According to tradition, it was made in memory of one of the men who worked at the church but fell and died during the construction; scholars have suggested that it may on the other hand simply be a stone that was placed in the wrong direction with the picture lying down instead of standing up.
Segundo a tradición, foi feita na memoria dun dos homes que traballaron no edificio pero caeu e morreu durante a súa construción; os académicos suxeriron que pode ser sinxelamente unha pedra que foi colocada na dirección equivocada coa imaxe recostada en vez de estar de pé.
