Works
I own and have read Begegnung in Bolzano, the German translation of Marai's book. I thought it pretty good and now I discover it is a modern masterpiece only just translated into English. I don't think the name Casanova is ever mentioned in the book: but we know who he is.
But the Casanova of the book seems a bit more wise and in control than the one of history. A bit more important. But perhaps just as the hero of his own life.
