The palimpsest is a parchment that is reused several times, that is to say that old texts have been erased and then a new text has been entered and this several times.
The old erased texts nevertheless let appear some traces, which gives an impression of superimposition of writings.

The superimposed writings lose their sign values referring to a meaning but take on a uniquely expressive and emotional value thanks to the strength of the line and the contrast of the colors.
