The word "trestle" has been employed in a variety of literary contexts, both as a literal structure and as a potent symbol. In some works, the trestle is a tangible element of the physical world—a bridge spanning a deep gorge [1] or a short-cut home as night falls [2], its tremors underscoring the precariousness of travel [3] and the transitory nature of man-made structures [4]. In contrast, other authors use the trestle, or trestle-board, metaphorically to represent foundational ideas, such as the underpinnings of natural and moral law, or the individual tasks assigned by a higher architect [5, 6, 7, 8]. Even when the term is descriptive—illustrating, for example, the intricate, fiber-like construction that gives color to an iris [9]—it carries a resonance that elevates its meaning beyond mere physicality. The varied uses of "trestle" reveal its flexibility as both a concrete image and a symbol laden with deeper philosophical significance.
