PLACE DU CARROUSEL (Jacques Prévert)

Place du Carrousel
al tramonto di un bel giorno d'estate
il sangue di un cavallo
ferito e senza redini
scorreva sul lastrico

E il cavallo era la'
ritto immobile
su tre piedi
E l'altro piede ferito
ferito e lacerato
ciondolava.

Proprio a fianco
ritto immobile
vi era anche il cocchiere
e la carrozza anch'essa immobile
inutile, come un orologio rotto.
E il cavallo taceva
il cavallo non si lagnava
il cavallo non nitriva
egli era la'
aspettava
ed era cosi' bello, cosi' triste, cosi' semplice
e cosi' ragionevole
che non era possibile trattenere le lacrime

Oh
giardini perduti
fontane dimenticate
praterie soleggiate
oh dolore
splendore e mistero dell'avversita'
sangue e bagliori
bellezza percossa
Fraternita'


Place du Carrousel
towards the end of a beautiful summer day
the blood of a horse
injured and unharnessed
streamed
onto the pavement.

And the horse was there
standing
motionless
on three feet.
And the other wounded foot
wounded and torn
hung.

Right next to it
standing
motionless
there was also the coachman
and the carriage that was also motionless
useless as a broken clock.
And the horse was silent
the horse didn’t complain
the horse didn’t whinny
it was there
it waited
and it was so noble so sad so simple
and so reasonable
that it wasn’t possible to hold back tears.

Oh
lost gardens
forgotten fountains
sunlit meadows
oh suffering
splendor and mystery of adversity
blood and sparks
beaten-up beauty
Brotherhood.
