In 1857 appeared the "Fleurs du Mal" (Flowers of Evil), the volume of poems upon which Baudelaire's fame as a poet is founded. It was the result of his thirty years' devotion to the study of his art and meditation upon it. Six of the poems were suppressed by the censor of the Second Empire.

But the poet's own words are the best explanation of his aim and intention:--
