Item #: SCP-XXXX
Object Class: Safe Neutralized Euclid
Special Containment Procedures: SCP-XXXX is to be wrapped in opaque cloth and contained within a standard inanimate-objects locker in Site ██. In accordance with standard protocol for direct-exposure line-of-sight cognitohazards, SCP-XXXX is to be kept under constant real-time video surveillance whenever it is removed from its locker for any purpose (maintenance, analysis, experimentation, etc.).
Personnel above D-Class may not be exposed to SCP-XXXX without the written permission of at least one Level 4 personnel. Unnecessary exposure is highly discouraged.
As of █/██/20██, SCP-XXXX is considered neutralized. An exposure test is to be performed each day for the next month, then once per week thereafter, to confirm that it is still neutralized.
Following the events of Addendum XXXX-2, SCP-XXXX is to be tested weekly to confirm its authenticity. If the test fails, SCP-XXXX must be reacquired with highest priority.
Description: SCP-XXXX is a replica of René Magritte's famous painting The Treachery of Images. Unlike the original, SCP-XXXX is a direct-exposure antimemetic cognitohazard to anyone who observes it. Photos or videos of SCP-XXXX have the same effect.
Subjects who have viewed SCP-XXXX cease to be able to identify the object depicted in the painting. Furthermore, they also lose the ability to identify any similar object, whether depicted in art or as a physical object. Exposed subjects will refuse to accept any explanation of such an object's identity, whether correct or incorrect. This applies even if the subject did not know the object's identity before viewing SCP-XXXX.
All attempts to revert this effect, including the use of amnestics, have proven ineffective.
SCP-XXXX was discovered at a local art show along with a number of other replicas of well-known paintings. An estimated ███ people were exposed to the cognitohazardous effect before the paintings were purchased by Foundation agents. None of the other paintings displayed any anomalous properties.
During subsequent interrogation, the seller insisted SCP-XXXX must have been placed into his display by someone else, and that he would "refuse, on principle, to paint replicas of anything by that pretentious [EXPLETIVE]."
Addendum XXXX-1: On ██/██/20██, routine experimentation with SCP-XXXX revealed that its anomalous properties had vanished. This was verified repeatedly over a period of multiple days, leading researchers to conclude that the object was neutralized, though how this occurred is still unknown. Accordingly, the object formerly classified as SCP-XXXX remains in storage, since its anomalous properties could re-manifest in the future.
Addendum XXXX-2: Further analysis of SCP-XXXX over the next few weeks revealed that it was no longer the same object originally acquired by the Foundation, but rather the original Magritte painting itself. A review of surveillance footage showed no abnormalities, leading researchers to suspect that SCP-XXXX somehow swapped with the real painting, which was on display at the time at the ███ ███████ ██████ Museum of Art.
Foundation agents were dispatched to the museum to investigate. After interviewing patrons and museum staff, many of whom were unable to identify the object portrayed in the painting, it was confirmed that the display copy of "The Treachery of Images" was actually SCP-XXXX. ████ additional people were estimated to have been exposed. SCP-XXXX was tentatively reclassified as Euclid.
SCP-XXXX was recovered and returned to Site ██ and the original returned to the exhibit in its place. Document XXXX-A5, handwritten in the same style as the text on the painting, was found taped to the back of the frame.
Document XXXX-A5:
Art is a treacherous tool.
A simple painting can make you question things you always assumed to be true.
Are we cool yet?
