I recently read an article detailing Marquez's relationship with his grandparents, with whom he lived for the first eight years of his life. After our class discussions, I'd learned that his grandparents shaped his writings, specifically One Hundred Years of Solitude, but I was unsure exactly how they did so.
HIS GRANDFATHER: Nicolas Marquez
At one point, he was an army colonel! (Colonel Aureliano Buendia, perhaps?)
He also was a jeweler and a tax collector.
According to author Gentile, "Nicolás taught Gabo about history, war, and the banana plantation that dominated the town." Marquez focuses on all three of these topics in One Hundred Years of Solitude.
HIS GRANDMOTHER: Tranquilina Iguarán
First of all, her name was Iguarán. Ursula's last name is the same.
Secondly, she helped the family financially by selling vegetables and homemade sweets. Ursula also sold homemade candy.
Apparently, Tranquilina anticipated doom quite frequently and took many steps to avoid it. Like Ursula, her superstitions often got the best of her.
In his memoir, Marquez implies that without his grandfather, he likely would've become lost in Tranquilina's magical view of the world. Still, Marquez points out that although he remained grounded in the realistic world, "his grandmother's world" was hard to resist.
In a sense, Marquez's style of magical realism was an attempt to blend Nicolas's and Tranquilina's outlooks into one, to reconcile them. Although Marquez only lived with his grandparents for eight years, their unique perspectives left a mark on Marquez--one that manifests itself in One Hundred Years of Solitude. Grandparents possess a special power; in Marquez's case, their influence lives on in a novel read and respected by millions.
