The Editor is responsible for the selection of the passages translated, and for the Introduction. He has also compared the translation with the original text, has satisfied himself of its general accuracy, and has made numerous suggestions.

The Translator is responsible for the fidelity of the translation in detail, and for its general tone and style. She has also drawn up the Indexes, and seen the work through the press.

For the selection of marginal references to the works of Dante the Editor and Translator are jointly responsible.

Both Translator and Editor desire to express their obligations to Mr. A.J. Butler, who has given them his ungrudging assistance in every difficulty, and whose learning and judgment have been invaluable.
