In April 1934, the 'Just Judges' panel was stolen from the Saint Bavo Cathedral in Ghent, Belgium, leaving behind an empty space that remains to this day. The investigation, which has never been officially closed, centered on a local stockbroker named Arsène Goedertier, who claimed on his deathbed to possess the secret of the painting's location. Despite numerous searches of his office, the cathedral grounds, and various urban sites, the original panel has never been recovered. Today, the case remains an open mystery, fueled by conflicting theories ranging from hidden storage within the church to secret burial sites beneath public squares, while a modern replica serves as a placeholder for the missing masterpiece.
The Timeline of the 1934 Saint Bavo Cathedral Theft
The Ghent Altarpiece, a masterwork completed in 1432, suffered a critical loss on 10 April 1934, when the 'Just Judges' panel was surreptitiously removed from the Saint Bavo Cathedral. According to records from The Guardian (2013), the theft was accompanied by a ransom note claiming the panel was taken as a protest against the Treaty of Versailles, which had allegedly removed the art from Germany previously. During the Second World War, the search intensified as German authorities and Nazi agents sought the treasure in 1942. With the investigation failing to yield the original, a replacement panel was commissioned and installed in 1945 by the restorer Jef Van der Veken, as noted by the Mercury News (2012).

Examining the Evidence Left by Arsène Goedertier
Investigators primary suspect was Arsène Goedertier, a local man whose deathbed confession remains the most significant lead in the case. As reported by Wikipedia (2024), Arsène Goedertier told associates, 'I alone know where the Mystic Lamb is. The information is in the drawer on the right of my writing table, in an envelope marked mutualité.' Despite this, a police search of his office yielded only ransom letters and no physical evidence of the artwork. Additional investigations, such as those conducted by German art detective Heinrich Köhn in the 1940s, hypothesized that the panel was actually hidden within the walls or structures of the Saint Bavo Cathedral itself, a theory that continues to influence modern researchers.
The Leading Perspectives on the Lost Panel Location
Historical researchers and detectives often split their focus between two primary theories. One school of thought, supported by authors like Marc de Bel and Gino Marchal, suggests the work remains hidden in the city, specifically near the Kalandeberg square in Ghent. As stated by Gino Marchal in 2018, 'Until we find it, it is just a theory, but it is based entirely on facts.' A competing perspective holds that the confession of Arsène Goedertier was the absolute truth, and that the failure to recover the painting lies in an inability to interpret his vague, final clues—such as his mention of a 'desk, key, closet, health service folder'—correctly. Neither theory has yet been validated by the recovery of the physical object.
The Current Status of the Open Police Investigation
Although decades have passed, the disappearance of the 'Just Judges' is not a closed file. Officials in Belgium have maintained an active, albeit stagnant, interest in the case. According to remarks by former Ghent mayor Daniël Termont in a 2018 interview with The Guardian, the investigation into the theft has never been formally concluded, and local police continue to hold the file open. The search is hampered by the passage of time and the speculative nature of existing leads, which frequently require disruptive and costly excavations in historic areas of Ghent that have so far provided no results.
Why the Masterpiece Remains Lost to History
The primary obstacle to solving the mystery is the absence of concrete physical evidence linking any specific location to the stolen panel. While theories about the cathedral or the Kalandeberg square persist, they remain speculative and lack the corroboration needed for a definitive recovery. The mystery persists because the only person who claimed to know the location, Arsène Goedertier, died without providing verifiable coordinates or physical proof. Without new, actionable intelligence, the search relies on a mixture of historical analysis and educated guessing, leaving the 'Just Judges' as one of the most famous missing artifacts in the world.
