Cleopatra stood at one of the most dangerous intersections in history that of women and power. Clever women, Euripides had warned hundreds of years earlier, were dangerous.

I'm a sucker for lost worlds. I was nostalgic even as a child. I was happiest in my hometown library in Adams, Mass., where nothing seemed to change.

And in the absence of facts, myth rushes in, the kudzu of history.

We don't know how Cleopatra spent her days, but we do know how other Hellenistic monarchs spent their days. There has been a great amount of scholarship in the last 30 years about education in the Hellenistic world and women in the Hellenistic world. We now know how an upper-class woman was educated in her day.

No one in the modern world controls the wealth or territory that Cleopatra did.

Power has for so long been a male construct that it distorted the shape of the first women who tried it on, only to find themselves in a sort of straitjacket.

An interesting thing about book groups, it seems to me, is that there is no correlation between a brilliant book and a brilliant discussion. The first seems sometimes even to undermine the second.

No one sits on the stoop when she's a kid and thinks, 'I want to be a biographer when I grow up,'

Here you have an incredibly ambitious, accomplished woman who comes up against some of the same problems that women in power come up against today. Cleopatra plays an oddly pivotal role in world history as well in her lifetime, Alexandria is the center of the universe, Rome is still a backwater.

Ancient history is oddly short on incorrect omens.

Women enjoyed rights in Egypt they would not again enjoy for more than 2,000 years. They owned ships, ran vineyards, filed lawsuits, practiced medicine. Their husbands supported them after divorce. Their power was unprecedented.

It has always been preferable to attribute a woman's success to her beauty rather than to her brains, to reduce her to the sum of her sex life.
