The German poet, Heinrich Heine (1797-1856), has long been a source for lieder by masters like Robert and Clara Schumann. Distancing itself from Romanticism, his poetry often exhibits irony, sarcasm, and satire, as here in 'Es liegt der heiße Sommer' ('To thy cheeks the fires of summer'). This makes it a challenge for setting original compositions. You will find a fine English translation of the poem, which was written in 1823, here.
