Excellent summary...thanks for posting...read an excellent fictionalized version of the siege of Malta that is well-researched and highly recommended: The Religion by Tim Willocks...Neither Islam nor Catholicism comes off well in this period due to the fanaticism and cruelty of the Moors and the corruption within the church, primarily in the highest offices...all historically documented.
That was 100-200 years earlier, before Martin Luther. By the time of the Battle of Lepanto, the Council of Trent was over and a saint pope was in charge.
