I first caught a glimpse of the power of allusions when I read The Lord of the Rings for the first time in Grade Six. As much as I loved the characters and was swept along by Tolkien’s sense of timing, what really struck me was all the passing references to thousands of miles of geography and thousands of miles of history. I didn’t know, then, that Tolkien had built up this material over decades. What mattered to me was the illusion of added depth created by the allusions. You didn’t need to know all the details — in fact, as subsequent Tolkien publications of the back story showed, you were usually better off if you didn’t, because what seemed magically suggestive in passing became unavoidably disappointing in detail. But, even at that age, I recognized an effective literary technique when I saw one.
Later, I saw it in a number of other books, including The Worm Ourboros by E. R. Eddison, Conan Doyle’s Sherlock Holmes stories (when unsolved cases are mentioned), and in the Dark Border series by my late friend Paul Edwin Zimmer. So it’s not a new device, even if you won’t find it taught along the memorized definitions of metaphor and metonymy that they teach in high school.
Part of the reason, I suppose, is that, despite the enduring popularity of writers like Tolkien or Conan Doyle, it’s a device used most often in fantasy, which literary critics still distrust because of the whiff of popular culture that rise from them. Moreover, it requires a deft hand, and is harder to observe objectively than something as straightforward as a simile.
Basicallly, however, the art of creating depth through allusions lies in striking the exact balance between suggestiveness and mystery. The allusion has to be comprehensible enough that readers can get some dim understanding of it, but no more.
That lack of detail may seem lazy, yet it’s essential. Because the allusion is incomplete, readers have to fill in the gap themselves with guesswork. By doing so, they are drawn into the story-telling, and become participants in the development of the background.
The idea is the same, I suppose, as Stephen King’s observation that a horror writer has to use the appearance of the monster sparingly. The monster may be scary, King says, but its actual appearance will never match what the reader imagined. The writer may show a ten foot monster, but what the reader imagined was a sixty foot monster, and the reality will disappoint.
In the same way, an allusion explained is an allusion lost. When Tolkien mentions Lúthien and Beren, you know that it’s an unhappy love story and somehow applies to Aragorn. The tale in the appendices or in The Simarillion may be interesting in its own right, but it’s not nearly as poignant as the tale you imagine when you first read the allusion.
In the same way, has anyone ever read one of the pastiches that explains the giant rat of Sumatra that is half as interesting as the passing mention of the unwritten story that Dr. Watson makes in passing?
The technique is used mainly in fantasy, but it can be used more conventionally, too. For example, in Roger Zelazny’s This Immortal, the title character explains that he is late for an event because he was attending the birthday party of a friend’s young daughter. As Zelazny himself observes, the line of explanation is technically unnecessary. All the same, he kept it in because it suggests that the character has a life beyond what is being told in the page, and that he’s the kind of person who, for all his toughness, would do such a thing. At the cost of maybe fifteen words, Zelazny gets an illusion of depth that enriches his effort. That illusion makes the allusion worth having, always.
