Prohibition on reading 16’s messages

The prohibition on reading 16’s messages is the Other’s warning that 16’s words are dangerous in any form and that reading them could make Piranesi mad. It turns communication into a hazard: Piranesi must contend not only with the threat attributed to the message but also with his own powerful curiosity. His attempt to destroy the writing without reading it is therefore both an act of obedience and a revealing failure of resolve.

The Warning and Its Stakes

The warning follows Piranesi’s discovery of words chalked on the pavement of the Sixth North-Western Hall. When he asks the Other whether 16 can impart madness through written words and whether he should have read them, the Other replies that 16’s words are dangerous whatever form they take. He says it would have been better not to read the message, but does not blame Piranesi: the written communication surprised them both, and even the Other had not considered that possibility. He frames the moment as critical and urges greater care.

The explanation makes the prohibition more than a general instruction to avoid 16. It specifically treats the written message as a means of influence, so that even an encounter with its words may seem to carry consequences. The Other’s warning establishes the rule that governs Piranesi’s response, while leaving him to manage the physical evidence himself. The danger is presented through the Other’s claim; the supplied scenes show Piranesi acting on that claim, rather than independently establishing that reading itself causes madness.

Curiosity and the Unread Message

When Piranesi later sees 16 writing in the Sixth North-Western Hall, the sight unsettles the distance the warning is meant to enforce. 16 writes for a long time, and Piranesi finds himself pleased by the length of the message. He immediately questions that reaction: its length should not matter if he is not going to read it. Yet he recognizes that part of him considers madness almost an acceptable price for knowing what 16 has written.

This moment gives the rule its inward conflict. Piranesi does not simply face a forbidden text; he feels its attraction while rehearsing the reason to resist it. The message’s physical presence makes the warning difficult to obey: as long as the writing remains, he expects to feel a strong urge to read it. Curiosity thus becomes part of the danger, even before he decides what to do with the words.

Erasure and Its Compromise

Piranesi decides that destroying the message is his only option. He returns to the Third Northern Hall for an old shirt and chalk, tears the ragged shirt in two, and goes back to the Sixth North-Western Hall. He ties one half over his eyes as a blindfold and uses the other to sweep across the pavement, trying to erase 16’s writing without looking at it.

The procedure is careful but incomplete. After a couple of minutes, Piranesi removes the blindfold and finds that fragments remain. He has intended to eliminate the temptation without exposing himself to the message, but his action has not cleanly achieved either aim: the writing still exists in part, and he has looked at some of it. He sees the words identifying a room with statues of Minotaurs. Instead of continuing to read, he resolves to erase what remains, showing how the warning continues to direct his conduct even after his first attempt fails.

Piranesi kneels and writes a reply to 16. He says that he has erased the message without reading it, insists that the words have not touched him and that he has not been made mad, and declares that 16’s plan has failed. He also warns that the Other will try to kill 16 if 16 remains in their halls, and urges 16 to return to the far-distant halls. The reply demonstrates the contradiction built into the prohibition: Piranesi refuses to receive 16’s communication, yet answers it and reveals that the Other possesses a gun. His written response is an attempt to enforce distance from 16 while warning him of an immediate threat.

Later Explanation and Significance

When Sarah Raphael asks whether this was the message Piranesi wiped out, he confirms that it was. Asked why, he explains that Dr Ketterley had told him that 16 was his enemy and that reading the message would make him go mad. Piranesi recalls that he erased it but did not erase all of it because he wanted to read it; he recognizes that this was not logical. Raphael observes that Ketterley made things very hard for him, and Piranesi agrees.

That later account places the prohibition within a relationship of trust and control. Piranesi’s immediate explanation had treated the rule as a safeguard against 16, but his retrospective account identifies Dr Ketterley as the source of the claim that reading would cause madness. The leftover fragments, his concealed reading of part of the message, and his confession of divided motives expose the strain between the instruction he follows and his desire to judge 16’s words for himself. The prohibition therefore shapes not only what Piranesi reads, but also which person’s account of 16 he is initially prepared to believe.
