The Mystery of Hamlet, King of Denmark, or What We Will, a Tetralogy by Percy Mackaye, (HC, 1950, 676 pages, $5, which is 1/3 the internet price.)
Sometimes I write about things I think are just plain weird. This is one of them. Percy Mackaye wrote a "Prologue" to Shakespeare's play Hamlet. Actually, this "prologue" is in the form of 4 plays:
The Ghost of Elsinore
The Fool in Eden Garden
Odin Against Christus
The Serpent in the Orchard
Feel free to check out this book, which "was experienced rather than 'written', and is concerned chiefly with realities of experience. The writing of it was incidental to the revealing of it. For it was not planned beforehand by me. It was compelled- with exacting, disciplinary gentleness- by powers within and beyond this material scene...
I still don't get it. Look for this book shelved next to the Hamlet books, for lack of a better place to put it.
