That's the good thing about being halved. One understands the sorrow of every person and thing in the world at its own incompleteness. I was whole an… - Italo Calvino

If you choose to believe me, good. Now I will tell you how Octavia, the spider-web city, is made. There is a precipice between two steep mountains: the city is over the void, bound to the two crests with ropes and chains and catwalks. You walk on the little wooden ties, careful not to set your foot in the open spaces, or you cling to the hempen strands. Below there is nothing for hundreds and hundreds of feet: a few clouds glide past; farther down you can glimpse the chasm's bed.
This is the foundation of the city: a net which serves as passage and as support. All the rest, instead of rising up, is hung below: rope ladders, hammocks, houses made like sacks, clothes hangers, terraces like gondolas, skins of water, gas jets, spits, baskets on strings, dumb-waiters, showers, trapezes and rings for children's games, cable cars, chandeliers, pots with trailing plants.
Suspended over the abyss, the life of Octavia's inhabitants is less uncertain than in other cities. They know the net will only last so long.

"You are about to begin reading Italo Calvino's new novel, If on a winter's night a traveler. Relax. Concentrate. Dispel every other thought. Let the world around you fade.

I don't want to be disturbed!" Maybe they haven't heard you, with all that racket; speak louder, yell: "I'm beginning to read Italo Calvino's new novel!" Or if you prefer, don't say anything: just hope they'll leave you alone."

You cast another bewildered look at the books around you (or, rather: it was the books that looked at you, with the bewildered gaze of dogs who, from their cages in the city pound, see a former companion go off on the leash of his master, come to rescue him)
