4 symbols in the story a old man at the bridge?

In "The Old Man at the Bridge" by Ernest Hemingway, four significant symbols are present: the old man himself represents innocence and vulnerability in the face of war; the bridge symbolizes a crossing between safety and danger; the animals he cares for, particularly the goats, signify the lost simplicity and peace of life disrupted by conflict; and the landscape, marked by the war, highlights the desolation and despair that accompanies human strife. Together, these symbols convey the themes of loss, displacement, and the impact of war on individuals and their surroundings.
