Seven years later and do anyone of us know two bits more about Islam?
If you want to see nice battle of Lepanto scenes see this fresco in the gallery of maps in the Vatican Museums (dates from circa 1580-1583) or see the Vatican's Sala Reale or even the Palazzo Colonna in Rome's historic center.
And of the battle of Vienna...
"Vienna, as we saw, was almost taken and only saved by the Christian army under the command of the King of Poland on a date that ought to be among the most famous in history - September 11, 1683. But the peril remained, Islam was still immensely powerful within a few marches of Austria."
-The Great Heresies by Hilaire Belloc, 1938.
