NOSTRADAMUS [III.23]
If France, you cross the Adriatic, you will find your self besieged among
islands and seas. Mahomet against you, more so the Adriatic, you will gnaw
the bones of horses and asses.
This describes a failed expedition of the French in the Adriatic sea. The French
fleet capitulates both due to the eastern resistance and nature's ire - most
probably due to the tidal waves following the comet striking the Ocean.
