Each thing (a mirror's face, let us say) was infinite things, since I distinctly saw it from every angle of the universe. The Aleph's diameter was probably little more than an inch, but all space was there, actual and undiminished. At first I thought it was revolving then I realised that this movement was an illusion created by the dizzying world it bounded. 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. Though by now he believes Daneri to be quite insane, the narrator proposes without waiting for an answer to come to the house and see the Aleph for himself. Daneri becomes enraged, explaining to the narrator that he must keep the house in order to finish his poem, because the cellar contains an Aleph which he is using to write the poem. Later in the story, a business on the same street attempts to tear down Daneri's house in the course of its expansion. 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. At the beginning of the story, he is mourning the recent death of a woman whom he loved, named Beatriz Viterbo, and resolves to stop by the house of her family to pay his respects.

As in many of Borges' short stories, the protagonist is a fictionalized version of the author. The story traces the theme of infinity found in several of Borges' other works, such as 'The Book of Sand'. Anyone who gazes into it can see everything in the universe from every angle simultaneously, without distortion, overlapping, or confusion. In Borges' story, the Aleph is a point in space that contains all other points.
