das neuen Mut schöpfen, Prinz Itherus.
Trabajaremos aún más duro ahora

Vos paroles bienveillantes
nous donnent du cœur à l’ouvrage.
Dopo i vostri complimenti, nobile Iselus,
 possiamo impegnarci ancora di più.
Vamos nos esforçar ainda mais
 com esse elogio, Iselus-sama.
Слышать такие слова от вас,
Исельс, большая честь.
