Mythical Astronomy of Ice and Fire

  • Publisher: Lucifer means Lightbringer
  • Total Episodes: 169

We believe that George R. R. Martin has put a lot of effort and thought into creating a deeper dimension of archetype and symbol in his writing. He’s created connections between past and future, between sky and ground. He’s built on classic figures from world mythology and twisted them around in new and incredible ways to fashion his own archetypal characters whose divine roles are played out by the characters in the story. He’s done all of this not only to be artistic and clever, but because he’s actually participating in a grand tradition of esoteric, symbolic art. Keeping this tradition alive is of critical importance and tremendous value to society, and that is why I believe this facet of A Song of Ice and Fire is so worthy of study. This podcast is intended to be our vehicle to explore these inner workings, and it is fueled by enthusiasm, yours and mine.
