Symbolism, Imagery, Allegory
We know, we know – what in the world is a bone spur? In short, it’s a painful injury DiMaggio had in his heel right around the time The Old Man and the Sea takes place. DiMaggio ended up being completely successful despite his handicap – kind of like the old man. DiMaggio becomes a symbol for withstanding pain, for endurance throughout suffering, to achieve the impossible and lots of other grand notions the old man emulates.
