Everything must change, so the saying goes. Art is no exception and folk art has always been particularly in tune with cultural shifts being, by its nature, by the people for the people.
So it is with the Mexican sculptural tradition of the Tree of Life or Árbol de la vida. It has gone from an instructional tool of religious imposition to contemporarily, something quite different. Yet it wasn't itself an art form which sprang spontaneously in to being with the arrival of people from the Old World: its roots are much older.
