Two questions. Firstly, Who was Art after whom the Tower at the Unseen University was named? Secondly, Is there any truth in the rumour that the final book in the Moist von Lipwig trilogy will see Moist put in charge of Environmental Issues in Ankh-Morpork, which will include make the river more navigable, is to be called "Passing Water"? or is someone taking the proverbial?
Number one could be a serious question, after all, lots of buildings are named after people. Number two - ah, well, all rumours have to start somewhere, don't they!
