Since then I've done a little research on Hinton, Donchian, et al., and have found a number of other links between the idea of a fourth spacial dimension and various forms of spirituality or mysticism. For instance, the German astronomer Friedrich Zöllner (1834 – 1882) apparently tried to use the fourth dimension explain Spiritualist phenomena. In his eagerness, he was imposed upon by the medium Henry Slade in experiments that have since been debunked. Fantasy and horror authors in their turn used the claims of Spiritualism in their stories; some, like Arthur Machen and Algernon Blackwood, actually subscribed to its views. Hinton, who wrote a number of "scientific romances" himself, was a post-Christian altruist who speculated that spiritual agencies might work by means of the fourth dimension and believed in something like eternal return.
Some Christians of the late Victorian era, disconcerted by the advance of materialism, attempted to colonize the fourth dimension themselves. For other Christians, such as the liberal theologian Edwin Abbott Abbott (author of Flatland: A Romance of Many Dimensions, a book much admired by Hinton), higher spacial dimensions were merely a metaphor for gradual way in which the human mind must approach divine truths.
I have in my hands a Dover edition of Speculations on the Fourth Dimension: Selected Writings of Charles H. Hinton, which includes several of Hinton's scientific romances. It's edited and has an excellent introduction by Rudolph v.B. Rucker, also known as Rudy Rucker, author of the Ware Tetralogy and a modern tribute to Flatland and all-around sci-fi author of note. So no doubt I'll soon be posting about all of this yet again.
My post on four-dimensional arts and crafts includes an account of my building the sections and net of a 120-cell. More recently, I've printed and built the sections and net of a 24-cell, which is a regular four-dimensional polytope built from twenty-four octahedra.
The sections proceed as follows, with colors given as the craft paints I bought at Wal-Mart: (I) the octahedral cell at the "south pole" (Parchment); (II) the truncated octahedral section cut by a hyperplane through the midpoints of the edges "above" the south pole (Parchment and Real Brown); (III) the cuboctahedral equatorial section cut by a hyperplane through the set of vertices to which these edges connect (Look At Me Blue and Real Brown); (IV) the truncated octahedral section analogous to Section II but in the "northern hemisphere" (Look At Me Blue and Real Brown); and (V) the octahedral cell at the "north pole" (Coffee Latte).
The net has the "south pole" at the center and the "north pole" at the base. For reasons fully known only to my subconscious, but partly inspired by Dalí's painting above, I decided to model it after traditional depictions of the Hindu god Shiva as Nataraja or Lord of Dance, with three-fold rotational symmetry.
Shiva is the destroyer, and his dance is the cosmic dance of creation / destruction. That puts me in mind of the line from the Bhagavad Gita, uttered by Krishna, quoted by Robert Oppenheimer, and used by me in the title of a short story: "Now I am become Death, destroyer of worlds."
