And I came to the land where the sun is a tarnished penny, where the wind is a whip, where two moons play at hot rod games, and a hell of sand gives … - Roger Zelazny

Good-bye and hello, as always.

When I started writing my first novel, ...And Call Me Conrad, they always say: "Write about what you know" and I said "Well, if I get a nice sort of combination SF and Fantasy with these resonances from Greek Mythology it might be pretty good. It would also give me a chance to start filling in my background on all those things I don't know much about but should if I want to be an SF writer."
So I sat down and made a list of everything I felt I should know more about. Astrophysics, oceanography, marine biology, genetics... Then when I'd finished the list I read one book in each of these areas. When I'd finished I went back and read a second book until I'd read ten books in each area. I thought that it wouldn't turn me into a terrific, fantastic expert but I'd at least have enough material there to know if I was saying something wrong. And I'd also know where to turn to get the information I want to make it right.
While I was doing this, to keep the words and cheques flowing I wrote books involving mythology. And once I started picking up things involving astrophysics I'd write stories that played with those sorts of things. So that's why I started out with mythology.

"You were both correct," said Morningstar. "It is the same thing that you both describe, although neither of you sees it as it really is. Each of you colors reality in keeping with your means of controlling it. For if it is uncontrollable, you fear it. Sometimes then, you color it incomprehensible. In your case, a machine; in theirs, a demon."
