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.

For a few thousand years, women had no history. Marriage was our calling, and meekness our virtue. Over the last century, in stuttering succession, we have gained a voice, a vote, a room, a playing field of our own. Decorously or defiantly, we now approach what surely qualifies as the final frontier.

Strangely enough, politics may just be the one realm in which having kids imposes no penalty on women. Kids are practically a necessity. For scientists, or Supreme Court justices, or chief executives, or the woman who wants to learn to fly F-l8s off an aircraft carrier, it works differently.

Motherhood is always an act of courage.

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.

I checked to see if there’d been a really good book published in the last few decades. Then I started with what Cleopatra would have read, asking myself, “What can we know about her education?” It turns out to be a very great deal, and bizarrely, no one had written about that before.
