As a literary device or artistic form, an allegory is a narrative or visual representation in which a character, place, or event can be interpreted to represent a meaning with moral or political significance.
Authors have used allegory throughout history in all forms of art to illustrate or convey complex ideas and concepts in ways that are comprehensible or striking to its viewers, readers, or listeners.
The origins of allegory can be traced at least back to Homer in his "quasi-allegorical" use of personifications of, e.g., Terror (Deimos) and Fear (Phobos) at Il.
In classical literature two of the best-known allegories are the Cave in Plato's The Republic (Book VII) and the story of the stomach and its members in the speech of Menenius Agrippa (Livy ii.
This allegory is, on a basic level, about a philosopher who upon finding greater knowledge outside the cave of human understanding, seeks to share it as is his duty, and the foolishness of those who would ignore him because they think themselves educated enough.

In the late 15th century, the enigmatic Hypnerotomachia, with its elaborate woodcut illustrations, shows the influence of themed pageants and masques on contemporary allegorical representation, as humanist dialectic conveyed them.
The denial of medieval allegory as found in the 12th-century works of Hugh of St Victor and Edward Topsell's Historie of Foure-footed Beastes (London, 1607, 1653) and its replacement in the study of nature with methods of categorisation and mathematics by such figures as naturalist John Ray and the astronomer Galileo is thought to mark the beginnings of early modern science.
According to Henry Littlefield's 1964 article, L. Frank Baum's The Wonderful Wizard of Oz, may be readily understood as a plot-driven fantasy narrative in an extended fable with talking animals and broadly sketched characters, intended to discuss the politics of the time.
"[25] J. R. R. Tolkien's The Lord of the Rings is another example of a well-known work mistakenly perceived as allegorical, as the author himself once stated, "...I cordially dislike allegory in all its manifestations, and always have done so since I grew old and wary enough to detect its presence.
"[26] Tolkien specifically resented the suggestion that the book's One Ring, which gives overwhelming power to those possessing it, was intended as an allegory of nuclear weapons.
Then Tolkien went on to outline an alternative plot for "Lord of The Rings", as it would have been written had such an allegory been intended, and which would have made the book into a dystopia.
