The cots, the palaces and valleys here,
Are nought to me, their charm, alas! is fled;
Floods, rocks, and forests, solitudes so dear
One soul is wanting, and all else seems dead

[Que me font ces vallons, ces palais, ces chaumières,
Vains objets dont pour moi le charme est envolé?
Fleuves, rochers, forêts solitudes si chères,
Un seul être vous manque et tout est dépeuplé!]

Alphonse de Lamartine (1790-1869) French poet and statesman

Alt. trans. ["Isolation"]:
"What for me do these valleys, these palaces, these cottages,
Vain objects of which for me the charm has fled?
Streams, rocks, forests, solitudes so dear,
One single being from you is missing, and everything is depopulated."

Alt. trans.:
"Sometimes, when one person is missing, the whole world seems depopulated."
