MY NAME IS TIRO. For thirty-six years I was the confidential secretary of the Roman statesman Cicero. At first this was exciting, then astonishing, then arduous, and finally extremely dangerous. During those years I believe he spent more hours with me than with any other person, including his own family. I witnessed his private meetings and carried his secret messages. I took down his speeches, his letters, and his literary works, even his poetry-such an outpouring of words that I had to invent what is commonly called shorthand to cope with the flow, a system still used to record the deliberations of the Senate, and for which I was recently awarded a modest pension. This, along with a few legacies and the kindness of friends, is sufficient to keep me in my retirement. I do not require much. The elderly live on air, and I am very old-almost a hundred, or so they tell me.

In the decades after his death, I was often asked, usually in whispers, what Cicero was really like, but always I held my silence. How was I to know who was a government spy and who was not? At any moment I expected to be purged. But since my life is now almost over, and since I have no fear of anything anymore-not even torture, for I would not last an instant at the hands of the carnifex or his assistants-I have decided to offer this work as my answer. I shall base it on my memory, and on the documents entrusted to my care. But because the time left to me inevitably must be short, I propose to write it quickly, using my shorthand system, on a few dozen small rolls of the finest paper-Hieratica, no less-which I have long hoarded for the purpose. I pray forgiveness in advance for all my errors and infelicities of style. I also pray to the gods that I may reach the end before my own end overtakes me. Cicero ’s final words to me were a request to tell the truth about him, and this I shall endeavor to do. If he does not always emerge as a paragon of virtue, well, so be it. Power brings a man many luxuries, but a clean pair of hands is seldom among them.
