Jorge Luis Borges

Jorge Luis Borges was a human writer from Earth. He wrote the novel O Time Your Pyramids, which was subsequently lost; though the Doctor thought he owned the only surviving copy, he found another in the Librarinth on the Needle. (PROSE: The Infinity Doctors)

Diego Rivera allowed him to read the Rivera Manuscript, which he compared unfavourably to the Saragossa manuscript. (PROSE: The Book of the War)
