Through the “Lapis Tiburtinus”, the Roman travertine, the ancient Latins created the very face of their cities, remodeled the typical landscapes of the Urbe. On one side the cold stone, the primordial material, on the other the pencil, the tool through which people’ ideas can take shape becoming a drawing - both symbolized by the word Lapis. Upon closer inspection, the symbolic nature of travertine appears immediately clear: its texture tells us of a story of torrents and brooks through its veins, of hills and crevices, of mineral islands in a sea of rock, surrounded by strange animals and fossil plants belonging to a distant time. The surface of Travertine is a landscape on its own, at its heart it preserves, albeit in an embryonic form, all the elements of the environment in which it was formed and of which it is an integral part. A microcosm in the image of the macrocosm.
