García Márquez's grandmother, Doña Tranquilina Iguarán Cotes, played an influential role in his upbringing. He was inspired by the way she "treated the extraordinary as something perfectly natural." The house was filled with stories of ghosts and premonitions, omens and portents, all of which were studiously ignored by her husband. According to García Márquez she was "the source of the magical, superstitious and supernatural view of reality". He enjoyed his grandmother's unique way of telling stories. No matter how fantastic or improbable her statements, she always delivered them as if they were the irrefutable truth. It was a deadpan style that, some thirty years later, heavily influenced her grandson's most popular novel, One Hundred Years of Solitude.
He has experimented with less traditional approaches to reality, so that "the most frightful, the most unusual things are told with the deadpan expression". A commonly cited example is the physical and spiritual ascending into heaven of a character while she is hanging the laundry out to dry in One Hundred Years of Solitude. The style of these works fits in the "marvellous realm" described by the Cuban writer Alejo Carpentier and has been labeled as magical realism.
