For if the Christian Princes ever strive
To win fair Greece out of the tyrants’ hands,
And those usurping Ismaelites deprive
Of woful Thrace, which now captived stands,
You must from realms and seas the Turks forth drive,
As Godfrey chased them from Juda’s lands,
And in this legend, all that glorious deed,
Read, whilst you arm you; arm you, whilst you read.
