Prophecy of the Popes.

The longest and final verse predicts the Apocalypse:^[16]

In persecutione extrema S.R.E. sedebit. Petrus Romanus, qui pascet oves in multis tribulationibus, quibus transactis civitas septicollis diruetur, & judex tremendus judicabit populum suum. Finis.

This may be translated into English thus:

In the final persecution of the Holy Roman Church, there will sit [i.e., as bishop]. Peter the Roman, who will pasture his sheep in many tribulations, and when these things are finished, the city of seven hills [i.e. Rome] will be destroyed, and the dreadful judge^[a] will judge his people. The End.
