Among the surviving books of the Sibylline Oracles, Book 7 has aroused particular interest because of its allegedly Jewish-Christian and Gnostic character. A. Rzach has described the author of Book 7 as “ein durch die Gnosis beeinflusster, vielleicht aus dem Judentume … hervorgegangener Christ.” J. Geffcken regards the book as a product of Jewish Christianity with traces of Gnostic influence. And A. Kurfess, in an article which bids fair to become the standard introduction for English-speaking students of the Sibyllines, calls it “purely Christian,” while also indicating the presence of “gnosticizing views.”. Given the lack of sustained interest in these writings during recent years, I think it not unimportant to examine the adequacy of these labels and to determine whether there is sufficient evidence to support them.
