When will you be rereleasing the video series Transformations of Myth Through Time?

We won’t.

The Mythos DVD series contains all of the footage in Transformations plus 2+ hours of never-before-released lectures, and presents them as Campbell intended:

• Mythos I: The Shaping of Our Mythic Tradition (DVD)
  an exploration of the psychology, history and biology of myth, and an introduction to the Western mythos.
• Mythos II: The Shaping of the Eastern Tradition (DVD)
  an introduction to the great mythic traditions of South and East Asia.
• Mythos III: The Shaping of the Western Tradition (DVD)
  an exploration of the great philosophy, art and literature that have shaped the modern West.
