At about 8.47pm on the evening of 15 August, while tens of thousands of worshippers filled the streets of central Messina for a religious festival, at least two men cut through the fencing surrounding the regional museum, located a few miles to the north on the outskirts of the Sicilian harbour city.
Capitalising on the fact that the streets around the museum were unusually quiet, the men forced open a side door with a crowbar, gaining direct access to a display case containing the five surviving panels of the Renaissance master Antonello da Messina’s polyptych Polittico di San Gregorio, his most important work, and a small double-sided painting. Undisturbed, they removed the works from the building and fled.
