What are the motifs in One Hundred Years of Solitude by Gabriel Garcia Marquez?

Time is a recurring idea in the book. Throughout the novel, time moves in ways that are nonlinear. When Ursula sees Aureliano Triste planning for the railroad just as his grandfather Jose Arcadio planned Macondo's development, it "confirmed her impression that time was going a circle." She makes similar observations about her great-grandson Jose Arcadio Segundo, whose actions resemble those of her son Colonel Aureliano.
