A few years ago Infinity Plus did an interview with Jack Dann who is the author of the Clockpunk novel Memory Cathedral. In the interview Jack goes into details about the background about Memory Cathedral and why the novel is not strictly alternative history but can even be thought of as secret history.
So is this alternate history? I think I am probably picking the nits here, but I would think it is secret history, the history that could have been, but we don’t — or can’t know — if it had been. I excerpted a story from The Memory Cathedral, which I reworked and [to which I] added 5,000 words of new material. It was titled “Da Vinci Rising,” and Gardner Dozois bought it for Asimov’s Science Fiction. In that story I have Leonardo’s flying machine affecting Florentine history, changing history. To my mind “Da Vinci Rising” would be alternative history. Something different from the secret history of The Memory Cathedral.
