Piranesi’s Star Maps are hand-made records of the stars and constellations visible from the House, created with paper, pencils, and other stationery. They make his patient observation portable and communicable: he brings the maps to The Other, who studies them for information relevant to a ritual. Yet the maps also belong to a larger change in Piranesi’s understanding. After an encounter with the beauty of the moonlit House, he no longer considers the pursuit of the Great and Secret Knowledge worth organizing his life around, even as The Other continues to treat astronomical observation as a means to that end.

Making and Using the Maps

Piranesi’s supplies include twelve large sheets of paper specifically intended for Star Maps, along with pencils, a ruler, envelopes, and other stationery. The list places the maps among the practical tools of his life in the House: they are made by hand, as part of sustained observation rather than as an abstract or purely theoretical project.

On the twentieth day of the sixth month in the year the albatross came to the south-western halls, Piranesi records the constellations and stars visible from the Eighty-Eighth Western Hall. The Full Moon declines westward, the light in the hall diminishes, and the constellations grow brighter in the window opposite the doorway. He makes notes of what he can see, sleeps for a few hours at dawn, and then begins the journey home. The maps therefore preserve observations tied to a particular place and changing sky, not a timeless inventory of the heavens.

A Record Shared with The Other

Two days later, Piranesi takes his Star Maps to the Second South-Western Hall, where he finds The Other leaning against an empty plinth. When Piranesi describes his earlier visit to the One-Hundred-and-Ninety-Second Western Hall, The Other dismisses the account of its statues and asks instead what stars were visible. Piranesi opens a map on the plinth and identifies the Rose, the Good Mother, and the Lamp-post, followed toward morning by the Shoemaker and the Iron Snake. These names are his own, showing how the charts join careful observation to a personal system of naming.

The Other examines the map and makes notes with his shining device. Asked whether any star is particularly bright, Piranesi points out one belonging to the Good Mother, at the tip of her extended arm. The Other calls this information valuable: he has decided to go to that room and perform a ritual, despite the risks of travelling farther into the labyrinth than he has before. He asks Piranesi to return and establish which constellations can be seen at different times of year. The map has thus become more than Piranesi’s private record; it supplies observations The Other intends to use in an undertaking with potentially immense rewards.

Observation and the Great and Secret Knowledge

The maps stand at the point where the two men’s purposes diverge. The Other interprets the brightest star as a fitting symbol for the greatest knowledge and treats the chart as useful intelligence for reaching it. Piranesi, meanwhile, has recently concluded that he no longer intends to spend his time searching for the Great and Secret Knowledge. The conclusion came to him as a revelation while returning from the One-Hundred-and-Ninety-Second Western Hall, whose moonlight, calm, and statues seemed to disclose a value the search for knowledge risked overlooking.

For Piranesi, the danger is that the House will be treated as a riddle whose worth can be extracted once its answer is found. The Other’s request demonstrates that the maps can be recruited into precisely that instrumental project: a star’s position becomes a clue, and a chart becomes a guide toward a ritual. But Piranesi’s own act of mapping also records attention to the House as it appears, in a particular hall and under a particular moon. The maps consequently hold two uses in tension—evidence for a search aimed at acquiring power, and an expression of attentive engagement with a world whose beauty and worth do not depend on being solved.
