The Christian army's great and puissant guide,
To assault the town that all his thoughts had bent,
Did ladders, rams, and engines huge provide,
When reverend Peter to him gravely went,
And drawing him with sober grace aside,
With words severe thus told his high intent;
"Right well, my lord, these earthly           you move,
But let us first begin from Heaven above:

The aid, assistance, and the help obtain
Of all the blessed of the heavenly rout,
With whose support you conquest sure may gain;
First let the priests before thine armies stout
With sacred hymns their holy voices strain.
