The first vault-section's fresco depicts the victory of European forces over the Ottomans at Battle of Saint Gotthard in 1664. It was painted by the Austrian-born Stephan Dorfmeister (1725–1797). The characters in large lettering (known as a "chronostikon") in the Roman inscription on one side of the picture conceal the year of the battle: 1664. The English translation of the legend: “The Moon is spread out on the ground by the arms of King Lipót” (Leopold I, 1640–1705, also Holy Roman Emperor), and on the opposite side: “As the foe of the faith ran routed by Thee, so let this place be in safety under Thy protection, Our Lady.”
