I don't know what to make of these. They certainly could be forgeries from the mid 1500's when they were "discovered," but some of them hit pretty close to home. The prophecy for Pope Pius VII simply says Aquila Rapax ("a rapacious eagle"), and it was indeed Pius VII who was kidnapped by Napoleon and forced to suffer at his hands. Napoleon certainly can be described as rapacious, but more importantly, his personal emblem was an eagle. Another example is Pius IX, who has the prophecy Crux de Cruce ("a cross from a cross"). Pius IX suffered much from the atheistic Italian nationalist movement, spearheaded by the House of Savoy, whose emblem was a cross.
You may be aware that these prophecies are the origin of the oft repeated assertion that, following John Paul II, there were only two popes left until the end of the world. Now that Benedict is on the throne, only one more left after him, according to Malachy. Benedict's motto from St. Malachy reads Gloria Olivae, "the glory of the olive," and has long been associated with the Benedictines. It is interesting that in this book I am reading (written in the 1960's), this prophecy is interpreted as meaning that this pope will either be a Benedictine or will take the name Benedict. It is interesting that Ratzinger did in fact take that name. But did he do this in deference to the prophecies?
The final pope on St. Malachy's list is Petrus Romanus ("Peter the Roman"), of whom it says:
In the final persecution of the Holy Roman Church there will reign Peter the Roman, who will feed his flock amid many tribulations, after which the seven-hilled city will be destroyed and the dreadful Judge will judge the people. The End.
If we assume that this Peter the Roman comes right after Gloria Olivae (and there is no textual reason to suggest he doesn't), then right now we are on the second to last Pope before the final persecution and judgment.
