The girl escaped the riots by traveling through mesas, prairies, and deserts. In the sanctuary of an abandoned white mission crumbling at the foot of the iron-gray mountains, she met the almost immortal archivist. The shadow introduced himself with immaculate manners and a gentleness she had never seen before. The man had burning, green eyes full of mystery and tenderness, like a young child still amazed and excited by the world. Dressed in a black frock, a white ruff collar, and long leather boots, she thought he looked like a figure from a history textbook or a character in a renaissance play. The archivist said that he had sailed on galleons six hundred years ago. The interior of the mission was practically a museum exhibit from bygone times. There were bookshelves of ancient codices, polished oak tables covered with manuscripts and charts, and coffers stuffed with relics. They stood over a table, where he showed her pictures resembling an unknown continent. She saw it begin as an almost formless mass in blank, bone-white oceans and acquire firmer and bolder edges of ink, more promontories and inlets, more precise curves. She asked him what the drawings were about. The archivist explained that they were the diagrams of thought experiments, or a succession of related thought experiments that had been acted out in space and time. And he spoke of handwritten thinking machines, diagrams, mind maps, memory palaces illuminated in old manuscripts, geometric drawings with proofs, astronomical tables and charts used for calculation. One by one, he showed her more pictures. Something was beginning to form in her mind. At last, she saw that the drawings were nothing more than maps of her own land. The archivist looked into her eyes with suffering or desperation and asked her what the thought experiments meant.
