Gabriel Byrne

I would love to go back to any time in European history, especially in Irish history, to the second or third century, prior to the arrival of Christianity when Paganism flourished. I can always go back there in my imagination, of course. It doesn't cost anything, and it's a form of time travel, I suppose.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
