This story, entitled El ramito de romero, was published in 1883 in the book Creaciones, and its content is strikingly similar to Borges' text.
At the beginning of the story, he is mourning the recent death of Beatriz Viterbo, a woman he loved, and he resolves to stop by the house of her family to pay his respects.
Over time, he comes to know her first cousin, Carlos Argentino Daneri, a mediocre poet with a vastly exaggerated view of his own talent who has made it his lifelong quest to write an epic poem that describes every single location on the planet in excruciatingly fine detail.
Left alone in the darkness of the cellar, the narrator begins to fear that Daneri is conspiring to kill him, and then he sees the Aleph for himself: On the back part of the step, toward the right, I saw a small iridescent sphere of almost unbearable brilliance.
I saw the teeming sea; I saw daybreak and nightfall; I saw the multitudes of America; I saw a silvery cobweb in the center of a black pyramid; I saw a splintered labyrinth (it was London); I saw, close up, unending eyes watching themselves in me as in a mirror; I saw all the mirrors on earth and none of them reflected me; I saw in a backyard of Soler Street the same tiles that thirty years before I'd seen in the entrance of a house in Fray Bentos; I saw bunches of grapes, snow, tobacco, lodes of metal, steam; I saw convex equatorial deserts and each one of their grains of sand...[3] Though staggered by the experience of seeing the Aleph, the narrator pretends to have seen nothing in order to get revenge on Daneri, whom he dislikes, by giving Daneri a reason to doubt his own sanity.
