Like many of you, I've been playing D&D since 1980 (in other words A LONG TIME). The term "Vancian Magic" is thrown around a lot and it wasn't until I read "Tales from the Dying Earth" that I knew what it meant.
In my younger years, I was a big reader of Moorcock and Leiber. I read "The Hobbit" but I struggled with LOTR. I read Robert Asprin, Larry Niven and Ray Bradbury.
I didn't read Vance until much, much later.
I'm so glad that I did.
I believe that I read somewhere that the word "libram" is a Vancian invention. He does have a way with words and phrases. His spell names are fantastic!
Ioun stones are his. Prismatic Spray is his. What else in our favorite game has it's origin in his stories?
If you haven't read "The Dragon Masters" you really should.
One tidbit that I learned only recently was that "Ellery Queen" was, in fact, Jack Vance.
My Dad loved Ellery Queen. I love Jack Vance. I guess that's one more thing that I had in common with my old man. :)
