Focusing on Shelley's 'Italian experience', the present study both addresses itself to the living context which nurtured Shelley's creativity, and explores a neglected but essential component of his work. The poet's four years of self-exile in Italy (1818-1822) were, in fact, the most decisive of his career. As he responded to Italy, his poetry acquired a new subtlety and complexity of vision. Endowed with remarkably keen powers of absorption, the poet imaginatively reshaped the rich cultural heritage of Italy and the vital qualities of its landscape and climate.
