In my family there were no other artists to find.. .I was just a weird duck, right?”

“The unknown mountain nests in the inhospitable interior of southern Calabria are usually connected only by a mule track with the railway that runs close to the coast: whoever wants to go there has to walk on foot if he has no donkey at his disposal. I think back to that warm afternoon in the month of May when we the four of us, after a long, tiring ride in the harsh sun, packed with the heavy burden of our backpacks, sweat-dripping and a little gasping, entered the city gate of Palizzi..”

“When someone forgets himself, this by no means makes him altruistic; when a thinking person forgets himself, he immediately also forgets his fellowman, he loses himself and his humanity by becoming engrossed in his subject. Thus he is in a sense more contemplative than a feeling person.”
