What should I ask Toby Wilkinson?

Yes I will be doing a Conversation with him.  He is one of the leading historians of ancient Egypt, and he has a recent book out on Ptolemaic Egypt, namely The Last Dynasty: Ancient Egypt from Alexander the Great to Cleopatra.

Here is his Wikipedia page, he also has served as Vice Chancellor of Fiji National University, and worked extensively as a development director for Cambridge.  Here is his personal home page.

So what should I ask him?
