Like Williams’ first novel War in Heaven, the main business of Many Dimensions is an extended scrimmage over a holy relic: in this case, the Stone of the Wise that was set in the crown of King Solomon. Continuity with the earlier book is provided in the person of a single character, the sadistically inquisitive Sir Giles Tumulty. Other key characters include English Chief Justice Lord Christopher Arglay, who seems to be a sort of secular adeptus major undergoing an initiation to adeptus exemptus in the course of the novel, and his personal secretary Chloe Burnett who meanwhile climbs the entire mystical ladder from neophyte to magister templi.
Many of the chapter titles have a clever ambivalence. “The Refusal of Lord Arglay” could mean that Arglay is refused or refusing. Similarly, “The Discovery of Giles Tumulty” could mean that Tumulty is discovered or discovering.
Many Dimensions functions with some effectiveness as a parable regarding the magical will. The overt reflection on this topic is quasi-incidentally remarked in a quotation from 13th-century English jurist Henry of Bracton: Attribuat igitur rex legi, quod lex attribuit ei, videlicet dominationem et potestatem. Non est enim rex ubi dominatur voluntas et non lex. (214) Williams doubtless contemplated this maxim in a theological, rather than a magical sense, but the action of his novel is open to both.
There is a surprisingly sympathetic treatment of Islam in this book, creating a contrast with the sort of moronic Islamophobia in which Williams’ friend C.S. Lewis trafficked in the form of his villainous Calormenes. Although Williams was the author of works of Christian theology, his fiction shows him to have a generous religious imagination, including a warmth toward conscientious skepticism. This latter is on full display in the character of Lord Arglay, who at one point describes the Christian Passion as “one of the myths of our race.”
