A Guide to the Study of the Works of Robert Browning

Robert Browning, the great Victorian poet, is often claimed to be hard to understand, largely on account of the obscurity of his language, the complexity of his thought, and his poetic style. The Browning Cyclopaedia, first published in 1891, presents an exposition of the prominent ideas of each poem, as well as its tone, its sources – historical, legendary or fanciful – and a glossary of every difficult word or allusion which might obscure the poem’s meaning. This volume remains indispensable for students of Robert Browning, as well as those interested in the general aesthetic climate of Victorian poetry.
