"I am an atheist, and if an atheist and a pope think the same things, there must be something true."

Oriana Fallaci willed the bulk of her library to a pontifical university because of her esteem for Pope Benedict XVI.

Oriana Fallaci had described the pontiff as an ally in her campaign to rally Christians in Europe against what she saw as a Muslim crusade against the West. As she battled breast cancer last year, she had a private audience with Benedict, who was elected only a few months earlier, at the papal summer residence in Castel Gandolfo.

In one of her final interviews, Fallaci told The Wall Street Journal: "I am an atheist, and if an atheist and a pope think the same things, there must be something true."

Benedict was surprised by the gift of the books, which dated back as far as the 17th century and included volumes about the formation of modern-day Italy, American history, philosophy and theology, said Monsignor Rino Fisichella, rector of the Pontifical Lateranense University in Rome.

"The veneration that she had for you, Holy Father, persuaded her to make this donation, which will be known as the Oriana Fallaci Archives," Fisichella said during a ceremony at the university Saturday to announce the gift of the books.
