The Fourth Dimension

Alan Moore's Jerusalem (London, 2016), pp. 512-514 refers to dimensional theoreticians, Hinton and Abbot. Artists and spiritualists got interested in the fourth dimension (p. 514), as did writers:

One of the two minor characters in "The Visitor" is a researcher testing "'...Dunne's theory that dreams can foretell the future.'" (p. 169)

There is a very select list of literary works that refer to Dunne's theory:

JW Dunne knew HG Wells, sharing interests in time and aircraft;
Dunne's An Experiment With Time refers to Wells' The Time Machine;
Wells' The Shape Of Things To Come refers to An Experiment With Time.

Thereafter, works based on An Experiment With Time include:

The Gap In The Curtain by John Buchan;
Time And The Conways by JB Priestley;
Tom's Midnight Garden by Philippa Pearce.

And works crucially referring to Dunne include:

"The Dark Tower" by CS Lewis;
"The Visitor" by Poul Anderson.
