Born Elisabeth Schüssler in Tășnad, in the Transylvanian region of the Kingdom of Romania, Professor Schüssler Fiorenza is a German feminist, theologian and Professor of Divinity at Harvard Divinity School. Schüssler Fiorenza identifies as Catholic and her work is generally in the context of Christianity, although much of her work has broader applicability.
Her treatment of the structure of Revelation (pp. 170-77) is truly insightful and is one of the more convincing proposals I've read.
The rest of the book, however, is too mired in critical methods and presuppositions to be helpful. She occasionally makes a solid point, but these tend to be basic enough that they can be gleaned from much sounder resources elsewhere.
This is a helpful scholarly treatment of Revelation, particularly on the subject of rhetorical interpretation. She majors on issues that affect the interpretation of Revelation, spending much less time on what is actually means.
