The marks etch the stone, hollowing out part of the surface while simultaneously draw margins, boundaries, exchange zones between linear elements and large areas of matter.

Like a map, the marks engraved on the stone are 'paths' representing the repetition of the time and space.

"Stone is a huge canvas, an immense aesthetic territory, on which one can write one's own map that is the result of the interaction between man and nature."
