The word "trough" is used in literature in both literal and symbolic ways, serving not only as a mundane object for feeding or washing but also as a metaphor for human conditions and social commentary. In ancient epics like Homer's works [1, 2] and mythological narratives from the Younger Edda [3, 4, 5, 6], the trough appears in scenes of daily sustenance and ritualistic settings, underscoring its role as a container of life's essentials. At the same time, authors like Chekhov [7, 8, 9, 10] and Hardy [11, 12] use the trough to evoke domesticity, labor, and even chaos, as seen in vivid descriptions of everyday struggles and symbolic disarray. In proverbial and allegorical texts [13, 14, 15], the trough becomes an instrument in conveying wisdom about human nature and fate, while other works, from Verne's vivid depictions of nature [16] to Carlyle’s historical reflections [17], illustrate its versatility as both an object and a metaphor reflecting society’s ebb and flow.
