Renaissance Panels by Antonello da Messina Stolen from Sicilian Museum on Ferragosto Holiday
Thieves bypassed alarm systems and broke into a security display box at the MuMe (Regional) museum in Messina, Sicily, making off with four painted wood panels attributed to the Renaissance master Antonello da Messina during Italy's Ferragosto summer holiday on 15 August 2026.
The stolen works belong to the San Gregorio Polyptych — an altarpiece measuring 170 cm by 203 cm and composed of five wooden panels, according to Reuters. A polyptych is a multi-panel painting, typically hinged for use as a church altarpiece. Three of the five panels were taken, along with a separate small panel known as a tavoletta, for four panels in total, the Italian news agency ANSA reported.
The gang had actually removed all five polyptych panels from their frame but abandoned two behind a low wall while fleeing, Le Monde reported. Passers-by noticed the discarded panels outside the museum building, ANSA said. Those two recovered panels were left on the wall; the remaining four are still missing.
The Associated Press described the stolen works as worth millions of euros. No specific valuation has been published. Antonello da Messina, born in Messina in the early 1430s, is credited with bringing oil-painting techniques perfected in the Netherlands to Italian Renaissance art, and his surviving output is small — making every panel significant to the city where he was born and worked.
The timing was no accident. Ferragosto, the 15 August national holiday that shuts down much of Italy, left the museum and surrounding streets quieter than usual. Italian newspaper la Repubblica's Palermo edition called the theft a sensational strike that disrupted the holiday weekend.
As of 17 August 2026, Italian prosecutors were investigating whether the thieves had help from the inside. ANSA reported that investigators are searching for a "basista" — an accomplice with knowledge of the museum's security layout who may have guided the gang past the alarms and to the display case.
The MuMe museum houses one of the most important collections of Antonello da Messina's work in the world. The San Gregorio Polyptych, painted around 1473, is considered one of the artist's major undertakings. That four of its panels and the separate tavoletta are now in unknown hands is a loss the city feels directly: the works are part of Messina's identity, not just its tourism.
Recovering stolen art is notoriously slow. Italy's Carabinieri cultural-heritage protection unit, a specialised police division, maintains one of the world's largest databases of stolen artworks, but decades can pass before missing pieces resurface — sometimes at auction, sometimes in private homes, sometimes not at all. For now, the investigation focuses on the museum's own corridors.
