On 11 September 1683, Poland’s King John

Sobieski arrived in the hills above Vienna to lift the two month siege of the Hapsburg Capital. He lit up

the sky with shot to shed light on a giant red cross flag to raise the morale of the exhausted defenders.

The next afternoon Sobieski led a charge of troops from a coalition of Catholic countries which drove the

Caliph’s best soldiers, the Janissaries from the field of fight, ending the siege. In gratitude for saving

Christian Europe, Popes have honored the Polish Monarch by naming a room in the Vatican Museum,

the Sobieski Room. In that room is a floor to ceiling painting displaying his victorious charge against the

Ottoman forces who had just penetrated Vienna’s defenses.
