I came across an English version of this book many years ago, published by Picador. I must still have it somewhere. As a homage to Calvino, one of the authors I most admire, I tried this short translation. (Free Spanish version from the Italian below.)

"Is this your town?", the youngster would have asked.

"It's actually yours,"--a better answer he couldn't have got--"here you'll find everything you ask for."

Thus caught off guard, he'd hardly be able to utter a sensible wish. Heated up after climbing to that point, he'd just say: "I am thirsty!"

And the angel on the throne: "You just have to choose which one of these wells you fancy to drink from," and he pointed at two identical wells that opened up in the desert square.

The youngster--you just need to glance at him to notice how utterly lost he feels again. The crowned power in front of him now brandishes a scale and a sword, the attributes of the angel that guards over decisions and balances from the heights of the constellation of Libra.

- ¿Es esta tu ciudad?, habrá preguntado el joven.

- La tuya -mejor respuesta no habría podido recibir-, aquí hallarás todo aquello que pidas.

Tomado así de improviso, difícilmente sea el joven capaz de expresar un deseo sensato. Acalorado tras haber ascendido hasta allí, habrá dicho simplemente: - ¡Tengo sed!

Y el ángel en el trono: - Sólo debes elegir de cuál de estos pozos has de beber -y le habrá señalado dos pozos idénticos que se abren en la plaza desierta.

Al joven basta ahora con mirarlo para comprender hasta qué punto se siente otra vez perdido. La potestad coronada de pronto blande una balanza y una espada, los atributos del ángel que vela por las decisiones y los equilibrios desde lo alto de la constelación de Libra.
