Here I've posted a chronological list of Popes in order from Pope Innocent I to Pope Symmachus, with attached images. Pope Leo I is considered one of the most well known and respected Popes of all time. It was he who convinced Attila the Hun to cease his invasion of Italy, thus further cementing Papal power in Rome. Reigning from the Vatican as the head of the Roman Catholic Church and the Bishop of Rome, it is the Pope's duty to spread the gospel of Jesus throughout the Holy See and interpret God's will so Catholics may enter Heaven. Many Popes, especially earlier ones such as these, have achieved sainthood and are revered to this day.
