But tonight, the moon
is truly gorgeous to behold.
.لكنّ منظر القمر اللّيلة رائع بالفعل
Doch ich gebe zu, heute ist der Mond
ganz außerordentlich schön.
Pero esta noche la luna es muy hermosa.
Aunque la luna está preciosa esta noche.

la lune est sublime.
Certo, è anche vero che oggi 
la luna è davvero splendida.
Mas hoje a lua está realmente bela.
Но луна сегодня особенно прекрасна.
