Origin and history

The pseudo-polisor of Jaignes is a large slab of sandstone measuring 2.70 m by 1.30 m, discovered in 1865 during the creation of the cemetery of Jaignes in Seine-et-Marne. Originally identified as a Neolithic polisher because of its grooves and cupules, it was classified as a historical monument in 1909. Subsequent studies have shown that these engravings, which were disorientated and accompanied by various lines, did not correspond to a polishing tool, but rather evoked a rock art similar to that of the Fontainebleau forest.

The stone was reported in 1899 by P. Reynier, then moved near the village church. Although its original use remains uncertain, its heritage protection continues as a testimony to the artistic or symbolic practices of Neolithic in Île-de-France. The small and unstructured grooves and cups exclude any polishing utility, contrary to what its name suggests.

Today owned by the municipality of Jaignes, the monument is accessible near the church (1 Church Street). Its 1909 ranking reflects the archaeological knowledge of the time, while subsequent research, such as that of Alain Bénard in 2009, allowed to recontextualize its importance in the local megalithic heritage.
