The old man of the novella’s title, Santiago is a Cuban fisherman who has had an extended run of bad luck. Despite his expertise, he has been unable to catch a fish for eighty-four days. He is humble, yet exhibits a justified pride in his abilities. His knowledge of the sea and its creatures, and of his craft, is unparalleled and helps him preserve a sense of hope regardless of circumstance. Throughout his life, Santiago has been presented with contests to test his strength and endurance. The marlin with which he struggles for three days represents his greatest challenge. Paradoxically, although Santiago ultimately loses the fish, the marlin is also his greatest victory.
Santiago hooks the marlin, which we learn at the end of the novella measures eighteen feet, on the first afternoon of his fishing expedition. Because of the marlin’s great size, Santiago is unable to pull the fish in, and the two become engaged in a kind of tug-of-war that often seems more like an alliance than a struggle. The fishing line serves as a symbol of the fraternal connection Santiago feels with the fish. When the captured marlin is later destroyed by sharks, Santiago feels destroyed as well. Like Santiago, the marlin is implicitly compared to Christ.
A boy presumably in his adolescence, Manolin is Santiago’s apprentice and devoted attendant. The old man first took him out on a boat when he was merely five years old. Due to Santiago’s recent bad luck, Manolin’s parents have forced the boy to go out on a different fishing boat. Manolin, however, still cares deeply for the old man, to whom he continues to look as a mentor. His love for Santiago is unmistakable as the two discuss baseball and as the young boy recruits help from villagers to improve the old man’s impoverished conditions.
Although DiMaggio never appears in the novel, he plays a significant role nonetheless. Santiago worships him as a model of strength and commitment, and his thoughts turn toward DiMaggio whenever he needs to reassure himself of his own strength. Despite a painful bone spur that might have crippled another player, DiMaggio went on to secure a triumphant career. He was a center fielder for the New York Yankees from 1936 to 1951, and is often considered the best all-around player ever at that position.
Perico, the reader assumes, owns the bodega in Santiago’s village. He never appears in the novel, but he serves an important role in the fisherman’s life by providing him with newspapers that report the baseball scores. This act establishes him as a kind man who helps the aging Santiago.
Martin - Like Perico, Martin, a café owner in Santiago’s village, does not appear in the story. The reader learns of him through Manolin, who often goes to Martin for Santiago’s supper. As the old man says, Martin is a man of frequent kindness who deserves to be repaid.
