Siege of Vienna Raised by John Sobieski

O, for a kindling touch from that pure flame
Which ministered, erewhile, to a sacrifice
Of gratitude, beneath Italian skies,
In words like these: "Up, Voice of Song! proclaim
Thy saintly rapture with celestial aim:
For lo! the Imperial City stands released
From bondage threatened by the embattled East,
And Christendom respires; from guilt and shame
Redeemed, from miserable fear set free
By one day's feat, one mighty victory.
--Chant the Deliverer's praise in every tongue!
The cross shall spread, the crescent hath waxed dim;
He conquering, as in joyful Heaven is sung,
HE CONQUERING THROUGH GOD, AND GOD BY HIM."
