Final answer:
The allegorical symbol of a fox represents cunning, cleverness, and strategy, typically signifying the use of intelligence over strength in literature and art.
Step-by-step explanation:
The commonly accepted allegorical symbol of a fox is that of cunning, cleverness, and strategy. Allegory is a narrative technique where characters and events represent broader truths or generalizations about human existence or societal norms. For example, in many stories and fables, foxes are depicted as being sly and able to outwit other characters, which symbolizes the use of intelligence and strategy over brute strength. Similarly, in artworks like those of Marc, where the fox's fierce nature is represented through vivid colors and dynamic brushstrokes, the animal's portrayal could be interpreted as a reflection of wild instincts and the spirit of survival. The abstract representation of the fox through geometric shapes in Marc's painting reflects an artistic exploration of the relationship between reality and interpretation, much like in literary allegories.
