The story goes that a feudal lord used the derecho de seigneur in the town of O Grove until one day the Grovenses, fed up with suffering these abusos, they hung him from a fig tree in the Monte A Siradella. When the courts asked who had killed El Meco, the united people answered that they had all been. In this way the crime remained unsolved, as everyone went unpunished, and since then all Grovenses are known aso mecos.

This legend was already collected by the Padre Sarmiento In his book Journey to Galicia in 1745. The oral tradition continued to perpetuate the story, until at the end of the 20s of the last century it also became a play by Francisco Franco Calvete.
