The young lion will overcome the older one,
On the field of combat in a single battle;
He will pierce his eyes through a golden cage,
Two wounds made one, then he dies a cruel death.
(Century 1, Quatrain 35)

In June 1559, Henry II participated in a jousting tournament against the Comte de Montgomery. Both men used shields embossed with lions. Montgomery was six years younger than Henry. The tournament is played on a field of ritual single combat. During the final bout, Montgomery failed to lower his lance in time. It shattered, sending a large splinter through the king's gilded visor (golden cage). Along with minor punctures in the face and throat, there were two mortal wounds. One splinter destroyed the king's eye; the other impaled his temple just behind the eye. Both penetrated his brain. Henry lingered for ten agonizing days before dying a cruel death.

From the enslaved people, songs, chants and demands,
The princes and lords are held captive in prisons:
In the future by such headless idiots
These will be taken as divine utterances.
(Century 1, Quatrain 14)

The French Revolution technically began when the Bastille was attacked on July 14, 1789. Members of the aristocracy were imprisoned and some were beheaded -- as did the mob, metaphorically, while engaging in violent actions.

From Castille, Franco will bring out the assembly,
The ambassador will not agree and cause a schism:
The people of Rivera will be in the crowd,
And they will refuse entry into the Gulf
(Century 9, Quatrain 16)

Spanish dictator Francisco Franco and his predecessor, Primo de Rivera, are actually mentioned by name in this prophecy. In 1936, the Republican government had Franco exiled to the Canary Islands. He later returned to Spain and organized a military junta. Spain was torn apart by a civil war at his return.
