In 'Plutarch,' her voice begins to come out; there are actual 2,000-year-old quotes from Cleopatra, and they are sly and saucy.
From every ancient source, we have testimony to Cleopatra's irresistible charm, as Plutarch has it, to her ability to speak many languages including, as he puts it, the language of flattery and essentially, to be able to turn people to her will - really a great political genius, in that respect.
I once interviewed David Herbert Donald, the Lincoln historian, and we talked about how one deals with the secondary sources and the previous biographies. He said something which kept coming back to me as I worked on Cleopatra, which was: 'There's no further new material; there are only new questions.'
Cleopatra had one great advantage. She lived at a time when female sovereigns were not anomalies. And when women enjoyed rights they would not again enjoy for another 2,000 years. You could call them early feminists, if I may use a dirty word.
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.
Life-writing calls for any number of dubious gifts: A touch of O.C.D., a lack of imagination, a large desk, neutrality of Swiss proportions, tactlessness, a high tolerance for archival dust. Most of all it calls for an act of displacement. 'To find your subject, you must in some sense lose yourself along the way,' is Richard Holmes's version.
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.
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.
In an ideal world, the perfect biographical subject would have been the star of his penmanship class at grade school - and would thereafter write an English that positively sings.
I don't think there is ever objective biography. Our vision of our subject is always shaped by who we are. So I do, of course, think the biographer's view is always something to keep in mind.
You have to scuba dive in the Alexandrian harbor if you want to see what remains of the lighthouse of Cleopatra's day, and the water in the Alexandrian harbor is not really something you want to come into contact with.
The interesting thing about Cleopatra is that she is such a shape-shifter. I mean through history we've all molded her to our times and our places. So there's room for a movie for her, but I don't think it will hew to the book.
