The Prophesies of St John Bosco

Given the day that's in it, a friend mentioned to me the prophesies of Don Bosco. This sent me on-line where I found more than one set of prophesies...
The first set mainly relates to 19th Century European policies, including this message for the Austrian Emperor:

Thus says the Lord to the emperor of Austria: "Be of good cheer and look after
My faithful servants and yourself. My wrath is now spilling over all the nations
because they want to make people forget My laws, glorifying those who defile
them and oppressing My faithful adherents. Will you be the rod of My power? Will
out carry out My inscrutable design and become a benefactor of the world? Rely
on the Northern Powers, but not on Prussia. Enter into relations with Russia,
but form no alliance. Join forces with Catholic France; after France, you shall
have Spain. All together, become one in will and action.

The next prophesy is at the bottom of this page:

In a prophetical dream of Don Bosco, he saw two saints holding strips. In the
strip of one of the angels, it was written "LEPANTO 1571". In the strip of the
second angel, it was written "199_". Saint John Bosco knew that it was the
indication that of a year, and wrote the number of the year, but erased later.
Saint John Bosco was so impressed with the dream, that the scene described by
him was perpetuated in the two columns at the main entrance of his Church, in
Roma. What took place in 1571 was the Battle of Lepanto, between Muslims and
Catholics. What will happen in 1999?

I'm not sure what church is being referred to - there is a large Salesian Church near Termini railway station - I shall have to look when next there.
The ever-fascinating Multicultural Prophesies and Predictions Index includes the following:

In the midst of this endless sea, two solid columns, a short distance apart,
soar high into the sky. One is surmounted by a statue of the Immaculate Virgin,
at whose feet a large inscription reads Auxilium Christianorum (Help of
Christians). The other, far loftier and sturdier, supports a Host of
proportionate size, and bears beneath is the inscription Salus credentium
(Salvation of believers).
The flagship commander -- the Roman Pontiff --
standing at the helm, strains every muscle to steer his ship between the two
columns, from whose summits hang many anchors and strong hooks linked to chains.
The entire enemy fleet closes in to intercept and sink the flagship at all
costs. They bombard it with everything they have: books and pamphlets,
incendiary bombs, firearms, cannons. The battle rages ever more furious. Beaked
prows ram the flagship again and again, but to no avail, as unscathed and
undaunted, it keeps on its course. At times, a formidable ram splinters a gaping
hole in its hull, but immediately, a breeze from the two columns instantly seals
the gash.
Meanwhile, enemy cannons blow up; firearms and beaks fall to
pieces; ships crack up and sink to the bottom. In blind fury, the enemy takes to
hand-to-hand combat, cursing and blaspheming. Suddenly the Pope falls, seriously
wounded. He is instantly helped up, but struck a second time, dies. A shout of
victory rises from the enemy, and wild rejoicing sweeps their ships. But no
sooner is the Pope dead than another takes his place. The captains of the
auxiliary ships elected him so quickly that the news of the Pope's death
coincides with that of his successor’s election. The enemy's self-assurance
wanes.
Breaking through all resistance, the new Pope steers his ship safely
between the two columns; first, to the one surmounted by the Host, and then the
other, topped by the statue of the Virgin. At this point, something unexpected
happens. The enemy ships panic and disperse, colliding with and scuttling each
other.
Some auxiliary ships, which had gallantly fought alongside their
flagship, are the first to tie up at the two columns. Many others, which had
fearfully kept far away from the fight, stand still, cautiously waiting until;
the wrecked enemy ships vanish under the waves. Then they too head for the two
columns, tie up at the swinging hooks and ride safe and tranquil beside their
flagship. A great calm now covers the sea.

With the additional note:

There will be an Ecumenical Council in the next century, after which there will
be chaos in the Church. Tranquility will not return until the Pope succeeds in
anchoring the boat of Peter between the twin pillars of Eucharistic Devotion and
Devotion to Our Lady. This will come about one year before the end of the
century.
