I did not know Shona well, but enjoyed the few occasions when I did meet her, including the memorable session at the Renaissance Society of America conference in Venice, where the venue (the vast and magnificent refectory of San Giorgio) did justice to the papers even if the audience didn't! Today I was reading about the 1321 exodus of students from Bologna and found myself needing to check some details, turning automatically to her book. I have been thinking about her and her family ever since I heard the news on the day after she died, but it still brought me up short to realise that this would not be followed by other work from the same pen. It will remain as a testament (no pun intended) to her clarity of thought and mastery of the history of Bologna and its university but how I wish there could have been more, and that she too could have enjoyed the long years of the testators whose lives she studied.
