomachia Poliphili", together with all of its 174 original woodcut illustrations, has been called the first "stream of consciousness" novel and was one of the most important documents of Renaissance imagination and fantasy. The author -- presumed to be a friar of dubious reputation -- was obsessed by architecture, landscape and costume (it is not going too far to say sexually obsessed) and its woodcuts are a primary source for Renaissance ideas.
