Cantiga 29 of the Cantigas de Santa Maria of Alfonso X

The Images of the Virgin Mary at Gethsemane
In Gethsemane there were images of the Virgin that were not paintings.
They were not sculptures either.
The images showed the Virgin and Child; both were well executed and accurately proportioned.
The Virgin made these images glow.
This proves that she has power over all things and can bring light from darkness.
God chose to depict her features on the stones to demonstrate that all creatures should honour her because he came down from heaven to take on flesh in her.
