Four cylindrical elements of travertine, with a rough surface like large rocks, alternate among the palm trees placed on a modelled green area which ideally unites them, creating an emotional viaticum connected to the sacredness of nature. Four symbolical “mandala”, instruments of antique knowledge intended to undertake a path of awareness inside of yourself, unified metaphorically by a green passage, at the beginning of those cognitive paths. The antique palm trees pruned and purified welcomes the stones with transcendent harmony: a restoration of ancestral natural equilibrium.
