In Miguel de Cervantes' "Don Quixote," a knight is depicted as he cleans his armor, reflecting his dedication to his noble pursuits. He seems to be in the quest for a lady to inspire his love, emphasizing the importance of romance in a knight's life. This notion suggests that a knight devoid of love lacks vitality, much like a tree that is barren and without life.
The metaphor highlights that love is essential for a knight's purpose and passion. The imagery of a lifeless body further illustrates the void that an absence of love creates. In this context, the knight's quest for a beloved is not merely about romantic attachment but about the fulfillment of his identity and essence as a knight.
