Water, wind and time have formed the dreamlike landscape of the Balze: the exposed bed of a dried up Pleiocene lake and erosion through millennia have given us the stratified sand, clay and gravel sculptures we see today. They are quite unlike any Tuscan landscape I have ever seen, and have fascinated not only the local people, who have most enchantingly called them “fairies’ pyramids” among many other names, but no less a personage than Leonardo da Vinci: scholarly debate continues as to whether the Balze inspired the landscapes in the Mona Lisa and the Virgin of the Rocks among others.
We are on the Borro dell’Acqua Zolfina, a picturesque part of track 51, a four-hour circuit track which we picked up at Piantravigne, and this day was now bright, now moodily suffused with the light of a stormy mid-May sky. Other than a butterfly which fluttered alongside for a couple of metres, we had all of it to ourselves.
