In the late 1950s, Borges gradually fell into the deep blindness inherited from his family. Because poetry has rhyme and rhythm, it is easy to connect poems from memory while blind. Borges began to write a lot Writing metrical poems, novels were completely put aside. It was not until the 1970s that he entered the second peak period of novel writing with the short story collection "The Brody Report". What is very different from the first peak period of novel writing is that in the second peak period, he wrote novels and poems at the same time. Although thematically his short stories during this period still focused on some of his lifelong "metaphysical interests": Gnosticism, Kabbalah, duality, infinity, death, memory and time, in terms of technique But it is combined with the plainness and compression that he honed in his poetry of the same period, making the novels of this period, especially the collection "The Book of Sand", appear more restrained, concise and calm. The "interpenetration of styles" presented is the clearest.
