Mirabilia Urbis Serpensiae is a fake treatise about the architecture of the imaginary city of Serpensis. The book is divided in three tomes, where the author inquires the zeitgeist of the three dominating stylistic periods. Professor Mario Garpo is a fictitious academician from the equally fictitious Politecnico di Torcello. He is the world's leading expert on the Mirabilia. On June 30th, 2022, he delivered a lecture on this most curious book within the "Sharing Space"project at Vienna's Angewandte University.
