Byron is the representative poet of active Romanticism,but there are decadent colors in his poems.Byron suffered from intermittent fevers,which contemporary medical researchers attribute to malaria.His fevers profoundly affected the appearance of decadence.The intermittent fevers caused somatic anxiety,and also stimulated the life impulse,which made his decadence manifested as"loneliness and world-weariness"and"carnal rebellion"in his poems.The decadence in Byron's poetry is the concentrated embodiment of the romantic individual life deeply repressed in the political,marriage and ecological environment since the Industrial Revolution,and also the poet's irrational way to break away and rebel.This kind of decadence contains anti-modernity,anti-grand narration,advocating primitive vitality and other factors,which is the polyphony played by the European social living environment in this era.
