Notes
I would like to thank, first and foremost, Steven A. Epstein, Enrico Basso, Giustina Olgiati, and the three anonymous readers for their helpful comments on this paper. Alfonso Assini, Michel Balard, Laura Balletto, Franco Cardini, Marina Montesano and Antony Molho read the manuscript and offered many useful suggestions. I would also like to thank Lorena Barale and Valentina Ruzzin for their meticulous proofreading. Alessandro Angelucci and Costanza Tognini helped me with the English text.
